Manzhouli Dongshan 10kV Scenery Complementary Power Station Design And Implementation

Wind energy and solar energy have good complementarity as renewable new energy sources.Rational development and use of them can be of great significance for solving the increasingly serious resource depletion and environmental pollution in the world today.Compared with photovoltaic or wind power generation alone,wind-solar hybrid power generation technology can effectively enhance the system's ability to adapt to weather changes,and make the system have better practical value.It can alleviate grid pressure,power peak shaving,and save traditional energy.It can play an important role,and the research of grid-connected wind-solar hybrid power generation system has important economic and social value.This project combines the actual construction project of Manshanli Dongshan 10 k V wind and solar hybrid power station,and carries out design research on the project.It mainly designs and completes the construction of Manzhouli Dongshan wind power generation grid-connected project;low-voltage electrical design of grid-connected system;photovoltaic and wind power generation design;related design of the grid management system.The article first discussed the feature of two kinds of energy,and analyzes structure and equipment configuration of wind-solar complementary grid-connected power generation,including wind turbines,photovoltaic arrays,inverters and grid-connected controllers,and field layouts.The structure,function and performance of the integrated data acquisition system and monitoring system are given,and the operating principle and working characteristics of each part are given.Secondly,combined with the actual development process of grid-connected system,the whole system of wind-solar complementary gridpower generation was studied,and the economic and social benefits of the actual engineering application of the system were analyzed.After the actual operation,the reliability of the system is verified,and the economical and effective operation of the grid-connected system is guaranteed.In order to explore the access and construction mode of distributed generation,it provides theoretical,technical and practical basis for the construction ofintelligent distribution network.
