| Abstract: |
| Based on the structural characteristics of complex transmission lines on same tower and according to the demands of protective analysis，a suitable construction method of line simulation model with PSCAD as its core is proposed. The special software modules are established in the MATLAB environment to realize the automatic switching among different fault conditions and the control of PSCAD loop schedule while the preprocessing module of simulation data and the protective functional modules are designed，based on which，the operational characteristics simulation and analysis software for the relay protections of complex transmission lines on same tower is developed. Its validity and correctness are verified by the engineering applications. |
