Substation Engineering, Modular Design And Research

With the setting-up and ripping of the electric enterprise's reform , market economic system, in order to develop continuously, we proposed higher demand to our design: Through optimizing the design plan, adopting advanced technology, reducing the cost of the project, design the up-market project for the owner, and this has became the goal that enterprises are pursuing. Especially with the development of society, the progress of technology, the improvement of equipment manufacture technological level and equipment dependability, the strengthening of environmental protection consciousness and land resource economization consciousness, the design revolution, modularization design and research of design has became inevitable.In this paper we discussed the 500kV, 220kV, 35kV distribution device, the optimization design of main transformer's fire-fighting system and put forward the module guidelines, overall thinking and working principle. And we also set up some model, such as 35kV distribution device module, protecting room module, etc.It's essence is to adopt advanced design philosophy, design method and means, form the alternate module and building module which will not change in one period, in order to benefit the designer carry on optimization grouping according to such concrete project conditions as its scale, topography , etc., and form the rational overall arrangement to fix up very fast.It's meaning purpose lies in it not merely helps to improve design efficiency that the module is designed, reduce the mistake of designing, shorten design cycle, and it is favorable to optimize overall arrangement of the transformer substation according to the technological process, improve the land utilization ratio of the transformer substation, reducethe construction area of the transformer substation, reduce the project expenses of the building construction, control the fabrication cost of the project. And it also help to improve the automatic level of the transformer substation at the same time, implement to nobody on duty, improve the operation safe reliability, economy and flexibility of the electric wire netting.The final goal of the module design and research in transformer project is developing a suit of software used in the whole design process of transformer project based on the module dividing and forming, helping the designer complete the design with high efficiency and high quality through calculating, analysing, transfering, making different design module up. This paper researches the module design, optimizes the design plan further in the hope of achieving the purpose that this will guide the transformer project design in the future.Through the design optimization and research in many projects, we finished the design of 500kV Qingdao and 220kV Fenghuang transformer substations successively, and make the remarkable effect. Now we are carrying on further research.
