The invention relates to an
electric energy quality
harmonic disturbance source platform. In the disturbance source platform, an input
circuit breaker cabinet, a disturbance source input switch cabinet, an output filter and switch cabinet and an output test cabinet are all connected to a 10kV
bus; the disturbance source input switch cabinet, an input
transformer and unit cabinet, the output filter and switch cabinet, a switch and
output transformer cabinet and the output test cabinet are sequentially connected; the output test cabinet, the input
transformer and unit cabinet are connected with the
input control cabinet; the
electric energy quality
harmonic disturbance source outputs 0-50 times or stacking folds of standard
harmonic voltage current source with adjustable amplitude and phase under the conditions of 10kV and 0.38kV fundamental voltages, and the maximal
total harmonic distortion THDu is less than 20%. The platform can be used as a standard
electric energy quality harmonic output source and a
power grid equipment assessment platform for testing operation stability of a
power grid and performance of
power grid equipment under the harmonic output condition; electric
energy quality problems about sag, fluctuation and three-
phase imbalance of the power grid are simulated, and a platform is built for test, analysis and assessment of electric
energy quality improvement.
