【摘要】：目前我國部分風電開發(fā)大省由于電網(wǎng)對風電的消納能力不足存在比較嚴重的棄風現(xiàn)象�？茖W地統(tǒng)計風電場棄風電量及其構(gòu)成,對于確定合理棄風的原則和條件,并制定相關考核機制和補償方案具有重要參考價值,同時對于電網(wǎng)節(jié)能調(diào)度、提高風能利用率、分析風電場的運行管理情況也具有重要意義。分析了現(xiàn)有棄風電量統(tǒng)計方法的原理及特點,提出了基于風電機組監(jiān)測數(shù)據(jù)的棄風電量計算方法及根據(jù)風電機組運行狀態(tài)對棄風電量分類統(tǒng)計的方法。該方法使用實測的風電機組運行狀態(tài)、風速、風向和功率數(shù)據(jù)作為計算棄風電量的基礎,不僅能夠更加準確地計算總棄風電量,還能夠分類統(tǒng)計不同原因造成的棄風電量。另外,采用內(nèi)蒙古電網(wǎng)風電場的實際算例驗證了該方法的有效性和適用性。
[Abstract]:At present, there is a serious phenomenon of wind abandonment in some major wind power development provinces due to the insufficient capacity of the power grid to absorb wind power. The scientific statistics of wind power output and its composition are of great reference value for determining the principles and conditions of reasonable wind abandonment, and for establishing relevant assessment mechanisms and compensation schemes, and for grid energy conservation and dispatching, and for improving the utilization of wind energy. It is also of great significance to analyze the operation and management of wind farm. This paper analyzes on the principle and characteristics of the existing statistical methods of abandoned wind power, and puts forward a method of calculating the quantity of abandoned wind power based on the monitoring data of wind turbine and classifying the quantity of abandoned wind power according to the operating state of wind turbine. The method uses the measured wind turbine operating state, wind speed, wind direction and power data as the basis for calculating the abandoned wind power. It can not only calculate the total abandoned wind power more accurately, but also classify and calculate the abandoned wind power volume caused by different reasons. In addition, the effectiveness and applicability of the method are verified by a practical example of wind farm in Inner Mongolia Power Grid.
