The invention provides an electric energy quality demonstrating platform and an operating method thereof. The electric energy quality demonstrating platform which comprises a reactive load that is connected with a power grid through a circuit breaker and a reactive compensation module that is connected with the power grid through a circuit breaker, wherein the output end of the reactive compensation module is connected with a display module; a harmonic wave treatment effect demonstrating platform which comprises a harmonic wave source load that is connected with the power grid through a circuit breaker and a harmonic wave treatment module that is connected with the power grid through the circuit breaker, wherein the output end of the harmonic wave treatment module is connected with the display module; and a three-phase unbalance compensating effect demonstrating platform which comprises a three-phase unbalance load that is connected with the power grid through a circuit breaker and a three-phase unbalance treatment module that is connected with the power grid through the circuit breaker, wherein the output end of the three-phase unbalance treatment module is connected with the display module. The electric energy quality demonstrating platform more visually demonstrate an effect before and behind reactive compensation and three-phase unbalance compensation caused by low power factor in harmonic current treatment.
Description
technical field [0001] The invention relates to the field of power quality detection and demonstration, in particular to a power quality demonstration platform and an operation method thereof. Background technique [0002] With the development of power electronics technology, various rectifiers and other power electronic devices are widely used in industry, transportation and household appliances. In the distribution network, due to the variability of power loads, power harmonics, reactive power and Various problems of power quality such as three-phase unbalance often coexist, and they will bring various hazards to the power grid and power users. With the development of high-tech industries, power users have higher and higher requirements for power quality, and more advanced equipment has higher requirements for power quality, which poses a great challenge to the power supply side. But at the same time, the power quality problem in the low-voltage distribution network is ma...
