Abstract
|
With the economic development of our country rapidly, society activities propose such more urged demand on production of electric power. At the same time, complex electric system calls for more production security. Many Power cuts especially caused by natural disasters intimidate function of electric-net severely. Ice calamity occurred at the beginning of 2008 resulted paralysis of backbone of 500Kv entirely and it will be a gospel for everybody if some power generation plant can survive in that accident. What’s the most efficient method to elevate security of power generation? That’s FCB.FCB(Fast cut back) is such function that the unit of power cease plant power supply immediately when e-net fail down which will induce control system to maintain safe circulation of lower load or to insure pause himself safely. So the unit will resume power supply to e-net when troubles are managed. Therefore, the research on how to realize FCB function in supercritical 600MW units made inland is very important.The paper investigates the feasibility of FCB on the unit firstly, and then analyzes the characteristics of unit equipments and technical difficulties. We put forward best reconstruct project after many comparisons. Successful experiment are actualized on unit 3. Influences on the unit security and life-span of turbine once in run-mode of FCB are summarized in detail. After such interesting duration of research we can conclude that such special unit of LANXI power generation plant can implement FCB with some technical optimizations which will be the best references to the similar unit.
