At present buiiding small hydropower plants is an important electric power development way in china.In our country,we use computer monitoring system in big or medium hydropower plants at large.But because small hydropower plants have some characteristics,for example local signals are simple,economic condition is limit and so,the computer monitoring system of hydropower plant has its particularity.Taking heihe hydropower plant as object,referring to inspection and control mode and computer control at process production of big or medium hydropower plant,as well as sufficiently considering the course charicteristic of small hydropower plants,this thesis studies basic demands,configuration and realizable methods for computer monitoring etc system of small hydropower plant.This paper demonstrates the computer monitoring system and chooses configuration of heihe hydropower plant, and computer network, LCU and innovates. Network adopts rapid Ethernet with the speed of 100Mbps, LCU uses reliable QUANTUM PLC and MB+ field network which are widely applied. Each parameters achieve expected requirment. We analyze some questions occurred in the field,such aselectromagnetisom etc,and put forward solutions.Now,we have gotten a good result. |
