摘    要:阐述了利用安全约束调度进行自动发电控制(AGC)安全约束控制的实现技术及应用。当系统处于紧急状态或预警状态时,AGC根据实时安全约束调度提出的机组调整方案和灵敏度信息,通过限制机组AGC调节上下限或限制机组AGC调节方向,执行稳定断面越限的校正控制和预防控制。实践表明,AGC安全约束控制可有效消除和缓解了电网稳定断面的越限,提高电网的安全稳定水平。

关 键 词:自动发电控制  安全约束  校正控制  预防控制

Abstract:The technology and application of Automatic Generation Control (AGC) security constraints control which takesadvantage of security constrained dispatch are d'escribed in this paper. When the system is in a state of emergency or warning status, AGC performs the corrective and preventive control of stable cross section limit in use of restricting units of AGC to adjust the upper and lower limits or direction based on unit adjustment programs and sensitivity information proposed by the real-time security constrained dispatch. The results show that the AGC security constraints control can effectively eliminate and mitigate the limit of grid stability section, and increase the level of grid security and stability.
Keywords:Automatic Generation Control  security constraints  corrective control  preventive control
