The Influence Of Wind Power Access To Tai’an Power Grid

In today’s society, development of science and technology change rapidly, The field of new energy power generation, power inscribed ratio increasing, new energy power generation and wind power generation for the human grasp belongs to the highest degree.the power in the field of wind power generation technology and wind power generation equipment level is accompanied by the development of science and technology is continuously improved, more and more new operation of wind power plant, wind power in the national electricity consumption constitute a proportion is more and more high. Wind power plant generating capacity and the level of mature up day by day. Now the following thermal power, hydropower, wind of this nature gives us new energy power generation has become the third large power in our country. But we also should see, wind power generation is also not be the pink of perfection, it also has some characteristics and limitations. It is because of wind power itself is stochastic uncertainty and with the wind strength and fluctuation of the typical characteristics, so with the continuous expansion of the scale of wind farm, wind power in the power system in the proportion of continuously improve, wind power grid connected this subject has attracted attention of the world power system, grid connected wind power is bring more and more challenges for the safe and stable and reliable operation of national power system.In summary, a series of studies carried out various effects of wind farms to the grid in the process of bringing the power system for, for us to improve the process of wind power grid reliability, stability and security, reducing wind power on affect the original traditional grid, reasonably safe use of wind energy has a good sense of nature and the reference value.The main contents of this paper is on the territory of Tai’an grid Dongping, pingyin two wind power plants in the actual operation of the power grid in the process of scheduling control problems that may occur once the first analyzes of two wind farms and network operation for the two wind farms and Tyan affect grid voltage, frequency, protection arising explore the relevance of pingyin, Datang wind farm wind power factor (cos(?)) and Tyan voltage fluctuations, and through the establishment of a typical example of simulation experiments to verify the level overcast, Datang bus operating voltage of wind farms and wind turbine output, the relationship between the power factor of the unit. Thus gives the voltage and reactive power control Datang, pingyin wind farm reactive power compensation configurations, some countermeasures and suggestions and relay configuration aspects.
