National scenery storage lose demonstration plants complete electrical failure process for the first time back at home and abroad

As the landscape of new energy power in recent years the rapid increase of the permeability in the grid rising, even the state of wind power station wind even states for power system stability proposed the new challenge. Recently, polysilicon its latest price movements in the north electric power company in the country scenery storage demonstration losing power station completed for the first time at home and abroad in the regional power grid failure process actually occurs, and complete the function of virtual synchronous machine under the real power grid failure test. At the same time, in the process of test, the new power plant project has carried out a virtual synchronous machine PC, multimachine parallel cases such as comprehensive test. According to different FM and inertia parameters and under different power grid frequency and voltage, and so on and so forth, to complete the virtual real action characteristics of synchronous machine in the power grid failure tests, confirmed the before stage technical achievement, for subsequent research provides a new direction. Given to promote the new energy use, since this year, hebei north power regulation, science and technology department, polysilicon prices latest group scenery storage, ji nortel, Xu Ji, solar panels principle research institute south units such as joint research, cutting silicon mud jointly compile testing plan, carry out various kinds of simulation analysis and test equipment, during the demonstration plant annual outage maintenance carried out joint test. New power plant project, in the process to carry on the power grid voltage frequency variation, low frequency disturbance, such as solar panels principle of harmonic injection experiment, and according to & other 919' East China power grid failure process, the British & other; 89' Grid accidents at home and abroad for the first time in the power grid failure process, new energy equipment for our country scenery of interconnection function test provides the powerful technical support. Through the experiment, on the one hand, to verify the effectiveness of the virtual synchronous machine technology and the necessity, on the other hand, also shows the scenery storage demonstration project is the first at home and abroad with grid on a large scale events reappear test platform. Hebei north power follow-up will through the in-depth study of virtual synchronous machine, the scenery storage technology experiment platform construction, for the smooth development of new energy future power grid enterprise in our country to lay a solid foundation. Engineering training for the test, project design training based on national scenery storage demonstration plants unique to run and test equipment, under the regional power grid, the building contains many turbines, photovoltaic (pv), energy storage and the variable load experiment environment, it can change a variety of grid parameters to meet different test.
