电子负荷调节器是用于孤立运行的微型水力发电机组转速控制的一种新型稳速装置。它不同于机械调速器的调节方式,不需要调节进水量,在外负载变化或水头流量改变等扰动使机组力矩失去平衡时,靠调节平衡负载来保持机组转速稳定。四川省机械研究设计院研制的DFT-1-1型单相1kW和DFT-3-26型三相26kW电子负荷调节器近三年来的实际运行表明,该类装置与机械调速器相比有如下特点: 1.由于调节器采用了电子控制技术,能够快
Electronic load regulators are a new type of speed-stable device for speed control of a mini hydro-generator set in isolated operation. It is different from the mechanical governor adjustment method, do not need to adjust the amount of water, in the external load changes or changes in the head flow disturbance to the unit torque out of balance, by adjusting the balance load to keep the unit speed stability. DFT-1-1-type single-phase 1kW and DFT-3-26-type three-phase 26kW electronic load regulator developed by Sichuan Machinery Research and Design Institute in recent three years show that this type of device has the following advantages compared with mechanical governor: The following features: 1. As the regulator uses electronic control technology, fast
