Research on Intelligent Frequency Regulation Capability Evaluation Technology for Coal-Fired Units Based on Autonomous Controllable PLC

Abstract The generation frequency of grid-connected units determines the power supply reliability grid and primary regulation, as first guarantee to stabilize is affected by category generating operation mode lacks systematic real-time optimization monitoring means. This paper takes a 300MW sub-critical heating unit research object, researches, analyzes three aspects signal homologation, multi-dimensional optimization, intelligent decision-making establish evaluation model regulation capability unit. accuracy assessment reaches 83%, develops control platform based on autonomous controllable PLC, realizes dynamic replacement traditional technology means, also improves qualification rate about 23.2%.
