The integration and application of large capacity DC ice melting and static var compensation device with network provincial coordination
The main circuit topology of fixed DC ice melting and reactive power compensation device in 500kV Guanshan station is a 6-pulse bridge without converter transformer. The type of grid-side reactor is oil-filled iron core, also serves as phase controlled reactor in reactive power compensation mode. The device is direct accessed by the automatic voltage control system of East China Grid company, accepts scheduled command during reactive power compensation mode. The basic parameters, topology reconstruction scheme, ice melting line switching system, reactive coordination mechanism between East China Grid company and provincial grid company is introduced in this paper. The control scheme in typical operating mode is also described, and combined with field operating data, the effect of the device in overhead power transmission lines ice melting and reactive power compensation are analyzed.
