【摘要】：随着国家对风力发电的大力支持,近几年风力发电在我国发展迅速,装机容量逐年大幅度提升,但现阶段我国电网结构导致电网对电能的吸纳能力有限,而风能的大小又是不可控的,故电网对风电的电压、无功调节能力提出了更高的要求。为了满足电网对各系统子站的实时调度要求、提高值班人员的工作效率,着手开发风力发电适用的自动电压控制系统。本系统从本人工作单位的实际需求出发,采用实验研究、数值分析的方法对风电场自动电压控制系统进行需求分析、系统设计与实现、系统测试。通过理论结合实际的方法研究有别于传统电压控制系统、具有风力发电特色的自动电压控制系统。本文所设计系统采用B/S模式、使用SQLSERVER2003以及C#语言编制,通过数值分析、逻辑循环、逻辑判断来实现风电场的自动电压控制。通过学习和研究传统自动电压控制系统的运行原理,再结合本单位已经投运风电场的实际特点和风电场所在地的气候特点,重点运用数值分析的方法来开发具有风电适应性的自动电压控制系统。通过历史运行数据的录入,大量的通过表单数据来积累系统的学习经验,以此为基础,结合风电场所在地的数值天气预报,预测、分析、调节风电场的电压水平,以满足系统需求。
[Abstract]:With the great support of the country to wind power generation, wind power generation has developed rapidly in China in recent years, and the installed capacity has been greatly increased year by year. But at present, the power grid structure of our country leads to the limited capacity of the power grid to absorb electricity. However, the wind energy is not controllable, so the power grid put forward higher requirements for wind power voltage, reactive power regulation ability. In order to meet the real-time dispatching requirements of the system sub-stations, improve the working efficiency of the personnel on duty. Start to develop the automatic voltage control system for wind power generation. This system starts from the actual needs of my work unit, and adopts the experimental research. The method of numerical analysis is used to analyze the demand of automatic voltage control system of wind farm, design and implement the system, test the system, and study the method of combining theory with practice, which is different from the traditional voltage control system. Automatic voltage control system with the characteristics of wind power generation. The system designed in this paper uses B / S mode, SQLSERVER2003 and C # language programming, through numerical analysis, logical cycle. Logic judgment is used to realize the automatic voltage control of wind farm. By studying and studying the operation principle of the traditional automatic voltage control system. Combined with the unit has been put into operation of the actual characteristics of wind farms and the climate characteristics of the site of the wind farm. Focus on the use of numerical analysis method to develop an automatic voltage control system with wind power adaptability. Through the input of historical operation data, a large number of form data to accumulate system learning experience, based on this. Combined with the numerical weather forecast, prediction, analysis and regulation of the wind farm voltage level to meet the system requirements.
