During the ten years of construction and operation of wind farms, the wind power industry experienced a process of cooling from hot to cold and then turning from heat to cold. Wind power generation has arisen due to clean and environmental protection, improved climate, and energy conservation and emission reduction. It has stagnated at the current situation of poor load support capability, random power output, and insufficient power consumption capacity. Summarizing the experience of wind power development in the past ten years is very necessary for the already established wind power industry. On the one hand, we must maintain the stable and stable state of operation of established wind farms, and on the other hand, we must further promote the expansion of wind power industry scale and industry. Upgrade plan strategy.
The problems caused by the poor status of the domestic wind power industry include the following aspects:
1. The global economy is in poor condition, and investment in wind power is decreasing;
2. The instability and uncertainty of wind energy power make it unable to become a supportive power system in a grid that requires extremely strong safety and stability, but can only be accompanied by auxiliary power based on thermal power and nuclear power load. This inherent congenital defect has always been an unstable factor or a psychological concern in the current operation of the power grid;
3. As an electric power load transmission and distribution grid, the construction speed of the transmission network in the area with rich wind lags behind the speed of production of wind power projects. This fact contrasts sharply with the scale of the explosive expansion of wind farms in China in recent years. The lack of roads leads to inefficient and wasteful investment.
4. Domestic industrial policies and industry plans cannot point out a clear path for the current development of wind power.
From the point of view of the difficult recovery of the international economic situation, investment per capita adopts a more conservative investment strategy and the new energy industry continues to shrink. The wind power trade between countries has also been blocked by trade protectionism, making domestically-made wind power equipments nowhere. From the perspective of the domestic wind power industry, the owners of wind farms have been affected by three major unfavorable factors such as power curtailment, zero CDM prices, and subsidies for renewable energy, which have caused a sharp decline in economic efficiency. The wind power equipment manufacturing industry has caused severe overcapacity due to explosive expansion in previous years. As many as 70 to 80 wind power equipment manufacturers have homogenized competition, rapidly lowering equipment prices and severely reducing profit margins! Coupled with the current poor economic performance of wind farms, the wind power construction projects are drastically reduced, and the current economic situation of wind power equipment manufacturing industry is extremely bleak. Most manufacturers will be shuffled. The poor economic conditions of equipment suppliers have brought difficulties in maintaining the quality of after-sales services, inadequate supply of spare parts, and lack of on-site technical support personnel, which has caused a very negative impact on the operating status of most wind farms that are still under warranty. It seems that we wind power people have to face the reality, to meet the challenges, will have completed the construction of wind power projects, the survival of equipment operators to improve equipment quality and service levels, waiting for the opportunity for further development.
For wind power producers - wind power operators, we must face up to the inherent shortcomings of wind power itself. Its randomness, counter-regulation, and instability are indeed difficult to become the main power source in the power grid. The sentence is not quite exact: “Wind power is a healthy dish, but it cannot be a staple food!†How to eat this dish well and let more renewable, clean wind power integrate into the big grid is our wind power company and Grid companies need to study and solve problems in depth. From the perspective of wind power companies, running a good wind farm is not only a matter of doing a good job of wind turbines, but it also includes the operation of the collector circuit and substation equipment of wind farms. The general characteristics of wind farms are located in areas with poor environmental conditions and remote areas such as coastal areas, hills, grasslands, and Gobi. Wind power equipment and power transmission and transformation equipment are greatly affected by natural conditions. At the same time, the number of wind turbines is large and scattered. To ensure the safe and stable operation of wind farms and continuous power supply, the management difficulty and workload are indeed higher than other power systems. To do a good job in the production and operation of wind farms is to do two things well on the basis of providing stable and smooth power transmission support for the wind farms: First, with the cooperation of wind power equipment suppliers, do a good job of adaptability of the grid and control of the power of wind turbines As well as the quality of power to improve the power grid support capabilities of wind power; second is to develop a strong, professional and professional operation and maintenance team to maintain and operate the power transmission and transformation system in the venue, often the fault is not in the wind turbine. But the reliability of the equipment in the line and substation equipment is the key to improving the stable performance and grid support capability of the wind farm.
For power grid companies, how to solve the problem of matching power grid construction with wind power construction, and effectively solve the load regulation capability, and absorb more wind power is the basis for promoting the sound development of the wind power industry.
From the situation of wind power integration in the Zhangjiakou area for several years, we have found a situation, but I do not know whether this situation is representative?
Welded Wire Mesh
It is widely used as machine protecting mesh, garden or residential fence and livestock cage in industrial or agricultural area. In addition, according to different flexibility, welded wire mesh can be divided into 2 types: welded mesh roll and welded Mesh Panel. The former has better flexibility.
