  2. In the deregulated power market ， the power grid operator is facing many uncertainty and risks risk concept ， risk analysis approach and risk management are introduced in chapter ii ， the maj or risks of grid operators is analyzed and evaluated in details based on the real situation and data of yueyang city, hunan province ， the economic risk resulting from the uncertainty of load prediction of whole system ， generation capacity and parallel quantity of the large enterprises self - owned power plant are analyzed meanwhile ， the increase of large enterprises self - owned power plant may cause economic and security risks considering different risk ， the qualitmive and quantitative approaches are respectively adopted the direct and indirect congestion risks are evaluated based on probabilistic theory and decision theory the retail pricing and trade modes are major areas embracing risks as well chapter iii divides the risks in internal and external ones based on the characteristics of risk and put forward the layered risk management approach

    詳細分析和論述了電網經營企業面臨的各種風險。基於湖南省岳陽地區電力市場的實際情況和多年歷史數據，採用定性分析和定量計算的手段具體分析了負荷、自備電廠發電量和上網電量預測不確定性以及自備電廠的大量增加給電網企業帶來的經濟性風險和安全性風險。無論是長期還是短期，阻塞不僅會對電網造成直接風險，還可能造成間接風險。
  3. The research achievements are as followed : studying the shortages and the improved methods of gm ( 1, 1 ) grey prediction model, considering the characteristic of the transformer chromatographic data, bring forward the method for converting a series of data which are sampled in different interval into a series of data in the same interval. the weakening operator is applied to reconstruct the transformer chromatographic data for attenuating or eliminating the influence of randomicity. the improved prediction model for power transformer interior fault is constructeded

    主要取得了以下研究成果：通過對gm （ 1 ， 1 ）灰色預測模型的缺陷及其改進方法的深入研究，針對變壓器色譜數據序列的特有規律，提出了原始非等間距色譜數據序列的等間距處理方法，運用弱化運算元改造原始序列，淡化或消除原始色譜數據序列由於受各種隨機因素影響所具有的隨機性，給出了適用范圍更廣的變壓器內部故障改進灰色預測模型的建模方法。
  4. The comparison of three models ( single variable time series model 、 multivariable time series model and gray prediction model ) shows that the multivariable time series model ' s prediction precision is the highest. it indicates that using recurrent composed bp networks can exactly predict the boiler fault in order to prevent the fault, and help operator of power plant to adjust the parameters in a permitting range

    通過基於遞推合成bp網路的單、多變量時間序列模型與灰色預測模型的預測精度分析計算表明，應用基於遞推合成bp網路的多變量時間序列模型能較準確的預測鍋爐故障，指導運行人員對機組進行即時調整，使預期的參數在允許范圍內，以避免故障的發生。
  5. This method firstly divides the initial data array into two groups properly and carrys on grey modeling to two groups separately ; secondly utilizing the moving operator, gets the prediction value of two data arrays with grey model separately ; lastly, adopting proper datum merge way, makes two group prediction data merge together and gets final initial data prediction value

    該方法是，首先將原始數據序列適當地分成兩組數據序列，並且對兩組數據序列分別進行灰色建模；然後利用平易運算元，分別用灰色模型求出兩數據序列的預測值；最後，採用適當的數據融合辦法，將兩組預測數據進行融合得到最終的原始數據序列的預測值。
