互联电网AGC分层控制与CPS控制策略

HIERARCHICAL AGC MODE AND CPS CONTROL STRATEGY FOR INTERCONNECTED POWER SYSTEMS

通过分析网调和所辖各省调构成的中国互联电网的特点,提出了基于联络线和频率偏差控制(TBC)模式下的网省调自动发电控制(AGC)分层控制与协调技术;重点讨论了CPS考核标准下新的AGC控制策略。这些处理方法有利于提高电网频率控制质量,并体现在紧急情况下各AGC控制区域之间的相互支援,在多个网省调的实际应用中取得了良好的效果。

Based on the analysis of the interconnected power systems in China, hierarchical tie-line bias control (TEC) mode and CPS control strategy, which is a new control strategy to perform automatic generation control (AGC) and its assessments by the NERC Control Performance Standard (CPS), are proposed in this paper. These schemes have been implemented in the energy management system (EMS) of several large power systems in China. It has been shown that they are practical and valid to co-ordinate multi-areas AGC and improve frequency quality.
