摘要
为适应高电压、大容量电网和市场经济迅速发展的需要,改变思维方式开发 ΔUJ 优化无功潮流程序,建立了区域无功平衡新概念,提出 AVC 的概念和实施 AVC 的新方法——集中控制型、分散控制型或混合型,离线计算 500 kV 湖南电网 2000 年后 6 种预测负荷方法下的 ΔUJ 优化无功潮流。计算结果表明方法科学、简单,适用于 110 kV 及以上电压等级的电网。
:This paper introduces the optimal reactive power flow program with new concept of economical voltage difference (ΔUJ). The new method for implementing AVC, centralized, distributed and hybrid control, is presented, and the new concept of balancing reactive power in region is established. Off-line calculations of ΔUJ optimal reactive power flow in six forecasting load modes for 500 kV power network in Hunan are performed, which shows that the new method is simple and suitable for 110 kV and above power networks.
