摘要
在单装置Petri网(PN)模型的基础上,提出了一种面向对象的输电网线路保护Petri网模型。该模型考虑了继电保护装置、断路器装置、重合闸装置间的配合关系,并利用面向对象技术降低了单个PN仿真单元的复杂性。为仿真多个保护装置间的配合关系,构建了时间决策单元和故障计算单元。时间决策单元可处理不同保护间的时间配合关系,故障计算单元通过与仿真单元的消息传递模拟保护动作过程。对某输电网线路保护进行仿真,结果验证了模型的有效性。
Based on the single PN（Petri Net） model,an object-oriented line protection PN model is proposed for power transmission network,which considers the cooperation among relay protection,circuit breaker and reclosing device,and applies the object-oriented technology to simplify the PN simulation unit. The time decision-making unit and the fault calculation unit are established to simulate the cooperation among protections. The former handles the time cooperation among protections and the latter transfers the message to the simulation unit to simulate the operating process of protection. The simulative results for the line protections of a power transmission network demonstrate the effectiveness of the proposed model.
