联合循环机组部分负荷性能试验方法研究

Study of Partial Load Performance Test Method for Combined Cycle Unit

联合循环机组部分负荷性能特性及性能试验时的运行方式与100%负荷时完全不同,部分负荷性能如何验收成为难题。采用在IPSEpro平台上自主开发的联合循环热力计算工具展开联合循环机组部分负荷性能特性分析,并基于ASME PTC46标准,参考联合循环100%负荷性能试验方法,提出了适用于联合循环单轴和分轴机组的部分负荷性能修正方法和试验方法。研究成果可为联合循环机组部分负荷性能考核试验提供理论指导。

There is great difference between partial load and 100%load from aspects of performance characteristics and the operation mode during the performance test in combined cycle unit,therefore,the acceptance standard has become a problem.The partial load performance characteristics of combined cycle were analyzed adopting the heat calculation tools for combined cycle developed on the IPSEpro platform.Based on the standard ASME PTC46,the correction method and test procedure under partial load for combined cycle unit with single shaft and multi shaft were proposed according to the test procedure under 100%load.The research result can provide theoretical guidance for the partial load performance test of combined cycle unit.
