The hydroelectric station of type of a pilot a ship into a harbour that power station of humanitarian county Dan Dongshui is development of stair of red river region, capacity of aircraft of power station general assembly is 3130kW, among them two are 1250kW and group of water turbogenerator of a 630kW. The dynamo is rated voltage is 6.3kV, dynamo power factor is 0.8, 3 dynamoes all are synchronous dynamo. Power station year electricenergy production H of · of 14 million KW. 1995 with big electrified wire netting and net, at the same time the power station has independent self-confessed area. Get online every year to be with the scale of self-confessed bear 3 than one.

Because the power supply system of the power station has two parts to comprise, power station must reasonable the power factor that adjusts a dynamo, do not have the demand of result with satisfying two systems to be opposite. In the power station inside self-confessed area, how to contain in all transformer capacity 3000kVA, transformer is close 40, and it is more vintage high cost can transformer, change of the bear that use phone is big, without work load demand big also. On 10kV circuitry with 400V low pressure the user all did not install capacitor. If use installation capacitor to compensate,do not have result, raise the power factor of road of self-confessed district interior lines, one-time investment is large, capacitor moves uphold charge tall, often return meeting occurrence " to cross filling " phenomenon. Because this is passed,undertake to factor of power of power station dynamo timely adjust, of line of compensatory and self-confessed division without work load, the economy that improves line moves, relatively reasonable. And the power factor of net bear, the requirement of Electricity Department door is very strict also, formulary power factor must is 0.8. If little hair does not have result punishment, much hair not to have achievement award, award is punished with 0.8 for the standard, low 0.01 award get online that month 0.1% of charge of electricity, tall 0.01 punish get online that month 0.5% of charge of electricity, namely award punishs the regulation of 5. Although the regulation of Electricity Department door is very strict, but our power station is in different season, according to water quantity and the characteristic that bear changes, adjust the power factor of the dynamo reasonably, annual not only the need that makes sure self-confessed area does not have work load, and still suffer much hair of electrified wire netting not to have the award of result.
