Technical field
The present invention relates to a kind of distributed gas turbine power generation system.
Background technique
Along with the increase day by day to power requirement of the enlarging day by day of electric power system scale, user, distributed power generation will occupy more and more important position as a kind of competitive generation mode in modern power systems.Distributed power generation with its less investment, generation mode flexibly, with characteristics such as environmental compatible and big electrical network cooperation day by day, bring huge variation to modern power systems operation and control.It both can satisfy electric power system and user's particular requirement, as peak clipping; Traditional unrivaled reliability of electric power system and and Economy can be provided again.The distributed power supply mode realizes electricity, hot and cold joint supply mode with characteristics such as its small scale, flexibility are strong, for the comprehensive cascade utilization of the energy provide may, have higher efficiency of energy utilization.Because distributing electricity generating device workflow is simple, the system that participates in operation is few, thereby start and stop are quick, have good peaking performance when being used with electrical network, and is convenient to realize full-automatic.
Current distributed gas turbine power generation system generally can be regarded as the miniaturization of large-scale gas turbine power generation system.The same with a lot of large-scale gas turbine power generation systems, distributed gas turbine power generation system is still very strong to the fuel dependence, requires the local operation that has sufficient fuel source to guarantee power generation system.Yet the resourceful area of China's combustion gas is very limited, is building distributed gas turbine power generation system away from combustion gas resource region, the one, set up special fuel gas pipeline, and cause and generate electricity into branch and significantly rise; The 2nd, be difficult to ensure the without interruption of combustion gas.In addition, distributed gas turbine power generation system belongs to the power generation system of open type, and the generator set operation is subjected to Effect of Environmental consumingly, and the variation of factors such as ambient temperature all can seriously influence the performance of distributed gas turbine power generation system.For distributed gas turbine power generation system, supply of fuel and unit operation all need the special messenger to be responsible for supervision constantly, and maintenance cost is higher.
Summary of the invention
The objective of the invention is for solve the existing distributed gas turbine generating system strong to combustion gas place of production dependence, be subjected to the problem that such environmental effects is big and operation and maintenance cost is high, a kind of solar distributed closed gas turbine power generation system has been proposed.
