摘要:
黑河电网位于黑龙江电网北部末端,通过长距离线路及长链式结构与主网连接,同时承担着 俄罗斯电力受入。系统短路容量较低,输电功率波动较大,沿线电压呈中间高、两端低变化趋势,且压 差较大。500 kV 安北变的建设进一步增加了长链式电网长度,导致系统无功电压控制更加困难。本文 从工程运行实际出发,综合考虑正常、检修、充电及附加一重故障等多种运行方式需要,提出长距离、 长链式、弱系统无功配置优化原则、流程、方法,并对安北500 kV 输变电工程进行无功配置方案优化。
Abstract:
Heihe power grid is located in the end of north Heilongjiang power grid and is connected to the main grid through a long line and long chain structure and,at the same time,is responsible for the Russian power injection. The short circuit capacity of this system is low while the transmission power fluctuation is large. The voltage along the line shows such trend as low on the both ends but high in the middle and the difference of voltage is high. The construction of 500 kV Anbei station increases length of long?chain grid further,causing the reactive voltage of the system more difficult to be controlled. In this paper,starting from the actual operation and with comprehensive consideration of the need of multiple operation mode such as normality,maintenance,charge and a heavy fault,the principle,process and method of reactive power opti? mization of long distance,long?chain and weak system are proposed. And the reactive optimization plan of Anbei 500 kV power transmission and transformation project is optimized.
