【摘要】：隨著國家對風力發電的大力支持,近幾年風力發電在我國發展迅速,裝機容量逐年大幅度提升,但現階段我國電網結構導致電網對電能的吸納能力有限,而風能的大小又是不可控的,故電網對風電的電壓、無功調節能力提出了更高的要求。為了滿足電網對各系統子站的實時調度要求、提高值班人員的工作效率,著手開發風力發電適用的自動電壓控制系統。本系統從本人工作單位的實際需求出發,采用實驗研究、數值分析的方法對風電場自動電壓控制系統進行需求分析、系統設計與實現、系統測試。通過理論結合實際的方法研究有別于傳統電壓控制系統、具有風力發電特色的自動電壓控制系統。本文所設計系統采用B/S模式、使用SQLSERVER2003以及C#語言編制,通過數值分析、邏輯循環、邏輯判斷來實現風電場的自動電壓控制。通過學習和研究傳統自動電壓控制系統的運行原理,再結合本單位已經投運風電場的實際特點和風電場所在地的氣候特點,重點運用數值分析的方法來開發具有風電適應性的自動電壓控制系統。通過歷史運行數據的錄入,大量的通過表單數據來積累系統的學習經驗,以此為基礎,結合風電場所在地的數值天氣預報,預測、分析、調節風電場的電壓水平,以滿足系統需求。
[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.
