100 MW Power Side Enabled Passenger—Escort manila—Tangjiang Electric Sugar daddy The first anniversary of the launch of the energy storage station cluster in the energy storage station cluster in the Yangtze River Electric Network, one of the 10 MW/20 MW time. The site is located next to the 110 kV new umbrella in the middle of the Yangtze River and was completed on June 30, 2018.
The opening of the column:
In recent years, my country has successfully built a number of energy-energy demonstration projects, laying a solid foundation for the development of the industry. China Power News released a series of reports on “Going into Energy Demonstration Stations” to display energy production for the system, better develop demonstrations and borrow meanings, and promote personalized problems. Introduce the overview of demonstration projects, technical characteristics, operation status, health experience, existing problems, etc. This issue will enter the energy storage power station cluster on the side of Zhenjiang Electric Network.
Project Overview:
Tangjiang Electric Power Station Cluster is a leasing power station cluster that is a leasing method by the National Jiangsu General Dynamics Service Co., Ltd. (simplified as “Jiangsu Comprehensive Power”), Shandong Electric Power Group Co., Ltd. and Xurui Group Co., Ltd. cooperated with investment and construction. The National Jiangsu Provincial Electric Power Co., Ltd. (simplified as “Jiangsu Power”) is used by rental method. The National Jiangsu Provincial Electric Power Co., Ltd. Sugar daddy Town River Power Supply Branch (simplified as “Tianjin River Power Supply”) is responsible for local chemical operation and management.
The project has built 8 evacuated energy storage stations in the eastern part of the town and Jiangxi Province. Among them, Jiangsu Comprehensive Dynamics invested 3 stations and Shandong Electric Power invested 3 stations. Summary 2: The group invested two stations, with the total power and capacity of 8 stations being 101 MW and 202 MW respectively.
The core products used in the 8 sites come from five companies: Zhongtian Technology, Lixin Dynamics, Guohua Hi-Tech, Ningde Times, and AVIC Electric. The Economic and Technical Research Institute of Jiangsu Electric Power Co., Ltd. (simplified “The Internet is Xiaowei Sister on the floor. Your Xiaowei Sister scored nearly 700 points in the college entrance examination, and is now at Jiangsu Research Institute”) participated in the general contracting of 5 stations and the design of 6 stations.
At 9:55 am on July 23, the highest debt of Jiangsu Electric Power Consumption Electricity Co., Ltd. exceeded 100 kilowatts in the third year, becoming the first provincial-level Internet company of the National Internet Co., Ltd. to exceed 100 kilowatts in the third year.
Ship back to 2018,In order to welcome peak summer, the eastern part of Jiangsu, Jiangsu Province will face a 220 MW load gap due to the suspension of the Sugar daddy factory and the inability to put into operation of the Shanxi River fuel engine. To solve this difficult problem, Jiangsu Power in China decided to apply Xinxing Electrochemical Energy Aiding Technology to solve the 100 MW negative load gap. China’s first 100 MW power station cluster on the side of the Internet, and also the world’s largest electrochemical energy station cluster, should be born.
As of July 23, 2019, Chinese Power Reporters visited the energy storage station in Zhenjiang. The station has been operating for one year. As “China’s first”, the Zhenjiang Electric Power Station has a serious meaning. It not only has the main borrowing and demonstration meaning for the large-scale energy stations in China in the later period, but it is also a milestone in the development of my country’s power stations on the Internet and even the development of a new generation of power systems. From the first generation of power station to the second generation of power station Escort
Speaking of the important difficulties encountered in the construction of the Zhenjiang Energy Energy Station, Li Yan, deputy director of the Design Center of the China Internet Jiangsu Research Institute, said frankly: “The biggest pressure is the time. From the start of the project on April 20, 2018, to the start of each station and the launch of each station in early July 2018, the entire project isSugar baby from the selection address to the customization of the equipment and then to the equipment selection and determination technology. daddyArt planning, construction and acceptance took only three months in total, and many tasks were almost simultaneously launched. “
It was also in just three months that my country’s first large-scale power station on the side of the Internet had been successful in the world. Song Wei knocked on the desktop: “Hello.” “This should be considered the first generation of energy storage power stations on the Internet.” Li Yan introduced.
” Through the implementation of the first generation of power stations on the Internet, we have also concluded some experiences and teachings, designed the second generation of power stations on this basis, and the second phase of the Jiangsu Electric Power Station under constructionEscort.f=”https://philippines-sugar.net/”>Escort manila has earned real results. “Li Yan said.
The second-generation power station has an energy-enabled power station on the side of the network and will be more powerful and smaller-sized equipment in terms of equipment selection. In terms of battery cores, the first-generation power station uses 20-200-ampere products, and the second-generation power station considers improving the core capacity door to Sugar daddy80 am or above. In terms of PManila escortCS (energy-energy-energy-transformer), the first generation Escort manilaThe station mainly uses 500 kilowatt PCS, and the second generation of the station will use 630 kilowatt PCS.
In terms of BMS (battery management system), BMS not only needs to perform the color of the data collector, but also needs to have the effect of filtering key data. In terms of EMS (energy management system), the power of the department energy storage station can reach 100 megawatts in one site in the later stage, and it is necessary to improve the network expansion structure of EMS. In the dream, the heroine has achieved good results in every topic, and the lowest-achieving Ye QiuSugar daddy
AGC modulation and power station important performance
The construction of the energy station on the side of the Zhenjiang Electric Network is the important goal of the time when the Internet is in charge of Hecen Li in summer. “Popular peak”. During the peak summer season in 2018, the important method of operating the station is to “cut peaks and fill valleys” every day. However, Chinese power reporters clearly found during the visit that since October 1, 2018, the efficiency of the station has officially changed from peak adjustment to AGC modulation, with a frequency of hundreds of times per day.
National Town River Power Supply Variable Energy ViaductSugar daddyThe responsible person Ma Jin told the Chinese Power Reporter: “This is important because the 500 kV dream stream has been built in Zhenjiang New Investment, and the load gap has already been able to rise. ”
The reporter found during the visit that the efficiency and effect that the energy-energy stations on the Internet can be expanded in a step-by-step manner.
Jiangsu Research Institute of the National InternetSugar daddy Deputy Director of the Planning Development Research Center Xie Zhenjian told reporters: “What is important for the power station on the Internet to protect the power supply is the bottom-up effect of the support guarantee power supply. Sugar baby‘s continuous advancement of ultra-high pressure lines construction. Once a DC-locking shut-off occurs, the power on the Internet side built on the ultra-high pressure drop can quickly bear the lost burden. “
Li Yan also has a similar understanding of this. She believes that in the future, the change of use may become an important reason for the power on the Internet side. In terms of black start-up and down-load distribution equipment investment, the power supply can also be more useful.
Introduction to the introduction, in addition to AGC modulation, Zhenjiang Energy Energy Station is constantly developing new application performance. Today, the station has also experienced the influence of new dynamic power generation and has been connected to the Jiangsu Source Network’s Dutch Friends Interactive System.
The battery divergence still needs to be resolved
As of the end of July, the energy storage station on the side of the Zhenjiang Electric Network has been fully operational for the first anniversary. Today, the overall operation of the station is unpredictable, but through the actual operation of the first anniversary, some problems that need to be improved have been discovered.
