The invention discloses a test method for IGBT overcurrent shutoff of a voltage source converter valve of flexible direct current power transmission engineering. A test loop adopted in the test method consists of an energy compensation valve V3, a test power supply S, a test capacitor C, a test product valve V1, a test product valve V2, a test electric reactor L1, a current limiting reactor L2/L3, a direct current short circuit branch, an isolation switch K01 and an isolation switch K02. The test method comprises the following steps: enabling the test product valves to be in stable continuous running states, controlling the direct current short circuit branch and an accompanying test valve to trigger a direct current short circuit event at a preset moment, so that the test product valves generate direct current short circuit between the positive and negative electrodes through short circuit points, wherein after the IGBT protection of the test product valves is shut off, the reactors L1 and L4 are continued through a current continuation diode until the current is attenuated to zero. The test method can meet the requirement on the IGBT overcurrent shutoff test of the voltage source converter valve, namely in a specific short circuit fault or mis-triggering, due to the design of the voltage source converter valve, particularly the design of an IGBT and a relevant circuit therefore, current and voltage stress produced by the shutoff can be borne.
