摘要

新型电力系统的架构将极大地增加其运行和控制的难度和脆弱性.信息与通信技术(ICT)的高度集成有利于实现充分的信息共享,但也使得建立基于ICT的电力二次系统建模分析需求更为紧迫.本文首次提出实现信息共享和互联互通互操作准则的电力二次系统仿真建模方法.以功能描述复杂的智能变电站二次系统为研究对象,首先提出契合智能电子设备(IED)互联互通需求的结构模型;然后,进一步提出带电力系统二次业务内置算法的IED功能模型,以及符合IEC 61850标准互操作需求的电力通信协议模型;其次,通过进程域的状态设计,实现节点域的IED功能以及网络域的IED之间数据交互.最后,以典型220 kV智能变电站的线路电流保护为例,关联电力一次系统运行状态仿真实现电力二次系统继电保护定值修改以及故障后保护动作全流程,验证了所提仿真模型的正确性.

Abstract

New power system achitecture will greatly increase the difficulty and vulnerability of the operation and control of power systems. The high integration of information and communication technology (ICT) promotes comprehensive information sharing, but it also highlights the urgency of establishing modeling and analysis methods for ICT-based power secondary systems. In this paper, simulation modeling methods for power secondary systems are proposed for the first time to achieve information sharing under interconnectivity and interoperability criteria. A smart substation secondary system with complex functional descriptions is taken as the research object. First, a structural model of intelligent electronic devices (IEDs) is proposed which meets the interconnectivity requirements. Then, a functional model of IEDs with built-in algorithms for secondary business in power systems is proposed, as well as power communication protocol models which meet the interoperability requirements under IEC 61850 standard. Furthermore, the IED function in the node domain and data exchange between IEDs in the network domain are achieved, through the state design in the process domain. Finally, taking a typical 220 kV substation line current protection as an example, the entire process of protection setting modification and protection actions after a fault occurs are simulated by correlating the operating status of the power primary system, verifying the correctness of the proposed simulation models.

Key words： new power system; information and communication technology (ICT); power secondary system; finite state machine; intelligent electronic device (IED)
