The invention provides an electrical simulation method for an alternating current energy consuming device of flexible high voltage direct current. The method comprises the following steps that a mainwiring diagram of the alternating current energy consuming device and parameters of power equipment are obtained; a component level model is established based on the power equipment; an alternating current energy consuming device system simulation circuit model is established based on the main wiring diagram; voltage and/or current detecting units are arranged at one or more nodes in the power equipment; operating states and fault conditions of the alternating current energy consuming device are changed, and the voltage and/or current detecting units obtain voltage and current data.
