Three 330MW STG units are connected with the 150KV switchgear in form of generator-transformer unit. 4 CTs are installed at the busbar bushings on the generator outgoing side and neutral point side respectively. 3 PTs and 1 group of surge arresters are equipped on the generator outgoing side. The generator neutral point is earthed via a single transformer whose secondary side is connected with a shunt resistor; one end of the resistor is earthed. In addition, the generator is connected with the transformer with whole connection isolated-phase enclosed busbar and the HV auxiliary transformer as well as the excitation transformer is connected between the generator and the main transformer. The exciter adopts static self-shunt excitation system.
150KV配电装置采用采用3/2断路器接线方式，3台发电机组经主变压器升压接入150KV母线。全厂设置2台起动/备用变压器，作为电厂机组起动和备用电源，由150KV配电装置母线引接。设置1台150/20KV城市供电变压器（TFT）由150KV母线引接。150KV系统共有3回发-变组进线，2回起备变出线，1回TFT出线，4回线路出线，组成5个完整串。除过TFT外，所有变压器进线及出线回路均装设三相电压互感器，在150KV母线装设单相电压互感器。
The 150KV switchgear adopts two thirds CB connection and the 3 generators set are stepped up by 3 main power transformers and then connected to the 150KV busbar. 2 set of start-up/standby transformers are installed in the plant, serving as plant start-up and standby power source, which are connected from the 150KV busbar. One 150/20KV TFT is equipped, which is originated from the 150KV busbar for the 150KV system, there are totally 3 in-coming lines are available for generator-transformer unit, 2 outgoing lines for SST, one outgoing for TFT and 4 outgoing lines. Therefore, 5 complete incoming and outgoing loops are formed. Except the TFT, all the transformers are fitted with 3-phase PTs for in-coming and outgoing lines. Additional, single phase PTs are fitted for the 150KV busbar system.
