摘要
根据2015年春节期间的实际负荷和电网运行情况,探讨广西电网电压偏高越限问题。通过对广西电网春节期间无功电压现状以及电压调整原则分析,提出了广西电网无功调压的优化措施,并通过实际应用验证了优化措施的有效性。应用结果表明,加强电压监控、机组进相运行、投切无功补偿设备和停运线路减少系统充电功率等多种调压优化措施实现了无功功率分层分区平衡,同时也保证了电网安全稳定运行,提高了供电电能质量。
According to the actual load and power grid operation during the Spring Festival of 2015, the higher voltage and over limitation problem in Guangxi power grid are discussed. By analyzing the reactive power situation during the Spring Festival in Guangxi power grid and the voltage regulation principle, optimization measures for reactive power regulation in Guangxi power grid are proposed the effectiveness of which has been verified by the practical application. Application results show that multiple voltage regulation optimization measures including strengthening voltage monitoring and control, leading phase operation of generator, switching on/off reactive compensation device and line outage to reduce charging power of system and so on, has realized the hierarchical and regional balance of reactive power and at the same time guaranteed the security and stability operation of power grid and improved the power quality of power supply.
