【摘要】:針對就地化智能電子設(shè)備(IED)在開關(guān)場無防護安裝時面臨的接地及抗干擾問題,介紹了傳統(tǒng)變電站二次等電位地網(wǎng)的設(shè)計及IED的接地方法。分析了就地化IED在開關(guān)場無防護安裝時需要面對的復雜電磁兼容環(huán)境和需要解決的具體問題,提出了分布式開關(guān)場二次等電位地網(wǎng)的設(shè)計思路。詳細闡述了就地化IED及其外部線纜在開關(guān)場無防護安裝時的接地方法、就地化IED增強抗干擾能力的設(shè)計方法。廠內(nèi)試驗結(jié)果驗證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.
