广域电力系统的量化输出反馈控制

Quantized Output Feedback Control of Wide Area Power System

采用量化器将测量输出数据进行量化,用于解决数据存储空间不足以及通信拥塞问题,便于系统扩展和监控。设计了基于观测器的量化输出反馈控制器,保证系统稳定性且改善系统的动态性能。通过电力系统仿真实验验证了该方法的有效性。

In this paper,a quantizer is introduced to quantize the measurement outputs to solve data storage space and network congestion.It is also convenient for system expansion and supervision.Then,the observer-based quantized output feedback controller is designed to ensure the stability of the system and to improve the system dynamic performance.Finally,a four-machine two-area power system is given to demonstrate the effectiveness of the proposed method.
