摘要
讨论以单片机为控制核心的自动阻抗式配电自动化开关系统,目的是验证和进一步提高继电器的自动化性能。论述阻抗距离保护的基本原理,分析阻抗式自动化开关控制器的构成和基本功能,提出阻抗式自动化保护开关在实际应用中的模型,并实际仿真模型故障后的电压电流变化,从而验证了原理算法的正确性。进而能够较好地解决贯通线自动化改造的现实问题。
It was discussed the auto-impedance distribution automation system switch, which controlled by MCU. The purpose was to validate and further improve the automation of the relay performance. It put out the basic principles. It was analyzed the impedance-automation switch controller of the basic structure and function. It also put out the impedance-made automatic protection switching in the practical application model. And in order to verify the correctness of the principle of algorithm, It was actually simulated the model after the failure of the current and voltage changes. And it could get a good continuous power transmission line of the reality of the problem.
