【摘要】：隨著電力系統(tǒng)的快速發(fā)展,使得電網(wǎng)需要對海量、異構(gòu)和多態(tài)的數(shù)據(jù)進(jìn)行分析與辨識。傳統(tǒng)的不良數(shù)據(jù)辨識方法辨識效率較低,且不能夠高效率利用已知的全部數(shù)據(jù)信息。為解決此問題,提出了一種基于負(fù)荷預(yù)測與關(guān)聯(lián)規(guī)則修正的不良數(shù)據(jù)辨識方法。根據(jù)數(shù)據(jù)量之間的內(nèi)在聯(lián)系,給出了一種三維矩陣的數(shù)據(jù)存儲方法。建立基于回歸分析法的預(yù)測模型與基于灰色關(guān)聯(lián)的相關(guān)性分析模型,分析節(jié)點(diǎn)注入功率與溫度之間的變化關(guān)系,并采用關(guān)聯(lián)規(guī)則與特殊斷面修正法對預(yù)測值進(jìn)行修正,進(jìn)而完成對注入功率的辨識。在此基礎(chǔ)上,再通過基爾霍夫定律與殘差辨識法完成對支路潮流數(shù)據(jù)的辨識工作。最后應(yīng)用實(shí)際系統(tǒng)的仿真算例證明了該方法能夠在克服殘差污染和殘差淹沒現(xiàn)象的前提下準(zhǔn)確辨識出全部的不良數(shù)據(jù)。
[Abstract]:With the rapid development of power system, the power network needs to analyze and identify the massive, heterogeneous and polymorphic data. In order to solve this problem, a bad data identification method based on load forecasting and association rule correction is proposed. In this paper, a data storage method of 3D matrix is presented, and a prediction model based on regression analysis and a correlation analysis model based on grey correlation are established to analyze the relationship between node injection power and temperature. The prediction value is corrected by association rules and special section correction method, and then the injection power identification is completed. On this basis. Through Kirchhoff's law and residual identification method, the identification of branch power flow data is completed. Finally, the simulation example of practical system is used to prove that this method can overcome residual pollution and residual submergence phenomenon. Identify all the bad data.
