Abstract
This paper aims at the electrical design research on converter transformer area of a onshore converter station,to put forward a technically and economically reasonable scheme.Different transformer capacities,types and schemes have been compared and analysed based on the converter transformer area of a typical symmetrical unipolar connection,±5 00kV/2 000 MW scheme.And comparison has been done on converter transformer configuration,converter transformer and neutral point connection,pre-insert resistor connection and so on.Converter transformer area equipment selection and scheme of a onshore converter station recommended by this paper has the advantages of excellent economy and high reliability.It is suggested to apply three-phase transformer for converter transformer.Neutral point of the valve side of converter transformer is grounded by resistor or resistor and reactor.The pre-insert resistor is set in the valve side of converter transformer.A circuit breaker is set in each branch of converter transformer.3/2 circuit breaker shcheme is applied in grid side of converter transformer and the converter transformer is connected to the string respectively.关键词
