摘　　要：介绍基于 DSP 技术的无功补棱控制器,分析控制器的工作孱理。控制器用先进的过零触发电路,通过检测晶闸管无触点开关(SCR)两端电压为零作为 SCR 触发的必备条件,有硬件闭锁保护功能,实现了无功补偿控制器的高可靠性及自动化,有很强的现场控制和适应能力。A reactive power compensation controller based on DSP technolgy is presented in this paper.The working principles of this controller are also detailed.The controller contains an advanced zero-triggered circuit.This zero-trig- gered circuit detects the voltage across the contactless switch based on SCR and when the value of the detected voltage is equal to zero,the SCR is triggered.The controller provides a latched protection function.Therefore,the reactive pwoer compensation controller is accurate,stable and roboticized in operation.It possesses the powerfull ability of control and adapt in operation location.
