摘要 | A wind generator equipped with hydraulic energy storage (WG-HES) uses hydraulic transmission systems instead of gearbox transmissions, thus eliminating high-power converters and reducing the tower-top cabin weight. When there is no wind or the wind speed is extremely low, the pressured oil released by accumulators is used to drive a motor to operate at a constant speed, thereby generating constant-frequency power. However, few studies have examined the constant speed control characteristics for generating electricity using only an accumulator group. In this study, a combined constant speed (CCS) proportional-integral-derivative (PID) control method based on "variable displacement and throttling" is proposed, which includes two closed loops and one regulating loop. First, a simulation model of the CCS PID control method for a variable motor was established in the Simcenter Amesim program. The influence of different PID parameters on the anti-interference ability of the constant speed control of the motor was analyzed under a given load step. Then, we obtained the range of control parameter values and a set of optimal values. Second, the effectiveness of the CCS control method and the accuracy of the simulation results were verified on a 600-kW WG-HES system prototype. The results verified that the CCS control method has good anti-interference ability and can meet the requirements of constant speed control for a variable motor under the best PID parameters. These results can provide a basis for developing control strategies for WG-HESs when there is no wind or at low wind speeds. |
