同塔多回线路感应电压的电路模型与有限元模型的计算及分析
Calculation and Analysis on Circuit Model and Finite Element Model of Induced Voltage of Multi-circuit Transmission Lines on the Same Tower
摘要
Abstract
Equivalent circuit method is generally used to calculate induced voltage value and induced current value of multi-circuit transmission lines on the same tower at present.Even if using software such as ATP-EMTP and PSCAD/EMTDC for analyzing, the calculated values are greatly different from actual measuring values due to models of the above software are based on two-dimension transmission line theory which is not in conformity with actual situations of substations.Therefore, it causes difficulties in selecting types for grounding switches.Thus, this paper makes a 3D model for Rongjiang substation and adopts finite element method to calculate electrostatic induced voltage value in the state of cold standby of transmission lines.It also analyzes influence of electric equipment in the substation on induced voltage value of lines and compares the calculated value with actual measuring value.Result verifies accuracy of this method.关键词
