Study On The Access System Scheme For Changsha Waste Incineration Power Plant

With the rapid growth of Changsha's economy and its soaring population,the amount of waste inside the city has also rocketed.Waste produced in Changsha increased from 2126 tons/day in August,2006 to5292 tons/day in July,2013.It is projected,in ChangshaHeimifeng II Solid Waste Landfill Expansion Plan,that waste produced in 2020 will reach 6916 tons.There only exists one landfill in Changsha,with no incineration plant.Even though the waste can be buried,the disposal process has to be bio-safely.Even so,the total amount of the waste cannot be reduced.Therefore,there is a need for incineration power plant.Once the power plant is built,it can effectively improve the bio-environment in Changsha.The city will also become less dependent on the electricity supplied by power grid.With incineration power plant,city power grid will be more disaster-proof,and also more economical to run.This thesis aims at analyzing the plan for the connection system of equipment set of incineration power plant in Changsha.Four connection plans will be proposed based on the detailed study of Changsha city power grid.Using PSASP software,computation of the power flow,transient stability,active power loss when the project is completed will also be analyzed.In addition,the overall economic effect will also be taken into account.Therefore,this thesis will work out the optimal connection plan which requires less investment,boasts of long-term adaptability and higher stability in output.In the end,this thesis will analyze the secondary connection plan,and make a rather detailed investment assessment,expecting to provide reliable statistics for the establishment of incineration power plant in Changsha.
