The system characteristics and application of large-power controllable bidirectional converter technology are introduced. With the actual engineering background of Hangzhou-Shaoxing Line, a specific optimization scheme of bidirectional converter is proposed. The advantages of this scheme are analyzed from the aspects of power supply performance, reliability, economy and engineering adaptability. Results show that compared with the current diode rectifier unit + regenerative energy absorption device scheme, the large power bidirectional converter technology has better application prospect in practical engineering.
