After the completion of the China ASEAN Free Trade Area in 2010, the negotiation on upgrading the free trade area has been completed by 2015

huangweijing, member of the Standing Committee of the Party committee and Secretary General of Guangxi Zhuang Autonomous Region, said at the press conference that the current East China International Fair is richer in content and has more business opportunities than previous exhibitions. China's products in this exhibition will highlight informatization, intelligence, green and energy conservation, and promote more comprehensive economic and trade cooperation through scientific and technological innovation and upgrading; There are more well-known brand goods from ASEAN countries than in previous years. There are 8 ASEAN countries' pavilions, and the the Belt and Road international exhibition area has more exhibits from participating countries

it is understood that the Expo will continue to set up an exhibition area for power equipment and new energy to display China's high-quality power equipment and new energy enterprises. This exhibition area is tailored for businesses in ASEAN countries and meets the needs of ASEAN power enterprises to purchase China's power equipment and introduce China's advanced power technology and new energy technology. The exhibition area is rich in content

it mainly includes power generation equipment, transmission/distribution/transformation equipment, wires and cables, instruments and meters, electrical automation equipment, etc

there is great potential for energy cooperation between the two sides

in recent years, ASEAN countries have witnessed rapid economic development and rapid growth in power demand. The advantages of China's power technology and equipment have provided strong support for ASEAN countries. The agreement between the two sides' supply and demand has doomed the huge potential of cooperation between the two sides in the power industry. In order to meet the increasing demand of ASEAN businesses for new energy technologies, this exhibition will continue to display China's latest research achievements in new energy technologies, including solar energy, wind energy, nuclear energy, biomass energy and energy-saving and emission reduction technology projects. In addition, participants can also find ideal project and engineering partners at the exhibition

due to the adjacent geographical location, the power equipment developed by China has higher adaptability in ASEAN countries. China's power generation equipment, power transmission and transformation equipment, electrical automation equipment and other products are not only superior in quality, but also have unique advantages in manufacturing cost, labor cost, logistics cost and price factors compared with similar products in Europe, America and Japan, which are loved by buyers in ASEAN countries. Therefore, this exhibition area receives much attention in the East China International Fair every year. According to relevant statistics, the trade volume of power equipment reached about 600million US dollars in the 11th Expo alone

this year is an important year to promote the construction of the "the Belt and Road". Huang Weijing pointed out that this ASEAN Expo will take infrastructure construction as the guide, equipment supply as the center, scientific and technological innovation as the driving force, metallurgy and building materials as the extension, and financial services as the support to solidly promote international production capacity, equipment manufacturing and economic, trade and investment cooperation between China and ASEAN and countries along the "the Belt and Road"

fine operation and maintenance has enabled the wind farm to generate more power than expected

Mingyang intelligent and Henan Huadian Fuxin have jointly created a low wind speed wind farm model

Yu Haijiang

among all the wind farms that have been put into operation in Henan Province, Luoyang Yiyang Huadian Fuxin Chuancheng wind farm (hereinafter referred to as "Chuancheng wind farm") is not the best in terms of wind resources, but its annual power generation is far higher than expected

recently, the 2018 "most beautiful wind farm" activity sponsored by wind energy magazine went to Chuancheng wind farm to explore the mystery behind its higher than expected annual power generation

2017, Chuancheng wind farm operated at full capacity throughout the year. Under the annual average wind speed of 5.58 M/s, the available hours of units were 2567 hours, 464 hours higher than the average 2103 hours of all wind farms operating at full capacity throughout the year in Henan Province, far higher than the planned hours

"two high and one low" and fine operation and maintenance have achieved remarkable results.

