Embodiment Construction
[0023] The harmonic and reactive power comprehensive compensation device combined with the active power filter and TSC of the present invention and its working principle will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] like figure 1 , 2 As shown, it includes a detection control unit, a thyristor switching capacitor module and an active power filter respectively connected to the power grid. The switching device connected to the trigger pulse output end of the circuit. Three groups of high-order LC filter branches are adopted, and each branch is connected to the power grid at the side close to the load through the thyristor group of the thyristor switching capacitor module.
[0025] The far right is the non-linear load, and the thyristor switched capacitor module (TSC) is connected in parallel with the power grid near the load side. It can be determined according to filtering and reactive performance requirement...
