A system includes a source side converter for being electrically coupled to a generator of a power source, a line side converter for being electrically coupled to a power network, a DC link coupled between the source side converter and the line side converter, and a controller for generating source side switching signals based on a current or torque of the generator and a virtual impedance signal for system damping or reactive power compensation when at least one detected signal of the system is not normal. A method for controlling the system is also included.

Power conversion system and controlling method thereof and wind turbine power generation system

An energy management system comprises a first electricity transformer with one or more first leg circuit(s), a second electricity transformer with one or more second leg circuit(s), and a control device. One or more first leg circuit(s) is (are) coupled to an energy-type supply, and one or more second leg circuit(s) is (are) coupled to a power-type supply. The control device will control the first and second electricity transformers operating under at least one of two conditions when a traction device is under driving mode.
