GPRS通信技术在配电网中的应用

随着国家城市、农村电网改造的不断深入,进行配电网自动化系统建设是必由之路,而自动化系统建设和完善的重要前提就是要保证通信的实时畅通。该论文根据配电自动化系统对通信在数据传输能力、可靠性、安全性、实时性、经济性及易于运行维护等方面的要求,全面分析现行配电自动化中的各种通信方式,并对各通信方式的适用范围进行比较和讨论,剖析各自存在的问题,对GPRS相关关键技术进行分析,着重分析涉及GPRS的网络结构、协议模型、安全性及应用范围,提出将GPRS技术应用在配电自动化系统中解决通信传输问题的新模式,并就两种不同技术组网方案通过实例从可用性、适应性、可靠稳定性、数据安全性、经济性及运行维护便捷性六个方面进行深刻剖析,GPRS技术已成熟运用于公网,信号覆盖面广,延伸至电力专网具备很好的可行性,针对配网监测节点多而分布广、网络调整频繁的局面具备较强的适应性,从软硬件的配置上采取多重措施确保数据在GPRS网络上传输的可靠稳定性,在安全性方面提出附加主机和终端之间的直接认证技术,为主机和终端之间的通信提供高强度的安全保障。初步验证GPRS技术组网方案的可行性,为配电自动化发展提出新的思路。在保证配网数据传输的安全可靠性的前提下,作为市场经济大环境下的正在逐步推进电力体制改革的电力企业来说,以降低工程投资和减少运行维护工作量,提高生产效率作为电力企业不断发展,降低成本、提高效益的重要条件。因此,在配电网中应用GPRS通信技术将有助于实现电力企业的更快更好地发展。该论文也为进一步加大电力系统对开展GPRS技术的关注以及推动此项技术在电力系统配电自动化中的应用提供了借鉴。
