High temperature, this summer's most "hot" keywords. In the unusually hot weather that lasted more than two months this summer, the electricity load in East China has far exceeded that of the peak load in 2004. Continued high temperature raises the grid load, bringing stability to the regional power grid test. "Pumped storage power station has become the peak during the summer, East China Power Grid is the most important backup power protection." This is the East China Power Grid Control Center, Deputy Chief Hu Hu on the power supply protection evaluation of this summer. Among them, just put into operation less than a year of Anhui Xiangshuiian pumped storage power station to the power supply to produce a beautiful "answer sheet." Efforts to peak East China East "roasted" After six years of construction, on November 17, 2012, one of the backbone peak power sources of East China Power Grid and Anhui Xiangshuijian Pumped Storage Power Station were fully put into operation. The pumped storage power station with a total investment of 3.8 billion yuan is the first pumped storage unit in China that has independent intellectual property rights and designs, manufactures, installs and debugs domestically. The successful completion of the pumped storage power station completes the development of China's pumped storage Power station technology blank. "Just put into operation, to meet this year's East China high temperature, power tight test .Footily, the beginning of our great pressure." Anhui Wei water Jiangyin Pumped Storage Co., Ltd. Wei Wei, general manager, told reporters, "However, We have fully prepared to fight a tough battle for domestic pumped storage power station. " The total installed capacity of 1 million kilowatts, designed annual generating capacity of 1.762 billion degrees. Anhui Xiangshuijian Pumped Storage Power Station was put into operation and played a significant supporting role in ensuring the smooth operation of East China Power Grid. From July 1 to September 10, Anhui Xiangshuijian Pumped Storage Power Station started 319 times of power generation and started pumping 221 times, with a success rate of 100%. The plant developed a summer peak special equipment inspection program, the division of key inspection equipment and regions; arrangements for maintenance and maintenance personnel every 1 hour record the main transformer oil temperature, turbine vibration and thrust bearing temperature changes; on-site duty every The number of inspection trips increased to 3 times to record changes in data; production personnel were on-site standby, timely handling of equipment anomalies and the pneumatically-actuated features of pumped storage units were given full play. While guaranteeing the supply of power, the plant always adheres to the principle of safety first, strengthens risk management and control and enhances safety control. In the first half of 2013, the Company's overall safety and security situation remained stable. As of August 31, the annual safety production was 243 days with a continuous safety production of 2,459 days. "Pumped storage power station indeed played a significant role." In the national network Anhui Electric Power Company Control Center Zhao Xiaochun, deputy director, East China Power Grid, including water Shuijian pumped storage power station, including five large pumped storage power station, enhanced The peak load capacity of East China Power Grid is an important part of the balance between supply and demand in the summer. Under the condition of high temperature and heavy load, failure of any one generating unit will have a tremendous impact on the normal operation of the power grid, and the flexibility of generating electricity by a pumped storage power station makes it a reliable emergency power source. "Pumped storage power station has become the peak during the summer, East China Power Grid is the most important backup power protection." Hu said in an interview, said July 9, the highest temperature in East China generally more than 37 degrees Celsius, 40 degrees Celsius Weather more than 14 days, East China Power Grid began to enable pumped storage unit day "two pumping three fat" mode of operation. In addition to pumped storage during the normal early morning hours when the electricity is trough, there is an increase of light load during the period from 5:30 pm to 8:00 pm to raise the power generation capacity of the late peak and balance the power supply gap of late peak load. Together with the other four pumped storage power stations, the Xiangshuijian Pumped Storage Power Station can add 2.4 million kilowatts to the East China Power Grid during the late peak period, effectively balancing the power shortage during the late peak period. Deep plowing of experimental units of domestic units "Combined with the natural conditions of Xiangshuijian Pumped Storage Power Station, the unit of power station adopts the way of bidding for the bidding and purchases between Harbin Electric Machinery Co., Ltd. and Dongfang Electric Co., Ltd., independently designed and manufactured by HEC or Dongfang Electric Co., Ltd., This is in 2006, the National Development and Reform Commission of Anhui Xiangshui Jian pumped storage Power Plant project approval, "said Lin Yongliang secretary," eventually won the bid by Kazakhstan. " Anhui Xiangshui Jian also became the first domestic pumped storage power station. Wu Yao-fu, deputy general manager: "As a pilot field, Xiangshui stream is responsible for consolidating the pumped storage power plant equipment and technology introduction of the results, the pumped storage power plant localization responsibility, through the summer peak summer practice, Pumped storage power station unit efficiency of 78% or more. " In fact, the built Xiangshuijian pumped storage power station has become a fine project that is getting brighter and brighter. The main and auxiliary facilities of the power station are independently designed and manufactured by China. It is the first pumped storage power station in China to fully realize the localization of equipment. , Marking the construction of China's pumped storage power plant into the main and auxiliary equipment design, manufacture a new stage of localization. For this fully domestic storage plant units, Xiangshui people clearly aware of the burden on the shoulders. Xiangshuijian power station unit commissioning time is not long, the unit status is not stable, the unit more defects in order to promptly eliminate defects and ensure safe operation, operation and maintenance sub-field strictly enforce the ON-CALL on duty system in the event of defects can be 15 minutes Rushed to eliminate the scene, two types of defects within 24 hours to eliminate. On some occasional flaws, field professionals organized a thematic discussion to determine the treatment options and follow-up rectification measures, while giving top priority to other similar issues to be investigated to ensure that similar problems can be completely solved. As of August 31, 2013, there were 34 defects of more than three categories found in the whole plant, including one of the two types of defects and 32 of the three types of defects, all of which were completed on time and the rate of elimination was 100%. While doing a good job eliminating and eliminating the work, the operation and maintenance sub-units conscientiously do a good job in the work of unit inspection. According to the new situation of the equipment, the inspection items are rediscovered and a new inspection form is drawn up. For the seizure of the isolation operation and maintenance work using the exchange and exchange roles to complete. Do not miss any hidden dangers, is the power plant to ensure the safe operation of an important starting point. The power station in strict accordance with the new source company "hidden trouble investigation and management approach" on the whole plant production equipment and facilities to carry out investigation and management of hidden dangers. In accordance with the spirit of troubleshooting and routine work, the Company implemented dynamic management and timely completed the assessment of hidden dangers and establishment of archives so as to achieve "omnidirectional coverage" and "closed loop of the entire process." According to statistics, in the first half of this year, the power station completed 17 hidden control measures and closed-loop inspection, and 7 projects under control. In actual work, the responsible persons in all aspects have also carried out key special inspections according to special weather, major power-saving tasks and peak summer, leaving no one potential safety hazard and ensuring the safe and stable operation of equipment and power grids. To the "operation and maintenance integration" to be effective In fact, the experimental task undertaken by the Xiangshuijian Hydropower Station as a pilot field has more to do with it. Implementation of integration of operation and maintenance, the power plant according to the requirements of the new source, and actively explore practice. The implementation of integrated operation and maintenance is the implementation of the State Grid Corporation "three sets of five" system construction and management requirements. Xiangshuijian company take the initiative to assume the important task of the pilot, in the early stages of production to create the conditions to promote the implementation of operation and maintenance integration. In addition to the organization of the company, operating shifts and other methods were adjusted accordingly, and re-divided and clear equipment owners, but also the use of 1 # unit B repair, 4 # machine Coal Boilers,Coal Fired Boiler,Coal Steam Boiler,Cfb Coal Fired Boiler Jinan Boiler Group Co., Ltd. , https://www.shandongjinanboiler.com
