摘要
研究粤北电网在环网运行和解环运行方式下的安全稳定控制策略。在环网方式下采取"最小过切原则"决定切机量,在解环运行方式下采取"最小欠切原则"决定切机量,有效地提高了粤北电网向主网送电的稳定性和可靠性。新策略不仅能够应对正常运行方式和各种检修运行方式,还能够适应粤北220kV电网的改造和发展。
The research on the safety-stability control strategies for Northern Guangdong Power Grid in both closed-loop and opened-loop operations is carried out. A new control strategy is proposed that ＂the principle of minimum over-tripping＂ is for the closed-loop case while ＂the principle of minimum lacking-tripping＂ is for the opened-loop case. This control strategy has effectively improved the stability and reliability of Northern Guangdong Power Grid. With this new strategy it is possible for the Grid to respond to various operation or maintenance cases, and to adapt to the transformation and development of its 220 kV level system.
