智能变电站二次系统通用测试平台方案

提出了一种结构灵活、功能可配的智能变电站二次系统通用测试平台方案。通过双向接口整合动态模拟、数字仿真等系统资源，建立不同电压等级变电站一次系统模型、设备运行环境。通过配置文件、物理设备构建智能变电站系统级通用平台，可以实现在智能变电站系统环境下对继电保护、时钟同步系统、网络架构、高级应用等对象的闭环测试。建设的通用测试平台在事故反演与分析、工程调试，尤其是在国家电网公司二次设备入网检测工作中发挥了重要作用，具有较好的创新性与较强的实用性。

Unified test platform for smart substation secondary system

A unified test platform scheme with flexible structure and configurable function is presented. The primary system model and environment of which equipment runs with different voltage levels are constructed by integrating physical and digital simulation system, etc. through bi-directional interface. The unified system-level test platform for smart substation is also launched by employing configured file and physical device, by which the requirements for closed-loop test can be achieved for relay protection, time synchronization system, network architecture and advanced applications, etc. The platform plays a key role in fault replay and analysis, project debugging, especially in the verification test of secondary device for State Grid Corporation of China. The result shows the better innovation and strong practical.
