Lighting Reliability Optimization Strategy for Primary Frequency Regulation in Thermal Power Generation
WU Wangang
Abstract：Frequency fluctuations during primary frequency regulation of thermal power units significantly impact the reliability of on-site lighting systems.Through an analytical study of the lighting system in a 660MW ultra-supercritical unit,a frequency-lighting coupling mechanism model was established,and a comprehensive regulation scheme based on adaptive parameter optimization was designed.Test data indicate that when frequency deviation exceeds±0.1Hz,voltage fluctuations in the lighting system increase by 15%,and the failure probability of LED drive devices rises by 8%.After implementing the optimization scheme,lighting system reliability improved by 12%,equipment failure rates decreased by 18%,and annual operational and maintenance costs were reduced by 250,000 yuan.This research provides technical references for enhancing the operational reliability of lighting systems in thermal power plants.
