变频技术在烟风系统节能改造中的研究与应用
- 引风机是火力发电厂重要的辅助设备,传统的引风机系统采用通过调节挡板开度的方式调节风量,这种调节方式耗电量较大,以高压变频器为核心的变频调速系统以其效率高、应用范围广和节能效果显著的特点在节能改造方面得到了广泛的应用。(With the deepening of the power system, power generation companies competition is increasingly fierce, and effectively reduce the co
异步电机直接转矩控制变频调速系统的设计_胡瑶
- 本文建立了一个基于直接转矩控制的异步电机变频调速系统。系统采用了两个滞环控制器,分别比较定子给定磁链与实际磁链、给定转矩与实际转矩的差值,然后根据这两个差值查询逆变器电压矢量开关表得到施加在异步电动机定子绕组上的电压矢量,然后通过脉冲宽度调制(Pulse Width Modulation,PWM)逆变器控制异步电动机。(An asynchronous motor variable frequency speed regulation system based on direct torque c
