Research On The Reforming And Evaluation Of Medium Voltage Distribution Network Automation Of K City

K city is located in the eastern city of Tongliao in southern Inner Mongolia, a period of time in the future, focus on accelerating the development of the industry, the focus of industrial development is to promote the new industrialization, the main way to promote the development of the initiative to undertake the transfer of industries, the development of non-resource industries. Focus on the cultivation of the six major industries, to build four major bases, and gradually realize the diversification of the purpose of the three industry development pillar industry of a new type of traditional industries, new industries, the scale. The next area load density and higher position, K city stage grid size is very small, but the development of faster, therefore, how to use the opportunity of development areas, innovation of power supply technology, solve the problem of the development of power system, is of great theoretical and practical significance. In this paper, through the analysis of the history and current situation of power grid G town area, the objective and the principle of high voltage power grid planning and construction, through the study of the distribution automation scheme.In this paper, through the analysis of the history and current situation of power grid G town area, the medium voltage power grid planning and construction objectives and principles, through the study of the scheme of medium voltage distribution network.Based on a grid of G town within the substation and a transformation of the equipment, load forecasting, power distribution terminal construction and transformation as well as the communication system construction, combining with the planning results, in order to achieve G area current grid phase voltage, phase current, line voltage, line current, closed high voltage switch real-time acquisition, control of active power the parameters such as the communication and disconnection, fault alarm, data storage, information communication and other functions, the medium voltage distribution network planning project.
