摘要
Abstract
Based on two port equivalent circuit,an accurate calculation method for induced voltage and current of overhaul circuit is presented at the time of overhaul for one circuit or multi-circuit line of the multi-circuit power transmission line on the same tower. Two port equivalent circuits of power transmission line,series impedance and series conductance are estab-lished,and equivalent parameters of multiple two port equivalent circuits after series parallel connection are deduced as well. Specific steps and method for calculating induced voltage and current are proposed afterwards. This method can overcome shortages of traditional method such as low calculation precision,failure in comprehensively considering electromagnetic and electrostatic effects. Compared with PSCAD simulation examples,this method has higher calculation precision and its rele-vant conclusions have been applied in guiding practical projects.关键词
