摘要：

星点高压电源是为中国环流器二号A装置的辅助加热系统提供高压的一套重要高压电源,为保证星点高压电源控制系统稳定运行,在分析干扰源产生、分类及作用机理的基础上,从硬件和软件两方面对测量控制系统进行抗干扰设计。硬件方面主要是通过改善电源、滤波处理、接地等方面采取措施,软件则是采用多种数字滤波相结合的方法减少干扰。实践证明:适当的抗干扰设计确实能增强控制系统的可靠性,提高星点高压电源的控制精度。

Abstract: The neutral-point high-voltage power supply is an important HV power supply for the auxiliary heating system on HL-2A Tokamak. To ensure stability of the control system, anti-jamming design in hardware and software was achieved after analyzing production, classification and action mechanism of jam source. In the aspect of hardware, an electronic power module was used to restrain power jam, some filtering and earthing methods were used in the system. In the aspect of software, some soft filtering arithmetic methods were used in the program. Experimental results proved the good controlling properties and reliable protective properties of the control system.

Keywords: HV power supply; control system; anti-jamming; electromagnetic compatibility
