摘要
为保证电力系统的调度效果,实现电力系统智能化管控,设计基于PID控制技术的电力系统运行自动化控制系统.系统的基础层通过数据采集设备采集电力系统运行状态数据,通过通信接口将其传送至数据层;数据层依据数据分层传输结构和数字签名机制,存储以及调度接收的数据;控制层调用数据层中的数据,利用模糊级联PID控制器完成电力系统运行自动化控制,并向基础层的现场控制器下达协调控制指令,实现电力系统现场控制,并回传控制结果.测试结果显示,该系统的数据调度能力较好,RPS系数结果均在0.942以上,电力系统运行的失效率和修复率均在92.7％以上,绝对误差积分结果均在0.025以下,控制响应能力较好.
Abstract
In order to ensure the scheduling effect of the power system and achieve intelligent control of the power system,a power system operation automation control system based on PID control technology is designed.The basic layer of the system collects the operating status data of the power system through data collection devices,and trans-mits it to the data layer through communication interfaces.The data layer stores and schedules the received data based on the hierarchical transmission structure and digital signature mechanism of the data.The control layer calls the data in the data layer,uses a fuzzy cascade PID controller to complete automatic control of power system opera-tion,and issues coordinated control instructions to the on-site controller of the basic layer to achieve on-site control of the power system,and return the control results.The test results show that the system has good data scheduling ability,and the RPS coefficient results are all above 0.942,the failure rate and repair rate of the power system oper-ation are both above 92.7％,the absolute error integration results are all below 0.025,good control response ability.
