Design and Optimization on Converter Station Compound Grounding Grid in High Soil Resistivity Area
摘要
Abstract
Grounding grids designed by conventional methods can not satisfy requirement for limit value of grounding resistance of relevant regulations in those high soil resistivity areas, therefore, this paper introduces design methods for compound grounding grids by taking Luxi converter station in high soil resistivity area for an example, and studies influence of different design objectives by respectively taking restrict and loose limit value conditions for grounding resistance.It also presents corresponding design optimization schemes, adopts grounding analysis software CDEGS to check security of designed compound grounding grids and verifies related security and feasibility.关键词
