Detailed Description
Wind energy is one of pollution-free energy sources, and is inexhaustible. For coastal islands, grassland pasturing areas, mountain areas and plateau zones with inconvenient traffic, wind energy is utilized to generate electricity according to local conditions, and the economic benefit is considerable. Wind power generation is an important field of renewable energy development and is an important measure for promoting the adjustment of energy structures in China. The wind energy resources in China are rich, the construction of wind power projects is accelerated, and the method has important significance for adjusting energy structures and changing economic development modes.
The wind energy is 3 times of the wind speed, the difference of the wind speed is 1 time, and the difference of the wind energy is 8 times, so that the selection of a good wind power plant wind speed is of great importance. The selection of the site of the wind power plant plays a key role in the achievement of the expected purpose of wind energy utilization. Of course, the wind power plant also considers the conditions of power grid, traffic, environment, life and the like, but the wind energy resource is the most important.
After the macro site selection of the wind power project is determined according to the basic principles of wind energy resources, construction conditions and the like, the process of micro site selection of wind power is started
In the microscopic site selection process of the wind power project, designers need to comprehensively consider and analyze sites from two aspects of wind energy resources and construction conditions. The analysis of the construction conditions comprises the constraints of administrative conditions such as administrative boundary lines and protected areas and the constraints of natural conditions such as earthquakes and typhoons, and the analysis process needs the cooperation of multiple professional workers such as administrative staff, geology staff and environment-friendly staff.
In the analysis process, workers of each specialty generally only pay attention to condition factors related to the specialty of the worker, but do not pay too much attention to other specialties, and after the analysis results are finally summarized, due to insufficient communication of information, site selection of the wind power project can be caused to occur in an area which is not suitable for construction, and therefore modification and even re-establishment of the analysis process are caused.
Geographic Information Systems (GIS) are sometimes also referred to as "Geographic Information systems". It is a specific and very important spatial information system. The system is a technical system for collecting, storing, managing, operating, analyzing, displaying and describing relevant geographic distribution data in the whole or partial earth surface (including the atmosphere) space under the support of a computer hard and software system, and can clearly mark the geographic position, the altitude, the distance relation with a power grid for networking and other information of each alternative address in the micro site selection process under a geographic information system, but the information of earthquakes, typhoon historical occurrence conditions or administrative boundaries, natural protection areas and the like relevant to the micro site selection is not reflected.
The information about the micro-positioning has determined position and geographic information, and the position and the geographic information are the core and the foundation of the GIS. A simple longitude and latitude coordinate is only recognized and understood by a user after being placed in specific geographic information, representing a certain place, mark and direction. After the user acquires the location information through the related technology, the user needs to know the geographic environment and inquire and analyze the environment information, so that information support and service are provided for the user activities.
