The turbogenerator unit provided by the utility model has the characteristics of reduced auxiliary power ratio of a power plant, saved equipment investment, simple system and the like, can be applied in engineering, and provides an excellent solution for reducing auxiliary power ratio of a fuel electric plant and increasing net output electrical quantity.
Description
Technical field:
The utility model relates to thermal power plant engineering and electric field, especially relates to a kind of house generator equipment of Driven by Coaxial.
Background technique:
Station service power consumption rate is one of power plant's main economic and technical indices, and China's power industry is commonly considered as the percentage that necessary own demand in the power station power production process accounts for generated energy.The station-service electric weight comprises the electric energy that motor in the power production process, illumination, heating and ventilation and other control, protective gear etc. are consumed.
In recent years, along with the improvement of electric power factory equipment performance, the improvement of design level, managerial skills and the raising of automatic control level, the station service power consumption rate of China power plant also decreases.Different units, different capabilities station service power consumption rate generally account for the 4%-8% of nominal output, and by present dispatching of power netwoks situation, clean electricity volume will be deducted station service, and the unit of same capability, station service are high more, and clean electricity volume is few more.In order to reduce station service power consumption rate, present many power plant have adopted the steam-operating supplementary equipment in a large number, have the problem of equipment investment height and system complex.
The model utility content:
The purpose of the utility model is to overcome the shortcoming of above-mentioned existing technology, and a kind of Turbo-generator Set of Driven by Coaxial house generator is provided, to solve thermal power plant steam-operating auxiliary equipment system complicacy and equipment investment problem of higher.
The purpose of the utility model solves through following technological scheme:
The Turbo-generator Set of Driven by Coaxial house generator comprises steam turbine, main generator and house generator, and said main generator links to each other with steam turbine, and main generator is connected to main transformer through enclosed busbar.
Said house generator adopts 6kV/10kV directly to supply power or is connected to the station-service power supply system through bus.
Said house generator, steam turbine and main generator group Driven by Coaxial, house generator are arranged in the steamer pusher side or are arranged in the main generator side.
Said steam turbine and main generator are installed in steam turbine basis running layer platform, and main generator is connected with steam turbine afterbody output shaft through coupling, and house generator is arranged in motor side, links to each other through coupling and main generator are coaxial.
Said steam turbine and main generator are installed in steam turbine basis running layer platform, and main generator is connected with steam turbine afterbody output shaft through coupling, and house generator is arranged in the steam turbine side, and is coaxial with steam turbine, links to each other through coupling.
The characteristics of the utility model and existing technology comparison are:
(1) to present dispatching of power netwoks situation; Can reduce the thermal power plant station service power consumption rate effectively; Save the investment of steam-operating supplementary equipment, can reduce 3%-7% for 600MW and 1000MW unit station service power consumption rate, power plant is annual because many sales of electricity can increase by 3,000 ten thousand yuan-6,000 ten thousand yuan income;
(2) system is simple, can cancel the station-service high-tension transformer, reduces the electrical system loss;
(3) synchronous with main generator, not influenced by extra factor.
