Garantire la lubrificazione critica nelle turbine eoliche durante gli scenari di interruzione della rete

Un approccio basato sul sistema DC/DC CBS-10K per proteggere asset meccanici di alto valore

Il contesto dell'energia eolica

L'energia eolica svolge un ruolo chiave nella transizione globale verso la generazione di elettricità da fonti rinnovabili.

Le moderne turbine eoliche sono macchine altamente ottimizzate, che combinano grandi strutture meccaniche con sistemi elettrici e di controllo sempre più complessi.

Oltre alla produzione di energia, la protezione degli asset durante condizioni operative anomale — come la perdita della rete elettrica — è diventata un fattore determinante nella progettazione per i produttori di turbine eoliche.

In questo contesto, i sistemi di alimentazione di emergenza a breve durata ma altamente affidabili sono essenziali per proteggere i sottosistemi meccanici critici, il cui guasto può portare a gravi conseguenze economiche e operative. .

La sfida: lubrificazione critica in condizioni di assenza di rete (Grid-Off)

Uno dei sottosistemi più critici all'interno di una turbina eolica è il sistema di lubrificazione associato ai meccanismi di orientamento e posizionamento meccanico che operano sotto carico elevato.

L'applicazione descritta corrisponde a grandi turbine eoliche onshore con una potenza di circa 7 MW e oltre .

In questo scenario, la lubrificazione è direttamente collegata al sistema di imbardata (yaw system) e ai relativi meccanismi di orientamento necessari per posizionare in sicurezza il rotore rispetto alla direzione del vento.

Lubrificazione del sistema di imbardata (Yaw System)

Il sistema di imbardata è responsabile dell'orientamento della navicella e del rotore verso la direzione del vento. Include grandi cuscinetti e meccanismi a ingranaggi che operano sotto carichi meccanici molto elevati.

Una lubrificazione insufficiente può portare a un'usura accelerata, gravi danni meccanici e lunghi periodi di inattività della turbina. Questi sistemi meccanici sono di alto valore e difficili da riparare , rendendo la continuità della lubrificazione un requisito non negoziabile .

Durante gli scenari di interruzione della rete (grid-off), la lubrificazione deve rimanere attiva per:

Evitare il contatto metallo-metallo.
Completare le procedure di arresto controllato.
Proteggere gli asset meccanici con costi di sostituzione che vanno da decine di migliaia a diverse centinaia di migliaia di euro .

Per affrontare questa sfida, è stata selezionata una soluzione di backup DC/DC ad alta potenza basata sul convertitore CBS-10K per garantire la stabilità elettrica durante la perdita della rete.

Perché le architetture di backup tradizionali sono inadeguate per le turbine dei nostri clienti

Storicamente, le soluzioni di backup si sono basate su:

Sistemi basati su inverter DC/AC con commutazione ritardata.
Architetture UPS convenzionali.
Convertitori DC/DC a bassa potenza senza capacità di sovraccarico dinamico.

Questi approcci non sono riusciti a soddisfare le reali esigenze dei sistemi di lubrificazione dei nostri clienti perché:

I ritardi di commutazione introducono cali di tensione.
I VFD (Azionamenti a Frequenza Variabile) sono estremamente sensibili all'instabilità a livello di microsecondi.
Le elevate correnti di spunto durante l'avvio del motore causano il crollo della tensione.

Di conseguenza, le pompe di lubrificazione potrebbero fermarsi prima del completamento del ciclo, esponendo i componenti meccanici a danneggiamenti.

Una soluzione centrata sul sistema DC/DC basata sul CBS-10K

Per superare queste limitazioni, è stata implementata un' architettura di backup incentrata sul sistema DC/DC .

Al cuore della soluzione si trova il convertitore DC/DC CBS-10K , che funge da ponte di potenza tra il sistema di batterie e i VFD (azionamenti a frequenza variabile) che alimentano le pompe di lubrificazione e i motori ausiliari.

Principi chiave della progettazione:

Intervento immediato in caso di perdita della rete.
Assoluta stabilità della tensione , anche in presenza di elevati carichi transitori.
Capacità di sovraccarico a breve termine per supportare l'avvio del motore.
Design compatto e robusto , ideale per l'integrazione all'interno della navicella (nacelle).

Piuttosto che fornire una lunga autonomia, l'obiettivo è garantire il completamento del ciclo di lubrificazione in tutte le condizioni di assenza di rete .

