Abstract

Load frequency control (LFC) is a very important component in power system operation and control for supplying sufficient and reliable electric power with high quality. To ensure satisfactory area frequency and inter-area tie-line power is one of the main requirements for the LFC. This paper presents a multi-functional fuzzy logic based tie-line bias control (TBC) scheme considering the MWh constraint for the power transmission on the tie-line and the regulation margin. In addition, the real power flow constraint on each trunk line is also taken into account. A detailed nonlinear LFC simulator has been developed in the Matlab/Simulink environment. Simulation results demonstrate the efficiency of both the proposed control scheme and the simulator performance.

基于模糊逻辑的多功能负载频率控制
负荷频率控制是电力系统运行控制的重要组成部分,是保证电力系统提供充足、可靠、高质量电力的重要手段。保证满意的区域频率和区域间接线功率是LFC的主要要求之一。本文提出了一种基于模糊逻辑的多功能联络线偏置控制方案,该方案考虑了联络线输电的兆瓦时约束和调节余量。此外,还考虑了各干线上的实际潮流约束。在Matlab/Simulink环境下开发了一个详细的非线性LFC仿真器。仿真结果证明了所提控制方案的有效性和模拟器的性能。
