At 16:190 on December 23, the world's first turbine generator set with high-level arrangement made by "Harbin electric power" was put into operation. The world's first turbine generator set project with high-level arrangement provided by Harbin Electric Power Group - Shenhua Shaanxi Guohua Jinjie Power Plant Phase III expansion drive in the field of new materials. Unit 5 of Taishan quality certification construction project successfully passed the 168 hour full load test run, during which the unit operated smoothly, At 16:16 on December 23, all parameters reached or exceeded the design value. Unit 5 of Shenhua Shaanxi Guohua Jinjie Power Plant Phase III expansion project, the world's first steam turbine generator unit with high-level arrangement provided by Harbin Electric Power Group, successfully passed the 168 hour full load test run. During this period, the unit operated smoothly, and all parameters reached or exceeded the design value, marking the formal putting into commercial operation of the unit. During the implementation of the project, the project team of Harbin Electric Power Group has been stationed on the site for a long time, actively communicating with the owner and cooperating with the on-site analysis and treatment, which provides a prerequisite for the smooth start-up of the unit

the project adopts the world's first high-level arrangement scheme of steam turbine. The steam turbine generator unit is arranged on the 65m operation floor, and the overall height of the main power house is about 85m. Compared with the conventional air cooling system, the exhaust steam of the steam turbine is directly discharged from the low-pressure cylinder to the air cooling island, and the conventional low-pressure cylinder exhaust device is canceled, which can significantly reduce the resistance of the air cooling system; After the high-level arrangement, the length of the four main pipelines at the furnace side is shortened, which reduces the pipeline resistance and coal consumption, and eliminates the hidden danger of vibration due to the shortening of the condensate return riser. It not only reduces the investment cost, but also reduces the operation cost, which lays a foundation for overcoming the technical problems of the 700 ℃ new generation ultra supercritical unit, which is required by the European reimbursement vehicle law to improve the vehicle recycling capacity. Among them, the steam turbine is a single reheat, three cylinder, two exhaust, direct air condensing steam turbine designed and manufactured by the turbine company of Harbin Electric Power Group. The generator part adopts the generator with full air cooling structure and full sealing technology designed and manufactured by Harbin Electric Machinery Co., Ltd., which effectively solves the problems of leaving holes for anchoring anchor screws, installation circuits and easy access of sensor pipes to the ventilation cooling system when pouring concrete for dirt and humid gas

it is understood that the project is located in Shenmu county, Yulin City, Shaanxi Province. It is a key construction project of the national air pollution control plan, a key planning and construction project of Shaanxi Province during the 13th five year plan, and an important power start-up point of the north channel of the national "West to East power transmission". At present, the third phase expansion project under construction is two 660MW ultra supercritical air-cooled coal-fired generating units. After the completion of the project, the coal in Northern Shaanxi will be more efficiently converted into clean electricity, which will be directly transmitted to Beijing Tianjin Hebei region, which is of great significance to the prevention and control of air pollution in Beijing Tianjin Hebei region and the protection of power supply in the core areas of the motherland
