基于模糊自适应控制的接触器过零投切系统研究
Research of contactor zero switching systembased on fuzzy adaptive control
In this paper, research background is dynamic high voltage power reactive power compensation with load changes gently, play contactors advantage in high voltage field, For the issue of instant overvoltage and surge current when contactor switch capacitor. Proposed zero-crossing switching synchronization closing control. Through the analysis of the dynamic characteristics of the contactor, Designing the vacuum contactor control system, testing the response time of the contactor. Summarizing the response time of contactor based on operating voltage and ambient temperature. Proposed fuzzy adaptive control for the contactor response time with different ambient temperatures and operating voltage. Guaranteeing the time of switched within 1ms when capacitor voltage and current control in near zero. Making the corresponding simulation and experimental verification, achieved good results. The research can effectively control the adverse effect of the surge current and voltage flicker when switching instantly. Ensure the power grid safe and stable operating with Satisfying the conditions of reactive power compensation system
