摘要
高压钠灯点亮后适当降低并稳定其电源电压是最常见的隧道节能方式。介绍高压钠灯的特点,比较和分析照明回路3种电压调节技术,依据规范和实际情况确定高压钠灯的降压目标值,提出一种基于模糊PID的调压控制算法。仿真试验和实际数据表明节电率达到35%~45%,具有一定应用价值。
Appropriate reduction and stabilization of power supply voltage after HV sodium lamps light up is a most common tunnel energy-saving mode. This paper introduces the features of HV sodium lamps,compares and analyzes 3 voltage regulating techniques for lighting circuit,and proposes a voltage regulating control algorithm based in fuzzy PID in accordance with the target value of voltage reduction of HV sodium lamps determined pursuant to the specification and actual conditions. The simulation test and actual data show that the fuzzy PID control reaches 35% ~ 45% power-saving rate and exhibits a certain value of application.
