Design On Electrical Primary System Retrofit For 2x300MW Project System Of Renqiu Power Plant

Being an important component part of the power grid,the power plant has important effect to the safe and reliable operation of the whole grid system,and shoulder the task of power plants and power users connect with each other,once the substation fault will inevitably affect the production and living.So its importance is no doubt.Electric power has more rapid development in recent years,the grid size is also growing,user requirement for the quality of power supply is becoming more and more high.Moreover due to the scarcity of land resources,the compactness of the construction of the transformer substation in electric power construction,practical put forward higher request,we need to at the beginning of the design should be considered.At the same time,the development of science and technology make the power plant or transformer substation continuously shortening the design period.We need to keep learning and exploring all of these factors,to seek a better design idea and design method of substation design more reasonable,to meet the increasing social demand.This thesis mainly according to the characteristics of the central China oil field power grid operation mode for Ren Qiu thermal power plant 2 * 300 mw electrical engineering to modify a system design.Paper first introduces the Ren Qiu 2 * 300 mw thermal power project construction necessity,then starting from site selection and economic analysis,mainly for power plant site selection,from the three aspects of hydrology,meteorology,geology analysis surrounding the site conditions,and gives some Suggestions to control the engineering cost.Then focus on the related link content specific design,a system involving the main electrical wiring design and the selection of transformer,the neutral point grounding way and reactive power compensation,short-circuit current calculation,conductor and the selection of equipment,auxiliary power bus and related electrical equipment selection and layout,and electrical equipment selection,the distribution equipment.The whole system design strictly comply with from the raw data of the power system,the relevant requirements,design principles and level so as to make system design more economic,reasonable and reliable operation.
