Along with the widespread app lication of large-volume&high-parameter hydrogen-cooling Generator in recent years,the sealing oil system of Generator is getting more and more important.So the article as following states comprehensively the analysis and handling tactics of often-happened fault and problems on the sealing oil system of large-scale Generator used currently.

Combined with current power generation and operation, the article summarizes the viewpoint of frequency conversion control of condensate pump and its application and practice.

During the adjustment and test running,large-scale steam turbine units have various problems inevitably.Through the adjustment and test running work,thoroughly analyse and ultimately solve the problems impacting of the security,stability and economy of the units. Not only for the transfer and pre-production of units lay a solid foundation,so the power generation companies can make considerable economic benefits,also discover relevant companies own improve space in installation,production or design of products.

The conventional load-rejection test method is a necessary condition for newly constructed units to put them into operation for connecting them onto the power grid,a systematic approach to the necessary conditions before load-rejection test,the method of load-rejection test,and its anticipated objectives,as well as the problems frequently encountered in the test,and their solving methods,has been carried out.

As the importance and complexity of load-rejection test of large-scale steam-turbine&generator unit,the article states comprehensively about the current test method,key point and counter-measures,met problems,analyzing and processing,etc.for reference.

During the whole process of integrated commissioning stage of Zhengzhou Gas Power Plant which installed with 2×390 MW(Siemens GUD1S.94.3A) Gas-Steam Combined Cycle Units,there are lots of commissioning works,such as GT ignition & start-up,synchronizing,blowing of HRSG,safety valve setting,GT high load adjust and test,ST startup and running with load,combined cycle full load test and reliability test,etc.have been executed successively.The abnormal shutdown events occurred in commissioning are analyzed in the article to avoid any duplication of similar in the future and lay the good foundation for units commissioning hereafter.
