摘要
介绍利用美国A－B公司1557型中压变频器对某电厂送风机控制进行改造的实例，分析变频调速原理及特点和在送风机控制中实际运行效果。实践证明，该中压变频器对于6000V、800kW的高压大功率电动机可实现稳定调整，并且运行可靠、节能效果显著，可在电厂中广泛推广应用。
The paper introduces the retrofit example of forced draft fan control in one thermal power plan by using A-B Co.1557 medium voltage frequency converier,analyzes the principles and features of frequency control of motor speed draft fan control. The practice proves that, this medium voltage frequency converter can realize steady regulation for 6000V.800kW high voltage large size motors,operate reliably, with remarkable energy-saving result gained, and may be popularized and applied in fossil power plants.
