Research On Tests Equipment & Test Methods Of Power Filter Product

A large number of power electronic is put into power grid, harmonic component proportion of the grid become more and more big, the power factor become more and more low, and cause the voltage fluctuation and flicker, three-phase imbalance and a series of serious power quality problems, so harmonic control is very urgent. The best solution for harmonic control is installed using the active power filter in the factory substation of enterprise or large workshop power distribution room.Through the interpretation of these standards: JB/T 11067-2011、YD/T 2323-2011、JG/T 417-2013、DL/T 1216-2013, It is concluded that the experimental purposes and requirements. This paper analyzes the harmonic content of three-phase uncontrolled bridge rectifier circuit produces in the Standards. The circuit is only 6N±1 harmonic. Analysis of three-phase full controlled rectifier circuits, the harmonic contents is richer than control circuit, so this system adopts three-phase full controlled rectifier circuit in the harmonic loads.In order to complete the active filter product test to design a set of device. Through the interpretation of these product technical parameters and the parameters test method, this paper designs a set of active power filter product automatic detection system.The test circuit, test equipment, test procedure concentrated into the automatic detection system。Through the computer interface settings and button operation complete the test。The test circuit, test equipment, test procedure concentrated into the automatic detection system。The automatic detection system includes the test circuit, test equipment, test procedure. Through the interface of the computer settings and button operation complete test. At the same time, upload the test data and convenient Sorting Test Report.Finally use the system to complete the active filter test, and evaluate the test results.
