【摘要】：为减轻操作人员劳动强度,提高电力系统运行的可靠性和高效性,提升整个电网的自动化水平,国家电网公司提出建设“智能电网”的号召。为响应这一号召,提升配电网网络的管理水平,改善电力用户对电能质量和可靠性的使用效能,纠正原有配电网络的落后局面,全国各地区应当不断推进配电网发展,做好智能配电网的建设管理工作,为智能电网的建成奠定基础。虽然杭州地区在配电网自动化改造过程中走在全国前列,但在诸多方面仍有不足之处,应当不断借鉴国内外先进技术改善自身配电网自动化系统的性能。本文基于杭州电力公司配电网建设现状,有针对性地提出了杭州地区配电网网架提升方案,确定了配电网网架补强和一次设备提升改造原则和改造方式,分析明确了杭州地区配电网自动化建设的改造原则与改造内容;设计了基于信息交互总线的主站系统总体架构,从功能的总体框架出发确定了自动化改造方式,从网架结构、供电可靠性分析和平均故障停电时间等角度验证了所提改进方案的有效性。
[Abstract]:In order to reduce the labor intensity of operators, improve the reliability and efficiency of power system operation, and improve the automation level of the whole power grid, the State Grid Company proposed the call to build "smart grid". In order to respond to this call, improve the management level of the distribution network, improve the power quality and reliability of power users, and correct the backward situation of the original distribution network, all regions of the country should continue to promote the development of the distribution network. Do well the construction and management of smart distribution network, and lay the foundation for the establishment of smart grid. Although Hangzhou area is in the forefront of the whole country in the process of automatic transformation of distribution network, there are still some shortcomings in many aspects, so we should constantly use advanced technology at home and abroad for reference to improve the performance of our own distribution network automation system. Based on the present situation of distribution network construction in Hangzhou Electric Power Company, this paper puts forward the scheme of improving the distribution network structure in Hangzhou area, and determines the principle and mode of the upgrading of distribution network structure and primary equipment. The transformation principle and content of automation construction of distribution network in Hangzhou area are analyzed and defined, the general architecture of master station system based on information interactive bus is designed, the automatic transformation mode is determined from the overall frame of function, and the structure of grid frame is established. The reliability analysis and average outage time of power supply verify the effectiveness of the proposed scheme.
