Application Of Inverter In The Thermal Power Plant Modification Research

Electricity as today’s Chinese society is the most important is the pillar position ofsecondary energy, the demand for geometric rate increased year by year. Tianjin, asone of the four municipalities directly under the central government, the electricitydemand is also rising year by year. The power supply of the main six large fire powerstation from the city, as one of six main modern plant of tianjin, tianjin guodian tothermal power co., LTD., tianjin annual capacity of3.3billion KWH, it is veryimportant for the economic and stable operation of the unit, the direct relationshipbetween social economy and the people the livelihood of the people. Thermal powerplant unit economic, stable and safe operation of the main depends on the energyconsumption and reliability of important auxiliary equipment. The development of theelectronic frequency conversion technology, to solve the important fire power stationauxiliary equipment energy consumption and improve reliability provides acost-effective means of, the effect is remarkable. At present, based on the electronicfrequency conversion technology research and development of medium and highvoltage general converter has been widely used in thermal power plant of the actualproduction.In this paper, based on the research of electronic frequency conversion technology andheat power production practice, put forward the application of frequency converter forimportant auxiliary equipment of thermal power plant energy saving and reliability ofthe transformation method, and through the experiment data and engineering practiceof the application effect of proposed method is verified. This paper main job:1. From the use of energy efficiency, operating costs and social benefits, etc., thispaper expounds the important auxiliary equipment fire power station unit energyconsumption and improve the reliability of important meaning;2. The proposed inverter in the thermal power plant unit important auxiliaryequipment modification methods of saving energy and reducing consumption, andthrough the tianjin guodian to thermal power co., LTD., induced draft fan speedcontrol system of inverter is verified.3. The proposed inverter bypass system reform important auxiliary equipments inthermal power plant unit reliability enhance transformation method, and through the tianjin guodian to thermal power co., LTD., a frequency conversion fan bypassverified.
