Problems solved by technology

[0002] In the current harmonic reactive power compensation generation system, all harmonic reactive power compensation modules are put into use. There is no communication between the modules, and they can only complete their own compensation tasks. There is no systematic overall control scheme, which can still be guaranteed. Harmonic reactive power compensation in the power grid works, but once a harmonic reactive power compensation module in the harmonic reactive power compensation system fails, other modules cannot automatically change their assigned tasks, and the harmonic reactive power loss in the power grid will be unavoidable. to an effective reduction, making the compensation effect worse
[0003] On the contrary, if the reactive power capacity in the system is small, all the harmonic reactive power compensation modules will work as usual, which cannot effectively improve the service life of the modules and also increase the active power loss of the power grid, so the whole system urgently needs a system customized control scheme
