Through-flow parameter optimization effect improvement and peak regulation system for main compound turbine of front machine

The invention relates to a through-flow parameter optimization effect improvement and peak regulation system for a main compound steam turbine of a front machine. A front two-cylinder steam turbine, an electric generator of the front two-cylinder steam turbine, a heater 0, pipelines and accessories of the pipelines are additionally arranged and form the system together with a main steam turbine. A method that the front steam turbine is used for increasing circulation initial parameters is fully used, pressure level group parameters of the main steam turbine are optimized, the peak regulation performance of a thermal power generating unit is improved, and the circulation thermal efficiency of a thermal power plant and the relative inner efficiency of the steam turbines are improved. For the active-duty unit, the system can increase capacity, improve efficiency improvement and reduce the station service power consumption rate, so that the purpose that the ultra-high pressure and ultra-high temperature heat supply steam extraction function is provided by a condensing steam turbine is achieved. In the aspect of optimized design of a thermodynamic system of the new-built thermal power generating unit, a technological path that thermalized steam flow can be fully used and the unit is suitable for wide-load peak regulation operation is provided. By the application of the through-flow parameter optimization effect improvement and peak regulation system, remarkable energy-saving emission reducing economic benefits and social benefits can be generated.
