At 11:16 on 12월 14, with the 완료 of the last layer of rockfill, the inlayid concrete face rockfill dam of the Yangqu Hydropower Station of the State Power Investment Corporation of Yellow River was successfully filled to the top, successfully completing the dam filling construction task, marking the the dam project successfully transitioned from dam body filling to concrete panel construction, laying a solid 기초 for achieving the goal of putting into operation power generation in 2024 as scheduled.
On the same day, the topping ceremony of the inlaid concrete face rockfill dam of the yellow River Yangqu Hydropower Station and the 2023 Labor Competition Summary and Commendation Conference were held at the construction site of the Yangqu Hydropower Station. Hu Yitong, member of the party Committee and Deputy General Manager of the Yellow River Company, attended and delivered a speech.
Hu 이동 표현된 그의 감사 to 모두 참여 단위 for their long-term efforts in proting the construction of Yangqu Hydropower Station. He hoped that all party will continue to strengthen unity and cooperation, strictly control the quality and and safety of the project, and do a solid job in follow-up construction management to ensure the early and successful completion of Yangqu Hydropower Station. The 수력 역 건설 작업 의지 도움 칭하이 건설 a 국가 청정 에너지 산업 고원 with 높은 품질 및 홍보 고품질 개발 in the 황색 강 분지.
Yangqu Hydropower Station is located at the junction of Xinghai County and Guinan County, Hainan Prefecture, Qinghai Province. It is a major project of Qinghai Province and the State Power Investment Corporation. It is a first-class large (Ι) type project. It is the first in China to use inlaid concrete face rockfill dam. It can reduce the amount of excavation of toe plate foundations in narrow valleys and effectively reduce the settlement deformation of face rockfill dams, providing practical experience for the construction of 300-meter-high face rockfill dams in my country. The power station is equipped with three 400,000-kilowatt Francis turbine generator units with a total installed capacity of 1.2 million kilowatts. After completion, the average annual power generation is approximately 4.732 billion kilowatt-hours, which is equivalent to saving approximately 1.66 million tons of standard coal every year. It will effectively ensure the "green" The "Henan DC" ultra-high voltage transmission channel delivers power at full capacity, providing strong support for promoting the large-scale development and application of new energy in Qinghai Province and building a clean energy base in the upper reaches of the Yellow River.
"The 설계 최대 댐 높이 의 더 전원 스테이션 댐 is 150 미터, 및 더 최대 댐 길이 is 354.66 미터. The 합계 충전 볼륨 의 the 암석채우기 댐 is 4.06 백만 입방 미터. 그것 툭 a 합계 의 13 개월 에 완료 the 채우기. 중 이 기간, 우리 개최 현장 특별 회의 시작 시간 끝 시간. The whole process of pouring progress and quality is tracked, overcoming difficulties such as difficulty in arrangeing mining roads due to the steep terrain of the material site, high traffic safety risks in transporting high-strength dam materials, and unstable material source quality affecting the normal filling of the dam body, ensuring optimal construction. The construction plan runs throughout. " Xu Jianjun, 비서 의 당 위원회 및 대리인 일반 관리자 의 the 엔지니어링 건설 지점, 말했다.
From the official start of construction on December 26, 2021, the closure of the dam and the closure of the embankment on 12월 28, to the concrete pouring 의 the 최초 창고 의 the 댐 on 9월 27, 2022, the rockfill dam was filled to 2,600 미터 10 일 앞서 of 일정 on 12월 20. 이후 이 년, the 고정자 의 the 처음 단위 있었다 성공적으로 게양 에 11월 30 이 년. 이후 이 년, 양취 수력발전 역 있다 찍은 또 하나 밟을 향하여 목표 의 퍼팅 에 작업 및 생성 전기.
"Currently, the Yangqu Hydropower Station is at the peak period of civil engineering construction and mechanical and electrical equipment installation. In addition, it is winter and it is the end of the year and the beginning of the year. During the construction, we actively adopted the measures of erecting insulation sheds, covering insulation quilts, producing thermal concrete, etc. Regarding winter construction measures, strengthen overall coordination and coordination with all participating units, strictly implement the 'three inspections and one inspection' system for construction operations, accurately investigate and manage construction safety hazards and operational risks, and make every effort to ensure that project construction is advanced on schedule with high quality." Engineering Construction Branch Engineering Zhang Fenghua, director of the department, said. All participants will continue to work together to build the Yangqu Hydropower Station into a "safety project, ecological project, smart project, and high-quality project."
"트랜스포머" 재생 an 중요한 역할 in the 건설 of Yangqu 수력발전 역. First of all, "transformer" is one of the key equipment in the power system of hydropower station. It is responsible for boosting or reducing the voltage of the electric energy generated by the generator to meet the needs of different voltage levels. At the Yangqu Hydropower Station, "transformers" step up the low voltage produced by the generators to the voltage levels required by high-voltage transmission lines to carry power to distance areas.
Secondly, 더 "변압기" IS 또한 사용 에 조절 안정성 의 전압 및 전류. 동안 작동 의 수력 발전 스테이션, 더 "변압기" CAN 자동 조정 일치 에 필요 의 전원 시스템 및 작동 상태 의 발전기 설정 에 보장 안정 출력 의 전압 및 전류. 이 이 중요한 보장 안정 작동 의 더 전원 시스템 및 신뢰성 의 전원 공급.
In addition, "transformers" are also used to realize grid connection and disconnection operations of power systems. During the grid-connected operation of the hydropower station, the "transformer" can connect or disconnect the generator set from the grid to realize the grid-connected or decoupled operation of the power system. This is of great significance to ensure the stability and flexibility of the power system.
In short, "transformers" play an important role in the construction of Yangqu Hydropower Station. It is one of the key devices in the power system of a hydropower station. It is responsible for boosting or reducing the voltage of the electric energy generated by the generator, regulating the stability of voltage and current, and realizing grid connection and decommissioning operations of the power system.
