摘要
交直交变频调速系统是矿井提升传动的主流发展方向,其中三电平拓扑方案结构简单,可靠性高,四象限运行控制易于实现。根据煤矿提升系统中对于传动的实际需求,提出了交直交变频系统的冗余方案,很好地满足了矿井提升的高可靠性要求。
The A- D- A variable- frequency speed control system is the mainstream development direction of mine hoisting and driving. Among them,the three- level topological solution has simple structure,less components,high reliability and easy control of four- quadrant operation. In this paper,according to the demand for driving of mine transmission,a redundant scheme for A- D- A variable- frequency speed control system is put forward,by which high reliability demand for mine hoisting can be well met.
