【摘要】 车载行车取力发电系统用途广泛。采用异步发电机作为行车取力发电机,使用V/F控制发电的策略简单可靠。异步发电控制策略一般采用给固定滑差开环缓起建压。但异步发电系统的快速建压与较小的电压过冲两个指标难以同时满足。针对这个问题,提出一种根据输出电压情况调整给定滑差的变滑差缓起建压的控制方法。通过仿真与实际台架拖动发电机试验验证了所提方法的有效性和工程实用性。更多还原

【Abstract】 Vehicle-mounted power generation system is widely used. It is simple and reliable to use asynchronous motor as driving force generator which is controlled by the V/F control strategy. Normally, fixed slip for open-loop is given to control asynchronous generator in the voltage buildup process. However, it is difficult to meet both the fast voltage buildup and the small voltage overshoot of asynchronous generation system. To solve this problem, a variable slip voltage buildup control method is proposed, in which the given slip is adjusted according to the output voltage. The effectiveness and engineering practicability of the proposed method are verified by and practical bench driven generator experiments.更多还原
