| 广域保护系统(WAPS)能利用电力系统的广域信息而不局限于当地信息进行系统保护,从而可达到更好的保护性能。介绍了WAPS的优点和研究现状,重点探讨WAPS的结构和通信问题。通过借鉴数据采集与监控(SCADA)系统的3代结构形式,分析和总结了WAPS所能采取的3种结构形式(集中式、分布式和网络式)的特点和性能,认为网络式结构比集中式、分布式结构更加灵活和可靠,更加适合广域保护的要求。利用OPNET软件对WAPS的网络式结构进行建模和仿真,分析和比较了不同网络的通信延时,同时为了适应突发数据的传输建议采用100 M以太网。 |

| Abstract: |
| WAPS(Wide-Area Protection System) utilizes global information to realize system protection instead of local information to achieve better protection performance.Its advantages and research achievements are introduced and its architecture and communication network investigated.Referring to the three generations of SCADA system,the features of three architectures(centralized,distributed and networked) for WAPS are discussed in detail.The networked architecture is considered to be more flexible,reliable and suitable for wide-area protection than the others.The networked WAPS is modeled and simulated based on OPNET simulator.The communication delays of different communication networks are compared and it is suggested to use 100 M Ethernet to deal with burst data transmission. |
