Research on Active Interference Simulation Testing Technology of Distributed FA

馈线自动化动作逻辑正确与否是保证分布式FA系统可靠运行的关键,由于馈线自动化实施的复杂性和现场环境的不确定性,系统容易受现场终端之间的通信故障、开关拒动、开关慢动等多种干扰因素的影响,如何对其动作逻辑进行测试验证一直是制约配电自动化实用化的关键因素之一。文中研究了分布式FA主动干扰仿真测试技术,介绍了测试原理,描述了主动干扰模拟实现的过程,且测试时能够自动生成测试报告。最后,以一个典型的电缆网络为例进行了仿真测试,并详细分析了测试的过程,实现了干扰发生时分布式FA系统动作逻辑正确性的验证。

The correctness of feeder automation operation logic is the key to ensure the distributed FA system operation reliably. Due to the uncertainty of field environment and the complexity in FA implementation,the system is easy to be affected by various kinds of interference factors,including communication failures between site terminal unit,switch refusing action or action slowly,and so on,and the method to verify its operation logic has all along been one of the key restraining factors for distribution practically. An active interference simulation testing technology of distributed FA is studied and created in this paper. The testing principle is introduced,the process of active interference simulation and realization are described,and the testing report can be generated automatically. Finally,taking a typical cable network as an example,simulation testing is carried out,and the process of the simulation testing is analyzed in detail,realizing the verification on the operation logic of the distributed FA system.
