6、installed in T.J.AWAR AWAR power plant, which is provided with 150kV distribution equipment. Four circuits are led out from such equipment and then connected with the Indonesia 150kV system. A 3/2 CB wiring mode is used for 150kV distribution equipment. Two generating units are stepped up via a main
7、 transformer and then switched in 150kV busbar. The entire power plant is provided with one startup/backup transformer as the startup and backup power supply for the units of the power plant, which is connected via the busbar of 150kV distribution equipment. 150kV distribution equipment is arranged
8、outdoors in a middle-sized form, while CBs are dually arrayed. Each string of incoming and outgoing line circuit occupies 2 intervals. The main transformer and the outgoing line set in Circuit 1 form one complete string, and then the string is arranged in two intervals; the incoming line of the star
9、tup/standby transformer and the outgoing line set in Circuit 1 form one complete string, and then the string is arranged in two intervals; the main transformer in Circuit 1 and the urban supply transformer outgoing line as well as transformers are arranged in the interval of a complete string and oc
10、cupies two intervals. Both ends of the busbar are provided with a busbar earthing switch. Two 350MW turbo generator units are switched in 150kV distribution equipment in a connection unit form of generator-transformer bank. The outgoing end of the generator and the outgoing bushing at the end of a n
11、eutral point are equipped with four groups of current transformers; the outgoing end of the generator is equipped with three groups of potential transformers and one group of surge arresters; the neutral point of the generator is earthed via the secondary resistance of a single phase earthing transf
12、ormer. The generator and the main transformer are connected by using continuous enclosure-type isolated phase busbar. A high voltage station transformer and an excitation transformer are connected from between the generator and the low voltage side of the main transformer. A static self-shunt system
13、 is used for the excitation of the generator. Two voltage levels of 6.3kV and 400/230V are used in the station-service power system. The rated voltage of a medium voltage electric motor is 6kV, and the rated voltage of a low voltage electric motor is 380V/220. 2350MW coal-fired generating units are
14、installed in T.J.AWAR AWAR power plant. According to the load statistics of electrical equipment in all process systems of the power plant, each generating unit is provided with one high voltage station transformer, which is used to supply power for electrical equipment for the unit plant. The power supply at the high voltage side of the high voltage station transformer Indonesia T.J.