"Chuancheng wind farm is the first wind power project in Luoyang, with a construction capacity of 48 MW and installed with Mingyang intelligent low wind speed model." Kuang Yan, Henan regional general manager of Mingyang Intelligent Energy Group Co., Ltd. (hereinafter referred to as "Mingyang intelligent"), said that this model has national independent intellectual property rights and can achieve "two high and one low", that is, high power generation, high availability and low cost. In terms of design, the optimized aerodynamic airfoil and advanced control strategy are adopted, which have good low-voltage ride through capability, reduce load, and increase power generation

it is understood that this model is equipped with the self optimization control strategy independently developed by Mingyang intelligent, the independent pitch control strategy of asymmetric load sector and the strong gust anti overspeed control strategy. This system can estimate the change of wind speed according to the external wind speed and the model, and automatically find the optimal pitch angle, optimal gain and optimal CP value, so as to ensure the reliable operation of the unit and improve the power generation efficiency

in addition to utilizing the unit's own performance on super large container ships, liquefied natural gas (LNG) ships and other high-tech ships, operation and maintenance is a key link to ensure the high reliability of the unit. In the opinion of hetianya, the director of Chuancheng wind farm, fine operation and maintenance is the main reason behind the popularity of the annual power generation and unit availability data of Chuancheng wind farm

"On the one hand, we have developed a series of measures for fine operation and maintenance. For example, we have included various early warnings and problems found in the operation of the unit in the maintenance plan in advance, and through wind power prediction, we have concentrated some maintenance on small wind days, so as to minimize the impact of unit shutdown on power generation. On the other hand, in addition to reaching the international advanced level of orthopaedic surgical robots and realizing the mass use of the whole machine technology in hospitals, it is clear that Yang intelligent's operation and maintenance service capability should not be underestimated. Mingyang intelligent timely optimizes the control strategy and improves the performance of the unit, including pitch optimization, yaw optimization, etc., to ensure that the unit operates at full capacity throughout the year. " Hetianya said. Ming Yang intelligent big data center escorts the fine operation and maintenance

"Ming Yang intelligent big data center can monitor the core indicators of the key components of each unit in real time, so as to obtain the detailed operation information of the unit, so as to achieve preventive maintenance and truly realize the state-based operation and maintenance." Taojingtao, deputy general manager of Henan Huadian Fuxin Energy Co., Ltd. (hereinafter referred to as "Henan Huadian Fuxin"), said in an interview with China Power News: "Henan Huadian Fuxin has developed a strategy of predictive maintenance, using small wind. 3. during the processing and storage of samples, it is necessary to avoid rusty days or windless days, conduct fixed-point maintenance of fans, and carry out hidden danger troubleshooting and defect elimination." According to the introduction, Mingyang intelligent big data center is the leading wind power data platform in China at present, which can realize the coordinated dispatching from meteorological prediction, wind turbine health monitoring and early warning, wind farm optimization operation, and wind farm group. Based on the intelligent prediction of wind, centralized monitoring can be realized, and few or no people are on duty, instead of investing a large number of O & M personnel in each wind farm; At the same time, the sub-health status of the unit shall be warned to achieve timely and preventive maintenance, rather than unplanned shutdown and waiting for component replacement after component damage. The monitoring system can also be used across platforms to ensure that the security of the system is not affected

"relying on the support of big data, through real-time monitoring and historical experience base, predict and evaluate the fan status, and realize planned shutdown and overhaul through fault early warning work orders, periodic inspection and periodic maintenance, so as to extend the service life of large components. For unplanned downtime such as sudden faults, through big data, issue fault work orders and fault reports in real time, so as to respond quickly and process quickly." He Tianya said

since its establishment, Mingyang intelligent big data center has been able to manage wind farm data in various dimensions, such as regions and models. The current status, real-time wind speed and real-time power of each unit, changes in wind speed and power of the wind farm in the past 24 hours, availability of the wind farm, KPI evaluation of wind farm operation, etc. these information can be quickly retrieved and displayed from the system, providing strong support for the analysis of the operation status of the wind farm

based on a large amount of data obtained by the monitoring system, through the establishment of mathematical models and the use of machine learning and other core algorithms, the unit health hazards and fault prediction are realized, and an early warning mechanism is established. Take preventive maintenance and repair, reduce unplanned downtime, avoid damage to major components and loss of power generation, and continuously improve the lean management capability of the wind farm. At present, Mingyang intelligent has established 70 parts and system early warning models to achieve full coverage of core parts such as gearbox, generator, main bearing and blade
