摘要
【目的】
2
围绕建设具有中国特色国际领先的能源互联网企业战略目标，按照促进先进信息通信技术与先进能源技术深度融合应用，着力提升电力通信网对电网安全运行支撑保障能力的总体要求，苏州电力自2019年起规划建设220 kV保护专用通信网。目前苏州地区220 kV继电保护通道存在抢修时间较长、通信柜位资源占用较多、保护业务和通信业务混合组网等问题，对电网安全运行构成隐患。
【方法】
2
文章分析了苏州地区220 kV继电保护通道现状及存在的问题，结合苏州市光通信网络实际情况，提出了采用2 Mbit/s光接口直连保护设备的方式承载继电保护B口通道，并细化了电源改造方案、组网模式、保护业务承载模式和网络管理承载模式。
【结果】
2
苏州电力通过定制与继电保护业务匹配的小型专用通信传输设备，利用光纤直达通道和保护专用通信网复用通道的各自特点，建设了一张覆盖所有具有220 kV出线站点的保护专用通信网。
【结论】
2
保护专用通信网接入集中传输设备的网管监控继电保护通道，实现了继电保护通道的可观性和可测性，具有故障快速定位、故障隔离和通道迂回等优势，全面提升了继电保护通道的可靠性、独立性、灵活性和运维便利性，取得了显著的应用成效及创新成果，同时，为保护通道“3路由”应用做出了有益的探索。
Abstract
【Objective】
2
Focusing on the strategic goal of building an internationally leading energy Internet enterprise with Chinese characteristics
in accordance with the promotion of the deep integration and application of advanced information and communication technologies and advanced energy technologies
and focusing on the overall requirements of improving the power communication network to support and guarantee the safe operation of the power grid
Suzhou Electric Power launched the construction of a 220 kV protection private communication network since 2019. There exist problems with the 220 kV relay protection channel in Suzhou
such as long repair time
high occupancy of communication cabinet resources
and mixed networking of protection and communication services
which pose hidden dangers to the safe operation of the power grid.
【Methods】
2
This paper analyzes the current status and existing problems of Suzhou 220 kV relay protection channel. Combined with the actual situation of optical communication network in Suzhou
this paper proposes using 2 Mbit/s optical interface to directly connect protection equipment for carrying the relay protection channel of B port
and refines the power transformation plan
networking mode
protection business bearing mode
and network management bearing mode.
【Results】
2
Utilizing the respective characteristics of the direct channels with fiber optic and the multiplexing channels with protection private communication network
Suzhou Electric Power has built a protection private communication network which covers all transformer substations owning 220 kV outlets by customizing the small private communication transmission equipment that matches relay protection services.
【Conclusion】
2
The protection private communication network accessing to the centralized transmission equipment network management could monitor relay protection channels and achieve the observability and testability of the relay protection channels. It has advantages such as rapid failure positioning
failure isolation
and channel detour and comprehensively improves the reliability
independence
flexibility
and operation convenience of the relay protection channels. The protection private communication network has achieved significant application results and innovative results
which is also a beneficial exploration for the application of " 3 routes" for the protect channels.
