Electrical System Design Of Changchun Southeast Thermal Power Plant

In this paper, the object of study for the southeast thermal power plant in Changchun, the power plant for thermal power plants, the scale of 350 units of two MW coal-fired cogeneration unit.According to the results of power balance Changchun regional power balance, power balance and 220 k V layer Changchun area southeast of Changchun area that has power in Southeast Changchun, this project is completed and put into operation will become one of the main power supply of power grid in the southeastern region of Changchun, is a system in a regional power plant, to meet the needs of safe load the power supply is stable Changchun regional power grid and Changchun area growth.This paper from the view of the electric design Changchun southeast thermoelectric power plant, in accordance with the construction of "resource conserving and environment friendly society", discusses the system scheme of the electric power plant, and focus on the application of new technology and new products for data comparison and cost analysis, in order to get a same level of unit advanced design.In this paper, the electrical part of the power plant design, the two design, lighting design,and other aspects of the electrical part of the various aspects of the design are described.In addition to the conventional "plate" of the thermal power plant in Changchun, South East thermal power plant each electrical system design. Focus on the 220 k V switch with GIS or open field layout scheme selection, choose the most suitable, the highest economic benefit, the most safe operation scheme for this project, in the premise of satisfying the technical requirement, save project investment; research on electronic controlled ECMS and DCS separation system layout scheme, the implementation of the new the application of new technologies, in this project, through in-depth analysis of application of ECMS system in power plant, not only can improve the level of the power plant, but also save investment, improve the information collection module and digital; of container type diesel engine and diesel engine room research, analysis of container type diesel engine used in the feasibility the power plant and the northeast region and safety; research on insulating tube bus to the equipment, through the research of this paper, the equipment in the power level Application in factory.Through a series of work in the paper, not only for the conventional design can save investment, optimize the level of thermal power plant, to improve the operation reliability of the power plant and new technology application level; according to the papers on the electrical system, power rate Changchun southeast thermoelectric power plant factory has been reduced,the level of plant the transformer capacity decreases, the transformer load loss is well controlled,full response to the national "building a resource conserving and environment-friendly society" policy.Changchun southeast thermal power plant construction project in the Changchun area of the entire power grid occupies a very important position. In this paper, through the analysis of the electrical part of the project design, project selection and other aspects, the use of cost calculation, statistics, performance comparison, equipment characteristics comparison and combined with the engineering characteristics of this project, the important equipment,mentioned on the front of the main technology node for the analysis, in order to get cogeneration a generator scheme is reasonable and feasible, efficient, environmentally friendly,achieve optimal performance, the project leader.