Perché l'approccio DC/DC con il CBS-10K funziona

La soluzione CBS-10K ha successo dove altre architetture hanno fallito grazie a:

Elevata densità di potenza.
Capacità di sovraccarico a breve termine.
Eccellente risposta dinamica.
Alta tolleranza alle correnti di spunto.
Robustezza industriale comprovata in ambienti esigenti.
Pronto per la certificazione UL con solo piccoli adattamenti.

Cosa fondamentale, la soluzione si basa su una piattaforma industriale standard , riducendo al minimo i rischi tecnici e della catena di approvvigionamento.

Risultati e Benefici Operativi

Sul campo, la soluzione di backup basata su DC/DC ha dimostrato:

Prestazioni stabili durante gli eventi di assenza rete (grid-off).
Eliminazione degli scatti involontari dei VFD.
Completamento affidabile dei cicli di lubrificazione.
Protezione efficace di asset meccanici di alto valore.
Riduzione del rischio operativo ed eliminazione di eventi OPEX ad alto impatto economico.

Installazione Onshore – Validità Offshore

La soluzione è attualmente impiegata su piattaforme di turbine eoliche onshore , incluse turbine ad alta potenza nella classe multi-megawatt (≈7 MW) , dove è richiesto un backup di potenza rapido, affidabile e di breve durata.

Questa classe di grandi turbine eoliche onshore è soggetta a una forte domanda di mercato , con volumi di produzione annuali che variano tipicamente da diverse centinaia fino a circa mille unità all'anno.

Dal punto di vista tecnico, lo stesso approccio CBS-10K DC/DC è valido anche per applicazioni offshore , dove si applicano requisiti simili di stabilità e rapidità di intervento all'interno di architetture di sistema ridondanti.

Punti Chiave (Key Takeaways)

La continuità della lubrificazione è mission-critical durante i guasti alla rete.
L'instabilità elettrica si traduce direttamente in rischio meccanico .
Nelle grandi turbine eoliche onshore, i guasti meccanici hanno un impatto economico elevatissimo .
Un'architettura DC/DC CBS-10K alimentata a batteria garantisce un backup di potenza rapido e affidabile.

How to Select the Right Current Transformer for Industrial Applications

Before selecting a current transformer (CT) in an industrial plant, critical factors need to be evaluated to ensure the chosen device is suitable for the plant's specific needs.

Current transformer applications

How does a current transformer work? Measurement or Protection?

Determine whether the Current Transformer will be used primarily for accurate measurements (e.g., energy accounting) or for protection purposes (e.g., detecting overcurrents).

CTs for measurement require high precision, as well as those for protection must respond reliably to prevent failures.

Electrical CT Parameters

Consideration of electrical current transformer parameters is important in designing a power distribution system.

Primary Current

Assess the maximum current that the primary circuit can carry. The Current Transformer must be able to handle this current without saturating.

Secondary Current

The standard secondary current is typically 1A or 5A. The choice depends on the plant's preferences and compatibility with existing equipment.

Current transformer Class

The classes of low-voltage current transformers are specified based on the required accuracy for measurements and are standardized to ensure proper interpretation of results.

Common classes for low voltage protection current transformers:

5P10 / 5P15 / 5P20

Initial Number (5): indicates the precision of the CT's measurement when used for protection purposes. In these examples, "5" corresponds to a precision of 5%. These values indicate how much the measured value by the CT can vary from the real value existing during an overcurrent event.

Letter (P): the letter "P" indicates that the CT is intended for protection purposes, meaning it is designed for detecting overcurrents or anomalies in the electrical system.

Subsequent Number (10, 15, 20): indicates the number of times the current transformer can withstand an overcurrent without saturating (within the accuracy class). In this case, "10","15","20" means that the CT can withstand an overcurrent of 10,15,20 times.

Common classes for low voltage measurement current transformers :

0.5 / 0.2

0.5 : indicates a precision class of 0.5%, commonly used for standard measurements in industrial plants.

0.2 : indicates a precision class of 0.2%, suitable for high-precision measurements in more advanced applications.

There may be additional subclasses (e.g., 0.2S) indicating further specifications regarding waveform and dynamic behavior of the current transformer. The choice of the class depends on the specific requirements of the application and the precision needed for measurements.

Are you searching for current transformers that meet the classes described above? Discover our range of current transformers.

Frequency Range

Ensure the Current Transformer operates effectively within the system frequency range where it will be installed.

Type of Installation

Current transformers can be classified based on where and how they are installed. The main categories are:

Indoor vs. Outdoor

CTs intended for outdoor use are designed to withstand adverse environmental conditions such as rain, snow, extreme temperatures and UV radiation. Those for indoor use are generally utilized in controlled environments, such as electrical panelboards.

