【摘要】：为了提高城市配网供电可靠性,其中一个重要的方法就是实现配电的自动化。在如今的科技趋势下,原有的传统配电系统很难达到现阶段的目标所希望的要求,因此,更先进的配电自动化系统就是现阶段智能电网发展的必然变革方向。为了更好的适应电网的发展趋势,以及更符合我国电网发展的实际要求,泰州市配电自动化系统的建设也就显得尤为重要。本文选取泰州医药高新技术产业开发区(中国医药城)作为前期建设区域,强化区域内系统一次网架,并通过建设配电自动化系统实现电网实时监控和故障自动处理,供电的质量和可靠性的有效提高;在对一次网架的现状分析基础上,提出了如联络开关等的方式来均衡负荷的改造方案,从而完善配电网的馈线自动化。通过分析配电自动化系统的需求,完成配电自动化系统全覆盖,实现三遥/二遥、配电SCADA,以及馈线自动化、潮流计算、拓扑分析等配电应用功能,达到配电调控一体化的要求。根据对配电网通信现状的分析,设计建设以光纤加无线的配网通信系统,实现区域通信全覆盖,对于区域关键节点采用光纤EPON通信方式,对于普通节点采用无线通信方式,通过合理的组网模式创新提升配电网通信的可靠性。
[Abstract]:In order to improve the reliability of power supply in urban distribution network, one of the important methods is to realize the automation of distribution. Under the trend of science and technology, it is difficult for the original traditional distribution system to meet the desired requirements of the present stage. Therefore, more advanced distribution automation system is the inevitable direction of transformation in the development of smart grid at the present stage. In order to better adapt to the development trend of power grid and meet the actual requirements of the development of power grid in China, the construction of distribution automation system in Taizhou City is particularly important. In this paper, Taizhou Pharmaceutical High-tech Industry Development Zone (China Medical City) is selected as the pre-construction area, and the system primary grid is strengthened, and the power grid real-time monitoring and automatic fault processing are realized through the construction of distribution automation system. The effective improvement of the quality and reliability of power supply; Based on the analysis of the present situation of the primary grid, a scheme of load balancing is proposed, such as the connection switch, so as to perfect the feeder automation of the distribution network. By analyzing the demand of the distribution automation system, the complete coverage of the distribution automation system is completed, and the functions of distribution application such as three-remote / second-remote, distribution SCADA, feeder automation, power flow calculation, topology analysis and so on are realized. To achieve the integration of distribution control requirements. Based on the analysis of the current situation of distribution network communication, a distribution network communication system based on optical fiber and wireless is designed and constructed to realize the full coverage of regional communication. For the key nodes in the region, the optical fiber EPON communication mode is used, and the wireless communication mode is used for the common node. The reliability of distribution network communication is improved through reasonable networking mode innovation.
