摘要
远程控制已成为确保电力系统安全稳定运行的重要技术手段,IEC61850对电力设备的远程控制提出了更高的要求。以增强安全的操作前选择控制的有限状态机为基础,提出了基于IEC61850的电力远动系统的远程控制模型。结合实际应用的需要,设计了基于IEC61850的远方控制接口,实现了对智能电子设备(IED)的远程访问控制,对断路器进行了断开与闭合操作。基于上述研究所开发的系统通过了在某地区电网进行的工业现场试验并试运行,验证了模型的正确性和方案的可行性。
The remote control of electric power equipment is an important approach to solving the problem of safety and steady operation of the power grid. IEC 61850 makes a new requirement on remote control for electric power equipment. Based on an analysis of the finite state machine of select before operate （SBO） with enhanced security, a new remote control model for power telecontrol system is proposed on the basis of IEC 61850. Moreover, considering the actual needs of the power telecontrol system, a telecontrol interface based on IEC 61850 is designed to control the intelligent electronic device and to open or close the circuit breakers. A prototype system based on the above-mentioned methods has been developed and gone through field-testing and trial operation in a subtransmission network, which proves that the models and methods proposed are satisfactory and feasible.
