摘要

针对独立发电机或为当地负载供电的多台发电机的传统控制系统不具成本效益。这是因为，在微型或小型水电站额定功率变化较大的情况下，控制系统的成本几乎保持不变。因此，设想使用同步发电机和感应发电机的组合可以降低机电设备的成本。同步发电机可满足负载的无功需求。建议使用频率敏感型负载控制器在系统中提供可变负载，以便使两台发电机看到的负载因用户负载的变化而保持恒定。这将确保系统电压和频率的恒定运行。

Voltage and frequency control of parallel operated synchronous and induction generators in micro hydro scheme

The conventional control system for a standalone generator or more than one generator feeding the local load is not cost effective. This is because of the control system cost remains almost the same for the wide variations in the mini or micro hydro plant power rating. It is therefore envisaged that while using the combination of synchronous and induction generators can cut down the cost of electro-mechanical equipment. The synchronous generator may provide reactive requirements of the load. The frequency sensitive load controllers is proposed to provide a variable load in the system in order to make the load seen by two generators, due variation in the consumer load remains constant. This shall ensure the constant voltage and frequency operation of the system.
