摘要

为解决加速器电源因电网电压陷落导致电源输出电流突变问题，提出一种基于磁铁负载侧的动态电流补偿方法，该方法以并联方式在负载端进行电流补偿。本文对其原理进行了可行性分析，用带通滤波器提取突变波形并实时计算通过比例积分（Proportional Integral，PI）控制产生反向突变电流以达到抑制的效果，并通过了原理性仿真以及样机验证。从实验结果验证了方案的合理性，补偿电流的响应速度能够跟上突变电流，对于突变电流确实有明显的抑制效果。

Abstract

Background

Shanghai Synchrotron Radiation Facility (SSRF) is an advanced third-generation synchrotron radiation electron accelerator

it requires the magnetic field of long-term stability and high-accuracy. Hence the accelerator power supply is requested to keep the exciting current stable.

Purpose

This study aims to propose a dynamic current compensating method based on the load side of magnet to solve the problem of abrupt current caused by power grid voltage drop.

Methods

Band-pass filter was applied to the extraction of the abrupt current waveform

and the opposite polarity with the abrupt current was generated by real-time computation of the proportional integral (PI) controller. The compensator compensates the abrupt current by paralleling this opposite polarity current to inhibit the abrupt current at load side.

Results

Simulation and experiment results showed that the above-mentioned method has obvious effect for inhibition of abrupt current on load side.

Conclusion

The compensator is proved to be practical in restraining abrupt current.
