Wind-driven generating set and offshore platform grid non-stop grid connection test system and method

The invention discloses a wind-driven generating set and offshore platform grid non-stop grid connection test system and a wind-driven generating set and offshore platform grid non-stop grid connection test method. The method adopts the following test steps: 1, electrifying devices of the test system; 2, starting the wind-driven generating set, running with no-load, confirming whether raising speed and vibration are normal; 3, carrying out a wind-driven generating set start grid operation loading process test and a normal halt process test; 4, carrying out an urgent halt test of the wind-driven generating set with loads; 5, carrying out a grid load sudden-loading and sudden-unloading test; and 6, carrying out a grid generating complementary running test of the wind-driven generating set and a heating power set. In the system and the method, the grid connection test is performed on the wind-driven generating set and a simulated offshore platform grid on land first and then the wind-driven generating set is integrally transported to the sea for installing after regulating, so accidents of power failure and production stop in an offshore grid connection process are avoided.
