6 FAQs about [High voltage circuit breaker electric energy storage control circuit]

What is a HVDC circuit breaker?

The operation indicates that the HVDC circuit breaker can accurately and reliably isolate faults and ensure the safe and stable operation of the DC system.

What are the energy absorption characteristics of DC circuit breakers?

The energy absorption characteristics of the energy absorption branch are closely related to the characteristics of the transient energy flow in the DC system, which is the basis for the fault analysis in the DC grid (CIGRE TB 034 1989). There are many factors that affect the energy absorbed by the DC circuit breakers’ MOSA.

Can a voltage source inverter help a high-voltage DC circuit breaker?

How to test a hybrid HVDC circuit breaker?

Alternatively, in the case of a hybrid HVDC circuit breaker, the performance of current interruption (current blocking) as well as the steep transient voltage withstand after current zero by a power electronic device, and the performance of voltage restriction by the MOSA unit are demonstrated as the first step of the testing method.

How does a voltage zero-crossing hybrid DC circuit breaker work?

The voltage zero-crossing hybrid DC circuit breaker realizes current transfer by controlling the coupling current in the circuit to inject a voltage with a polarity opposite to the system voltage, and the control circuit and the main circuit are isolated from each other.

What are the requirements for 80 kV HVDC circuit breaker module?

The results correspond to the requirements for an 80 kV HVDC circuit breaker module with an energy dissipation capability of 8.7 MJ. The energy absorption dissipated by the MOSA unit should surpass the requirements in HVDC power systems.
