Converting the kinetic energy of wind into mechanical kinetic energy and then converting mechanical energy into electric energy is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity.

At present, the resources of wind power projects are in short supply, and the disadvantages of coal power generation are increasingly exposed, which not only causes serious pollution, but also wastes a lot of resources. In order to solve this problem, some renewable energy sources have been developed and utilized more, and wind energy, solar energy and geothermal energy have been rationally utilized. Among them, wind power projects have played an important role, which can meet people's electricity demand as much as possible without polluting the environment. Therefore, wind power generation projects have been widely valued and analyzed.

1 preface

There are various risks in the installation of wind power projects, including personnel and policies, natural disasters, equipment technology and installation management, which will affect the installation quality of wind power projects and the benefits of wind power construction. Therefore, accurate risk analysis and comprehensive grasp of existing risks can strengthen the management of all aspects of wind power projects, improve the installation management quality of wind power projects, and ensure that wind power projects can play an important role and create greater value.

2 Wind power project installation project risk analysis

2. 1 Risk of policy change

The wind power generation project has just started. In addition, wind power projects are encouraged by the state. The state supports wind power projects and has issued a series of policies to promote the development of wind power project enterprises. For example, give economic subsidies to wind power application projects and give some tax incentives. Through these policies, the development enthusiasm of enterprises is higher and the wind power projects are better, but the society is constantly changing and the national policies are constantly changing. Once the policies related to wind power projects change, it is likely that wind power project units will be caught off guard and do not know how to deal with them, resulting in policy risks of wind power projects, which is not conducive to the development of wind power projects.

2.2 Employee risks

Employee risks are common. When the staff's construction technology is not mature and the technology is not up to standard, it is easy to generate personnel risks and affect the installation of wind power projects. Employee risks are mainly reflected in two aspects. On the one hand, there are risks in the process of wind power equipment installation procedures, and the installation project of wind power projects is special. The maintenance, installation and operation of wind power equipment are all aerial work, which not only increases the strength of workers, but also has great risks, which hides great risks [1]. On the other hand, the staff's own problems, such as immature construction technology, insufficient technical ability, insufficient knowledge reserve and irregular operation, will affect the installation quality of wind power projects and cause personnel risks.

2.3 Construction, installation and operation risks

During the installation and operation of wind power generation projects, failures will inevitably occur. The risks of construction, installation and operation are mainly reflected in the following aspects. First, if the maintenance personnel can't find it in time, the forced operation of the wind power project will lead to serious damage and immeasurable losses of the wind power project. Second, in the case of wind power equipment aging or component damage, the whole unit can't operate normally, and there is great operational risk. Thirdly, in the case of intermittent operation of wind power equipment, it will affect the safety and stability of the power grid and produce construction and installation risks [2].

2.4 Technical risks of equipment

The technical risk of equipment is the main risk form in the installation of wind power projects. As we all know, China's wind power project construction technology has just started, and it is not mature enough compared with western developed countries. At the same time, wind turbines are developing to large scale, which puts forward higher requirements for technology. The identification system of wind power projects in China is not perfect, which has great security risks. Therefore, the wind power project technology itself has great risks.

2.5 Natural disaster risk

Wind power engineering equipment depends on wind energy and natural resources. Therefore, natural disasters are natural enemies of wind power engineering equipment, which will produce natural disaster risks and affect the normal operation of wind power equipment. The risks of natural disasters are mainly manifested in two aspects. On the one hand, after natural disasters, not only will it take a lot of manpower, material resources and financial resources to repair, but also the normal operation of wind power equipment will be affected, resulting in huge economic losses. On the other hand, wind power equipment is mostly exposed to the air, which will be affected by various natural disasters, such as sandstorms, typhoons, lightning, etc., which will destroy wind power projects, generate natural disaster risks, and affect the installation and operation of wind power projects.

3 Countermeasures to reduce the installation risk of wind power projects

3. 1 Countermeasures against the risk of policy change

Policy risk is an untransferable risk. Wind power project units can only be implemented under the guidance of relevant policies, and conduct in-depth research on national policies and national plans for wind power enterprises to ensure that wind power projects can develop smoothly and maintain a good development trend with the support of national policies. At the same time, they also need to attract professionals to analyze and predict the national economic situation and policy changes, and strive to make preparations in advance, so as not to be overwhelmed by policy changes and affect the operation of wind power projects.

3.2 employee risk solutions

The wind power project is special, which requires the staff to have good professional quality, solid professional knowledge and solid technical ability. Therefore, the solution to employee risks is to intensify training, and relevant departments can effectively train employees through organizing training and education, so that employees can understand their work contents and responsibilities, improve their moral quality and enhance their comprehensive ability [3]. Organize employees to go out to study, constantly learn new knowledge and technology, and improve the overall quality of employees. In this process, it should be noted that many wind power projects are high-altitude operations with high risks, so it is necessary to take safety protection measures to reduce the risks of operators and ensure their life safety.

3.3 Solutions to construction, installation and operation risks

The installation of wind power projects has high technical requirements for the installation unit. Therefore, it is necessary to understand the installation unit first, check the installation unit to ensure that it meets the relevant standards, and then allow its installation, ensure the installation quality and reduce the installation risk. Secondly, the relevant units also need to improve the management system, guide and supervise the wind power projects, reduce operational risks, and prevent the normal operation of the equipment from being affected when the equipment fails.

3.4 Countermeasures for Technical Risks of Equipment

Wind power projects have high requirements for weather. In the construction stage of wind power project, we should start with site selection, increase technical input in equipment selection, and ensure the rationality of site selection and the scientificity of equipment selection. The solutions to technical risks of equipment are mainly reflected in project site selection and equipment selection. In the process of project site selection, it is necessary to pay attention to the windy and windy addresses all the year round, and choose areas with little or no wind, which loses the significance of wind power project construction. In the process of equipment selection, it is necessary to ensure that the equipment quality is qualified and meets the design requirements, and that the equipment meets the certification standards and obtains qualification certification.

3.5 Solutions to natural disaster risks

Although the risk of natural disasters is inevitable, it can be effectively prevented and minimized. Therefore, to solve the risk of natural disasters, we need to do the following: First, do a good job of prevention in advance, analyze natural disasters according to the weather forecast and weather conditions, and take preventive measures when natural disasters come, so as to minimize the impact of natural disasters and reduce the risk of natural disasters. Second, establish a professional maintenance team to do a good job in the maintenance and prevention of wind power projects to ensure the normal operation of wind power projects. Third, the occurrence time of natural disasters is * * *, and the staff can sum up the laws of natural disasters based on years of experience and formulate a set of practical and effective preventive measures to reduce the risk of natural disasters and ensure the normal operation of wind power projects.

4 conclusion

At present, the problem of energy shortage is increasingly exposed. Strengthening the investment in wind power projects, comprehensively grasping the engineering risks of wind power projects and ensuring the installation quality of wind power projects are of great significance for alleviating the energy crisis and creating greater economic benefits. By implementing targeted risk management and control measures, the installation risk of wind power projects can be reduced as much as possible and the benefits of wind power projects can be improved.
