Technical field
本发明涉及发电系统技术领域， 特别涉及一种并网型风光联合发电系 统。 本发明还涉及一种并网型风光联合发电方法。 背景技术  The invention relates to the technical field of power generation systems, and in particular to a grid-connected wind and light combined power generation system. The invention also relates to a grid-connected wind-light combined power generation method. Background technique
随着世界范围内能源危机的爆发， 风力和太阳能等可再生能源得到越 来越广泛的应用， 从而带动了风力发电系统和太阳能发电系统的发展。  With the outbreak of the global energy crisis, renewable energy sources such as wind and solar energy have become more and more widely used, which has led to the development of wind power generation systems and solar power generation systems.
发电系统一般分为离网型系统和并网型系统。 离网型系统与电网不相 关联， 独立运行， 发电功率较小， 主要用于偏远地区、 海岛等电网不能辐 射到的地方供电使用， 应用范围较为有限。 并网型系统的发电机产生电能 后， 通过并网设备将电能并入电网， 并通过电网向大网用户供电。  Power generation systems are generally classified into off-grid systems and grid-connected systems. The off-grid system is not associated with the grid, operates independently, and has low power generation. It is mainly used for power supply in remote areas, islands and other places where the power grid cannot be radiated. The application range is limited. After the generator of the grid-connected system generates electric energy, it integrates the electric energy into the grid through the grid-connected equipment, and supplies power to the large-network users through the grid.
由于自然条件的限制， 单一利用风力发电系统或者利用太阳能的光伏 发电系统存在电力供应不足或者不平衡等缺点， 而两种发电系统共同使用 则能够在一定程度上克服上述缺点， 因此， 将风力发电与光伏发电技术相 结合的风光联合发电系统便应运而生了。  Due to the limitation of natural conditions, photovoltaic power generation systems that use wind power generation systems alone or use solar energy have shortcomings such as insufficient or unbalanced power supply, and the joint use of the two power generation systems can overcome the above disadvantages to some extent. A combined wind and solar power generation system combined with photovoltaic power generation technology came into being.
由于大型电网的用户量较大， 对电力供应的稳定性和安全性的要求较 高， 而风力资源和光照资源均具有间歇性、 波动性等特点， 使得上述风光 联合发电系统无法大规模地应用于并网型的发电系统中， 限制了风光联合 发电系统的应用范围。 即使将风光联合发电系统应用于并网型系统中， 由 于风力资源和光照资源具有间歇性、波动性等特点，会影响电网的稳定性， 降低电网的供电质量。  Due to the large number of users of large-scale power grids, the requirements for stability and safety of power supply are high, and the wind resources and lighting resources are characterized by intermittent and volatility, which makes the above-mentioned wind-light combined power generation system unable to be applied on a large scale. In the grid-connected power generation system, the application range of the wind-light combined power generation system is limited. Even if the wind-light combined power generation system is applied to the grid-connected system, the wind resource and the light resource have intermittent and volatility characteristics, which will affect the stability of the power grid and reduce the power quality of the power grid.
因此， 如何提高并网型风光联合发电系统的供电稳定性， 从而降低其 对电网稳定性的不良影响， 保证电网供电质量， 就成为本领域技术人员亟 须解决的问题。 发明内容 Therefore, how to improve the power supply stability of the grid-connected wind and solar power generation system, thereby reducing its adverse effect on the stability of the power grid and ensuring the power quality of the power grid, has become an urgent problem for those skilled in the art. Summary of the invention
本发明的目的是提供一种并网型风光联合发电系统， 其具有较高的供 电稳定性， 从而保证了电网的供电质量。  It is an object of the present invention to provide a grid-connected wind and solar power generation system that has high power supply stability, thereby ensuring power quality of the power grid.
