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.

Description

technical field [0001] The present invention relates to a wind power generating set, in particular to a test system for wind power generating set and offshore platform power grid non-stop production grid connection test system for preventing the wind power generating set from affecting the stability of an isolated small power grid during the grid connection process and causing an offshore production platform power failure and shutdown accident. method. It belongs to the field of mechanical power system. Background technique [0002] In offshore oil development projects, the power required by traditional offshore production platforms is generally generated by fuel or gas generator sets, and the power energy is transmitted to each production platform through submarine cables to supply power for offshore production platforms. The existing offshore production platform power grid is usually connected to the grid between fuel oil or gas generating units, and the power of each uni...
