Research On The Programme And Operation Of 20kV Voltage Distribution Network In Jiangdong Area Of Hangzhou

In recent years,the construction of Hangzhou is developing.Jiangdong area as the focus of reform and development in Hangzhou should be built reasonably.It is very important for the economic development of Hangzhou to reform the distribution network and provide safe,reliable,high-quality electrical energy.This study analyzes the current situation of power grid in Jiangdong area,including: the analysis of 220/110/35 k V substation,the present situation of medium voltage distribution network,the basic situation of switch,the analysis of operational indicators.And then digging out the weak links of high and medium voltage distribution network in jiangdong area.In addition,the elasticity method and the saturation load forecasting method are combined to determine the load forecasting results in Jiangdong area.Based on the analysis of load forecasting results in jiangdong area,the most reasonable and reliable scheme for the distribution network is developed,and the practical operation analysis of 20 k V distribution network planning is carried out.The feasibility and superiority are verified in detail.Big Jiangdong town in medium voltage distribution network with 20 k V voltage,not only to achieve the quality standards for power supply,but also saves the corridors,quickly determine the medium channel,convenient maintenance operation,greatly reduces the cost of power supply,and pointed out the direction for the construction of a new era of big Jiangdong area distribution network.
