Under the circumstances that the scale of wind power installed capacity is continuously compressed and the development of superior wind energy resources is exhausted, the development of market-oriented low wind speed wind power projects is gradually replacing the construction of large resource-oriented wind power bases, but this also proposes to owners and equipment manufacturers. Higher requirements.
In 2017, Luoyang Yiyang Huadian Fuxin Shipyard Wind Farm (hereinafter referred to as 'Chengcheng Wind Farm') operated at full capacity throughout the year. At an annual average wind speed of 5.58m/s, the annual utilization hours of the unit reached 2567 hours. The average value of all wind farms operating in full capacity in Henan Province is 464 hours higher. The shipyard wind farms have achieved such high annual utilization hours in areas where wind resources are not dominant. The best business is sure.
Then, how do Huadian Fuxin, the owner of the Chuancheng Wind Farm, and Mingyang Intelligent, the equipment manufacturer, do it? Recently, the reporter walked into the Chuancheng Wind Farm with the 'Best Wind Farm' sponsored by Wind Energy magazine, exploring 2567 The mystery behind the hour.
Low wind speed units help achieve the goal of 'two high and one low'
The location is selected, the model is selected, and more electricity can be sent.
Tao Jingtao, deputy general manager of Henan Huadian Fuxin, said: 'Henan Luoyang wind resources are not very good. Under the premise of safety first, priority should be given to economics to ensure that wind turbines can achieve the best wind energy absorption at low wind speeds to ensure the most power generation. Excellent, you need to choose the most suitable model. Mingyang intelligent low wind speed model can meet the needs of the ship city wind farm.
According to the general manager of Mingyang Intelligent Henan Region: 'This low wind speed model adopts optimized pneumatic airfoil and fourth generation advanced control strategy in design, which can reduce load and increase power generation, with good low The voltage traversal capability can achieve the goal of two high and one low (ie high power generation, high reliability and low power cost) to a higher degree.
However, the high performance of the unit itself can only be stimulated by good operation and maintenance. At present, the wind turbine of the Chuancheng Wind Farm is still in the 5-year warranty period, and the operation and maintenance of the latter is jointly completed by the owner and the equipment manufacturer.
He Tianya, the captain of the ship wind farm, said: 'The intelligent field technicians of Mingyang have brought us technical support in the later operation and maintenance. They have carried out a series of techniques for the unit on the characteristics of low wind speed wind farms in the mountains. Renovation. ' According to He Tianya, Mingyang Intelligent installed the fan vibration online monitoring device for the unit, which can detect defects in time and avoid the expansion of the fault; add an automatic fire protection system for the unit, which can protect the safe operation of the equipment; The fan-free climber is installed, which can improve the operation and maintenance efficiency.
The upgrading of hardware has laid a good foundation for the shipbuilding wind farm. Then, in a highly intelligent industry, how does big data work?
Develop a smart fan solution, explore predictive maintenance, achieve ten minutes response
Tao Jingtao said: 'The achievements of the ship city wind farm to achieve such a high number of years of use are inseparable from the two intelligent operation and maintenance experience - '10 minutes response mechanism' and 'predictive maintenance plan'. ' It is understood that Mingyang Intelligent Providing a smart fan solution for the wind farm, the fan operation data is connected to the Mingyang Smart Energy Big Data Application Center, which can monitor the core indicators of each unit's key components in real time, thus obtaining detailed operation information of the unit and For comparison, analysis, 'ten minute response mechanism' and 'predictive maintenance plan' are realized through big data analysis.
'Mingyang Intelligent provides a matching power forecasting system for the shipyard wind farm. The system can predict the short-term and 24-4 hour ultra-short-term power of 24 wind turbines in the wind farm. Supported by the support of the big data center, Comparing online real-time monitoring data and historical experience database, the power prediction system can predict and evaluate the fan status and performance; realize planned shutdown maintenance through fault warning work orders, periodic inspection periodic maintenance, etc., thereby prolonging the use of large components. Lifetime' Tao Jingtao introduced, 'In addition, if the wind turbine is out of service, the big data center's early warning platform will transmit the information to the EDM, and then the central control room will transmit the information to the wind farm operation and maintenance personnel through telephone, QQ and other contact information. Information, personnel responded for ten minutes; while dealing with problems that cannot be solved temporarily, Mingyang intelligent field technicians will respond to the control degree of Mingyang shutdown pipe and apply for remote assistance to ensure response and resolution within 15 minutes, thus greatly reducing the fan. The wind of the fault'.
Integrated management of personnel on both sides, improving work efficiency, achieving win-win cooperation
The implementation of the program is inseparable from the cooperation of personnel. He Tianya said: 'Huadian Fuxin and Mingyang Intelligent jointly promote lean management, improve work efficiency, complement each other, and win-win cooperation to maximize the performance of the unit.'
According to He Tianya, in terms of staffing, Mingyang Intelligent has 4-5 field technicians stationed in the wind farm, daily response to fault handling and completion of inspection and maintenance, and can handle 24-hour shift duty when handling faults. These personnel have also been included in the wind farm operation and maintenance, maintenance team, to achieve integrated management. He Tianya said: 'Mingyang intelligent field technicians and the ship city wind farm team to participate in the morning class, safety activities, learning wind power accidents Cases, lack of training, maintenance and troubleshooting, etc., they are integrated with wind farm maintenance personnel, helping each other in the work, promoting the exchange of work information, enhancing the tacit cooperation between work feelings and work, and improving Daily maintenance and maintenance work efficiency. '
Subsequently, Tao Jingtao introduced the experience of lean management, namely the 'assessment reward system'. Tao Jingtao said: ''The assessment reward system' is also called 'equipment to people, electricity to the machine'. Equipment to people, that is, every fan Have their own 'master', 'master' is responsible for the reliability and power generation of the equipment; the power to the machine is to make a monthly power generation plan by marking the power generation of each unit for the first two years. In order to motivate the employees' responsibilities and enthusiasm, ensure the health of the equipment and generate more electricity, so as to ensure the power generation and utilization hours of the unit.
When talking about whether the follow-up project will cooperate with Mingyang Smart, Tao Jingtao said: 'In 2017, the average annual utilization rate of the shipbuilding wind farm unit reached 99.41%, and the actual power generation reached 123 million kWh, far exceeding the year. Designed to generate a target of 91.69 million kWh. '
