摘要

保护继电器是用来保护电力系统的。对继电器的主要要求是选择性、可靠性和速度。差动继电器是所有类型的继电器中最可靠的一种，它以测量电流和继电器之间的信息交换为基础。提出了采用无线通信技术实现差动继电器中的信息交换。基于中继间通信网络，提出了一种包含二次中继的广义差动中继方案。利用Petri网的数学工具对基于无线通信的差分中继方案进行建模。在Petri网建模的基础上，研究了以系统可靠性最大化为目标的无线通信网络资源分配问题。数值仿真验证了所提中继方案的有效性。

Wireless communication aided differential relay protection in smart grids: A concerted blitzkrieg

Protective relay is used to protect power systems. The main requirements on protective relays are selectivity, reliability and speed. Differential relay, which is based on the measurements of currents and the exchange of messages among relays, is the most reliable one among all types of protective relays. Wireless communication is proposed for the information exchange in the differential relay. Based on the communication network among relays, a generalized differential relay scheme is proposed to incorporate secondary relays. The mathematical tool of Petri net is used to model the wireless communication based differential relay scheme. The problem of resource allocation for the wireless communication network is studied in order to maximize the system reliability, based on the Petri net modeling. Numerical simulations have demonstrated the validity of the proposed relay scheme.
