Variable Speed Fan(VSF) Drive System with Airflow Pressure Monitoring 风扇变速驱动及气流压力监测系统
An Optimal Control Model of Variable Speed Operation for Fan in Power Plant Based on Neural Network 基于神经网络的电厂通风机变速调节优化控制建模
The test shows that the vector control speed system has low inverter power, high power factor, perfect dynamic performance, wide speed range. It suits the variable speed system of fan machine and pump and has good prospect on industry application. 试验证明调速系统具有变频器功率小、功率因数高、动态性能好、调速范围广等优点,适用于风机、泵类负载的调速,有良好的工业应用前景。
Points out that the methods of determination of working state of variable speed of pump / fan are different whether the back pressure in a piping system exists or not. 指出了管路系统在有无背压情况下泵/风机变速工况确定方法上的不同。