Bar Type, Window Type or Wound Type

Bar type CTs are installed directly onto a rigid conductor. Window type CTs have an opening through which the primary conductor passes. Wound type CTs have the primary conductor wound around the transformer core.

Environmental Conditions

Ambient Temperature: consider temperature variations in the installation area and select a CT that can operate within these limits.

Humidity and Condensation: in high humidity environments or where there is a risk of condensation, current transformers must have improved insulation characteristics to prevent short circuits or failures.

Corrosion: in aggressive environments, such as industrial areas with chemical presence, or coastal zones where air salinity is high, CTs must have adequate protection against corrosion.

Altitude : altitude can affect CT performance since air density decreases with increasing altitude, affecting insulation properties. CTs for high altitudes are designed to maintain their performance in such conditions.

Physical Characteristics

Size, model and Mounting: ensure the current transformer fits the available space and that the model (bar type, wound type, etc.) is compatible with the installation.

Standards and Regulations

Compliance with Standards: verify that the CT complies with relevant international (e.g., IEC) or national standards for the application.

Certifications: check for any certifications required for use in particular or hazardous environments.

Additional Considerations

Ingress Protection (IP Rating) : indicates the level of protection against the entry of solid objects and liquids.

Withstand and Thermal Load: CTs must be capable of withstanding thermal effects and dynamical strengths generated by short circuit conditions and long time overcurrent on primary conductor without deteriorating.

Supplier and Technical Support

Supplier Reliability: choose products from reliable suppliers with a good reputation for quality and durability.

Technical Support: receive expert guidance in defining the optimal CT parameters tailored to your specific application, ensuring accurate measurements and reliable performance.

By carefully evaluating these factors, a technician can select the most suitable current transformer to ensure reliable performance and safety in the industrial plant.

What Damage Do Current Overloads Cause in Asynchronous Three-Phase Motors?

Asynchronous Three-Phase Motors , capable of triggering a sequence of unfavorable events that jeopardize the equipment's structural integrity and its operational efficiency . In an era where real-time monitoring and predictive maintenance are increasingly prevalent, understanding the ramifications of these events is essential for optimizing motor lifespan and reducing downtime .

The negative Consequences of Overheating

Overheating arises directly from current overloads. When a motor exceeds its rated capacity, the internal resistance of the windings increases, which converts electrical energy into heat. This scenario leads to multiple problems.

Decreased Energy Efficiency

The motor's efficiency is reduced by the excess heat generated from overload currents, leading to higher energy consumption for accomplishing the same work, thereby elevating operational costs.

Accelerated Aging of Components

High temperatures hasten the wear and tear of crucial motor components such as insulators and lubricants, which may shorten the motor's useful life.

Mechanical Stress Due to Thermal Expansion

Disproportionate expansion of motor components from heat can lead to internal misalignments, which can increase the rate of wear and the likelihood of mechanical failures.

Extreme Motor Damage

In the most severe cases, the intense heat from overloads can cause devastating damage, including the melting of windings or, in the worst scenarios, fires.

Insulation Integrity & Motor Safety

Subsequent to overheating, insulation integrity is the next significant concern. The safe operation of any electric motor relies on the condition of its insulation:

Short Circuits

Weakened insulation can cause short circuits within the motor windings, increasing the current and generating additional heat, perpetuating a harmful cycle of degradation.

Earth Leakage Risks

Deteriorating insulation may lead to current leakage to earth, creating a hazard of electric shock and potentially triggering protective devices that could interrupt motor operation.

Weakened Dielectric Strength

Once insulation integrity is undermined, the motor's ability to endure electric voltages without arcing or leakage is compromised, putting the equipment's consistent performance at risk.

Proactive Maintenance: Transforming Electric Motor Management

In the digital era, marked by the proliferation of the Internet of Things (IoT), the role of telemetry and advanced analytics in preempting and pinpointing operational issues is more pivotal than ever.

Leveraging cutting-edge solutions like Artificial Intelligence (AI) and Machine Learning (ML), we can now sift through operational data with unparalleled precision and speed.

This real-time analysis uncovers emerging trends and potential precursors to current overloads, along with their implications. As a result, there is a paradigm shift from traditional reactive maintenance to a forward-thinking, proactive strategy .

This proactive maintenance prioritizes the early detection and immediate rectification of irregularities, dramatically reducing downtime and significantly enhancing the reliability and longevity of these essential electric motor assets.
