| Abstract |
Wind farms of the current generation are connected to existing distribution systems onshore. The substantial submarine cable systems that are required raise concerns of a large net capacitive charge, particularly under low export conditions. For an offshore wind farm connection, it is therefore important for the Distribution Network Operators (DNOs) to ensure that the circuit breakers installed at and near the DNO‟s point of common coupling (PCC) are fit for purpose with respect to switching operations and fault clearance duty. This paper summarizes the results of transient recovery voltage (TRV) studies carried out for a 60MW offshore wind farm connection to assess the capability of circuit breakers at the PCC and at neighbouring DNO system locations. The proposed circuit breakers are assessed against reference TRVs specified in IEC 62271-100:2001 to assess fitness for purpose. |
