The present invention makes it possible to start the engine when switching from the electric driving (EV) mode to the hybrid (HEV) mode without feeling of torque loss and with low impact. At t1 when the EV→HEV mode switching request increases with the acceleration, the control is started using the mode 2301b, and the transmission torque capacity tTc1 of the first clutch for HEV is increased for driving force control. Before the second clutch for EV&HEV starts to slip, The PTO shaft of the engine is started to rotate by the drag of the first clutch. In the mode 2301b, the second clutch transmission torque capacity tTc2 is maintained at the maximum driving force evTmax in the EV mode. Switch to mode 2303 at t2 when the second clutch starts to slip, and determine tTc2 so that the second clutch slips and start the engine caused by the drag of the first clutch, and tTc1 is determined to maintain the increase in driving force and the stability of the second clutch slide.

The invention discloses a method for starting an ultra-weak receiving-end high-voltage direct-current (HVDC) power transmission system by using a static synchronous compensator (STATCOM), belonging to the technical field of HVDC power transmission. The system is characterized in that a STATCOM and HVDC are connected to a same bus of an alternating-current system in parallel, and a STATCOM subsystem is connected with the same bus of an HVDC subsystem receiving-end alternating-current system through a current conversion reactor (X1).
