At 00:58 on May 27, Unit 9 of the fourth phase expansion project of Zheneng Jiaxing Power Plant was successfully connected to the grid for the first time, and the system parameters of the unit were normal and stable, laying a solid foundation for the subsequent 168-hour trial operation and official operation of power generation.

As a key project of clean coal power in Zhejiang Province during the 14th Five-Year Plan, the fourth phase expansion project of Zheneng Jiaxing Power Plant has been included in the provincial "first establishment and then reform" clean and efficient supporting power supply project, the provincial energy "green and stable" and the expansion of effective investment "thousands of trillions" project, and the two units of the project are constructed in phases. Among them, the No. 9 unit of Zheneng Jiadian Phase IV will build a 1000MW ultra-supercritical secondary reheat coal-fired power generation unit, and the pile foundation will start in September 2023. After the unit is put into operation, it will provide a strong and reliable energy guarantee for Zhejiang Province's energy supply during the peak summer this year, effectively alleviate the pressure of the medium and long-term power gap in Zhejiang Province, and provide stronger power support for the energy security of the Yangtze River Delta and the high-quality development and construction of a common prosperity demonstration zone in Zhejiang.

In order to ensure the smooth completion of the first grid-connected work, Zheneng Jiadian made careful deployment and scientific arrangements, actively organized commissioning and scheduling, coordinated the forces of all parties, mobilized all resources to fully promote the construction of the project, and implemented the responsibility goals at all levels with the determination of "mission must be achieved". The project construction team has a unified ideology, firm beliefs, and strong execution, and strongly guarantees the construction of Unit 9. The backbone personnel of the participating units worked hard and tightened the strings, and completed a series of pre-grid tests such as generator short circuit, no-load, and excitation adjustment system with high quality and high efficiency.

At present, the project construction team is in full swing to carry out more than 40 test projects such as the first post-grid connection electrical test, coordination and optimization disturbance test, and important auxiliary equipment RB test, and will complete the complete set of start-up and commissioning work with high standards and strict requirements, and make every effort to sprint the unit to be put into operation as scheduled.

The successful grid-connected power generation of Unit 9 of the fourth phase of Jiaxing Power Plant once again demonstrates the outstanding strength of Zhejiang No.2 Construction in the field of power construction and civil engineering. Since 1992, Zhejiang No.2 Construction Electric Power Construction Branch has successively undertaken the first, second and third phases of Jiaxing Power Plant. The first phase of the project won the "Qianjiang Cup", the second phase won the "Luban Award", and the third phase won the "National Excellence Gold Award", empowering new development with ingenuity.(This article is from the official website of Seetao www.seetao.com.
