摘　　要：探讨了引进型300MW机组带旁路中压缸启动方式的可行性,并与不带旁路高压缸启动方式比较。分析了在DEH控制下的启动方式选择以及旁路系统、通风阀在中压缸启动方式中的作用和控制条件,介绍了在DEH控制下中压缸启动过程,提出了针对中压缸启动方式的几点保护。Discusses the feasibility of starting ways of intermediate pressure cylinder with bypass system for imported 300MW turbine, and compare with high pressure cylinder without bypass .Analyzes the option of starting ways and bypass system under the control of DEH, the role and controlling conditions ofventilated valve in intermediate pressure cylinder starting ways. Introduces the starting process, put forward several protective measures aiming at the intermediate pressure cylinder starting ways.

关 键 词：中压缸启动 旁路系统 通风阀 DEH-Ⅲ保护
