Summary:The invention discloses a testing system and a testing method of a 10kV/10MVA four quadrant high voltage frequency converter. The testing system comprises a tested frequency converter, two motors, three accompanying frequency converters, three transformers, five high voltage circuit breakers, and a connection cabinet. One end of the tested frequency converted is serially connected with the circuit breaker, and then is connected with a 10kV power grid, and the other end is connected with one motor. One end of each of the three accompanying frequency converters is serially connected with one transformer and one circuit breaker, and then is parallely connected with the 10kV power grid, and the other ends of the three accompanying frequency converters are parallely connected with the other motor. The two motors are coaxially connected together. The testing system is used for the full-power detection and testing of the three-phase 10kV frequency converters having capacities no more than 10MVA, and energy output te
