高压变频器在300MW发电厂引风机上的应用

随着电力生产成本不断增长,发电企业采取种种措施节能降耗,高压变频器以其可观的节能效果而被广泛推广使用。从改造方案、设备选型、变频器的特点、运行效果等方面,介绍了美国罗宾康公司生产的完美无谐波变频器在300MW发电厂锅炉引风机系统上的应用,并对实际的节能效果进行统计分析。实践证明,辅机设备采用变频调速后使发电厂用电率明显下降,效益显著。

Application of 300 MW High Voltage Converter in IDF of Power Plant

With the constant increasing of the power production cost,the electricity power enterprise takes lots of measures to save energy and reduce the cost.The high-voltage converter is popularized extensively with its considerable energy-conserving result.Based on transforming respects such as the scheme rebuild,equip- ment selecting type,characteristics of converter,operation result,etc.,introduced the perfect harmony medi- um voltage drives which is made in united states robincon,and the application in boiler IDF of 300 MW power plant,and carried on statistical analysis to the real ernergy-conserving result.The practice proves that the e- quipment of the auxiliary machine which adopt frequency conversion to adjust the speed,makes power consu- ming rate of power plant obviously drop and factory's benefit prominently increase.
