摘要: |
安徽500kV电网网损近年来有所增大,其原因主要有计量器的不精确、发电机所发无功功率过高和运行方式的不合理性。已对计量器校正或更换。针对发电机无功功率的控制,建议提高其运行的功率因数;针对运行方式的不合理性,应加强统一调度并由原先的电压和功率因数控制改为电压和无功功率控制,有效降低500kV电网网损。 |

Abstract: |
The active power loss of Anhui 500 kV network has increased in recent years.The reasons for it are imprecise measuring apparatus,overmatched reactive power of generator and irrational operating mode.The measuring apparatus have been rectified or replaced.To effectively lower the active power loss, the followings are suggested.To increase the operating power factor of generator for reactive power control and to strengthen the unified power dispatch and change the "voltage and power factor"control into"voltage and reactive power" control for operating mode improvement. |
Key words: network active power loss,economical operation,power factor |
