Research on Electric Energy Measurement Method of Energy Measurement Instruments with Unbalanced Load
The installed capacity of new energy connected to the power grid is increasing,and its randomness,vola-tility,intermittency and other characteristics reduce the anti-interference of the power system.And a large number of nonlinear loads,such as the capacity of power electronic devices connected to the grid is increasing,such loads can lead to grid voltage plummeting,sudden rise and other problems,but also lead to the randomness and uncertainty of the grid increase,further reduce the anti-interference of the power system.The nonlinear and asymmetrical load is connected to the power grid,and the accuracy of electric energy measurement will be reduced.In this paper,a cal-culation method of forward push-back generation power flow is proposed to measure the electric energy of three-phase unbalanced power network,and a 10-node power network is taken as the simulation object.The simulation re-sults show that:when the load access node is farther away,the power change at the balance node is greater.
