摘要
根据复杂同塔线路的结构特点和保护分析要求,以PSCAD为核心,提出了一种适用于复杂同塔结构的线路仿真模型构建方法。基于MATLAB环境建立专用软件模块,实现故障条件自动切换及PSCAD软件的循环调度控制。对仿真数据预处理和保护功能模块进行了设计。基于上述工作,开发了一套复杂同塔线路保护动作特性分析软件。工程应用实例验证了该软件的有效性和正确性。
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.
