摘要

电力系统的负荷变化是不可预测的,导致频率和电压偏离其标称值,导致由于线路跳闸甚至停电而造成的发电损失。通过自动发电控制,频率和电压漂移可以最小化并保持在可容忍的范围内。自动发电控制系统由两部分组成;负载频率控制(LFC)和自动电压调节器(AVR)。本文通过在SIMULINK中建立模型,对负载频率控制器的工作原理进行了仿真研究。仿真研究有助于学生了解负载频率控制器的原理和挑战。

Simulation Study of Load Frequency Control of Single and Two Area Systems
The load variation on a power system being unpredictable causes drifts in frequency and voltage from their nominal values resulting in loss of generation due to tripping of lines and even blackouts. Frequency and voltage drifts can be minimized and kept within tolerable limits by automatic generation control. Automatic generation control of a system consists of two parts; load frequency control (LFC) and automatic voltage regulator (AVR). In this paper, a simulation study is carried out to understand the operation of load frequency controller by developing models in SIMULINK. The simulation study helps students to understand the principle and challenges behind load frequency controller.
