Description
Summary:Nowadays, development of multi-terminal HVDC systems is driven by aim to connect remote loads, offshore wind power plants and increase of energy trading. Operation of meshed multi-terminal systems is hard to imagine without fault clearing devices. The aim of this paper is to investigate operation of a hybrid circuit breaker under simulated system fault conditions. A simulation of the HVDC systems with embedded circuit breakers allows study of its operation and stresses applied to the equipment during and after fault clearance. Understanding of the circuit breaker operation is an important step towards understanding of design and the development of test criteria for a real breaker. Simulated HVDC system cases presented by point-to-point connections, three and four terminal systems.
