【摘要】：针对就地化智能电子设备(IED)在开关场无防护安装时面临的接地及抗干扰问题,介绍了传统变电站二次等电位地网的设计及IED的接地方法。分析了就地化IED在开关场无防护安装时需要面对的复杂电磁兼容环境和需要解决的具体问题,提出了分布式开关场二次等电位地网的设计思路。详细阐述了就地化IED及其外部线缆在开关场无防护安装时的接地方法、就地化IED增强抗干扰能力的设计方法。厂内试验结果验证了所提方法的可行性。
[Abstract]:In view of the grounding and anti-interference problems faced by the local intelligent electronic equipment (IED) in the unprotected installation of the switching field, the design of the secondary equipotential ground grid of the traditional substation and the grounding method of the IED are introduced. This paper analyzes the complex EMC environment and the specific problems to be solved when the local IED is installed without protection in the switching field, and puts forward the design idea of the secondary equipotential ground network in the distributed switching field. The grounding method of the local IED and its external cable in the unprotected installation of the switch field is described in detail. The design method of the local IED to enhance the anti-interference ability is described in detail. The feasibility of the proposed method is verified by the in-plant test results.
