Intelligent control technology of substation lighting system based on PLC
The lighting system of substations is an essential component for ensuring the safe operation of power equipment and the occupational safety of maintenance personnel.To address issues such as low energy consumption control efficiency,unstable lighting quality,and lagging management levels in substation lighting systems,this study designs an intelligent lighting control system based on Programmable Logic Controller(PLC).The system uses Siemens S7-1200 PLC as its control core and implements functions such as automatic illuminance adjustment and scene mode control through a control strategy combining fuzzy PID with weather compensation.The practical application at the 110 kV Wengmei Substation in Hangzhou demonstrates that the system achieves illuminance control accuracy of±15 lx,improves lighting uniformity to 0.86,and reduces energy consumption by 32.5%compared to traditional systems.The research results provide a scalable technical solution for the intelligent upgrade of substation lighting systems.
