【摘要】：未來我國用電負荷的穩(wěn)定、快速增長促進輸電網(wǎng)的快速發(fā)展。通過合理全面的輸電網(wǎng)工程項目規(guī)劃評價方法選擇科學合理經(jīng)濟的輸電網(wǎng)規(guī)劃方案,實現(xiàn)輸電網(wǎng)規(guī)劃質(zhì)量、速度和效益的統(tǒng)一,具有重要實際應(yīng)用價值。本研究通過研究輸電網(wǎng)工程項目規(guī)劃綜合評價的影響因素,根據(jù)系統(tǒng)理論、風險評價、成本—效益分析等理論建立輸電網(wǎng)規(guī)劃項目綜合評價方法對輸電網(wǎng)規(guī)劃項目進行科學合理、全方面的綜合評價分析。針對目前輸電網(wǎng)工程項目規(guī)劃評價中存在的問題,研究分析了大停電風險、短路電流、暫態(tài)穩(wěn)定、國民經(jīng)濟、能源資源、環(huán)境保護等因素對輸電網(wǎng)規(guī)劃評價指標體系的影響,分析總結(jié)國內(nèi)外在輸電網(wǎng)規(guī)劃項目評價指標體系及評價方法方面的已有成果,并確定了輸電網(wǎng)規(guī)劃項目綜合評價指標選取原則。在此基礎(chǔ)上,考慮輸電網(wǎng)運行的實際狀況,根據(jù)已有研究、實際情況及電力規(guī)劃專家的經(jīng)驗和意見,從安全性、經(jīng)濟性、適應(yīng)性三方面構(gòu)建輸電網(wǎng)工程項目規(guī)劃綜合評價指標體系,并提出各個子指標的量化計算方法。確定了輸電網(wǎng)工程項目規(guī)劃綜合評價方法的原則及思路,將熵權(quán)法、層次分析法獲得的指標權(quán)重采用自適應(yīng)粒子群優(yōu)化算法進行單目標尋優(yōu),并將所求優(yōu)化結(jié)果作為最終權(quán)重,并用模糊綜合評判對輸電網(wǎng)工程項目規(guī)劃方案作出綜合評價,由此構(gòu)建出輸電網(wǎng)工程項目規(guī)劃綜合評價方法。 在前面工作的基礎(chǔ)上,本文統(tǒng)籌考慮了輸電網(wǎng)工程項目規(guī)劃方案的安全性、經(jīng)濟性、適應(yīng)性等方面對輸電網(wǎng)工程項目規(guī)劃方案整體的影響,使用輸電網(wǎng)工程項目規(guī)劃綜合評價方法對某規(guī)劃特高壓輸電網(wǎng)工程項目規(guī)劃三個子規(guī)劃方案進行了研究。通過對不同規(guī)劃方案進行整體模糊綜合分析得到各個規(guī)劃方案評價分數(shù),根據(jù)不同的目的進行單方案評分和多方案比選。算例表明所建立的輸電網(wǎng)工程項目規(guī)劃綜合評價方法對選擇科學合理的輸電網(wǎng)工程項目規(guī)劃方案具有良好的指導(dǎo)作用,實際應(yīng)用中易于推廣使用。
[Abstract]:In the future, the power load of our country will be stable and the rapid growth will promote the rapid development of the transmission network. Through the rational and comprehensive project planning and evaluation method of transmission network project, the scientific, reasonable and economical transmission network planning scheme can be selected to realize the quality of transmission network planning. The unification of speed and benefit has important practical application value. This study studies the influence factors of comprehensive evaluation of transmission network project planning, according to the system theory, risk evaluation, Based on the theory of cost-benefit analysis, the comprehensive evaluation method of transmission network planning project is established. The comprehensive evaluation of transmission network planning project is carried out scientifically, rationally and in all aspects. In view of the problems existing in the project planning and evaluation of transmission network project at present, the comprehensive evaluation method of transmission network planning project is established. The risk of power outage, short-circuit current, transient stability, national economy, energy resources, environmental protection and other factors affecting the evaluation index system of transmission network planning are studied and analyzed. This paper analyzes and summarizes the existing achievements in the evaluation index system and evaluation method of transmission network planning project at home and abroad, and determines the selection principle of comprehensive evaluation index for transmission network planning project. On this basis, the actual situation of transmission network operation is considered. According to the existing research, actual situation and the experience and opinion of power planning experts, the comprehensive evaluation index system of transmission network project planning is constructed from three aspects: safety, economy and adaptability. The principle and train of thought of the comprehensive evaluation method of transmission network project planning are determined, and the entropy weight method is introduced. The index weight obtained by AHP adopts adaptive particle swarm optimization (APSO) algorithm for single objective optimization and takes the result of optimization as the final weight and makes a comprehensive evaluation of transmission network project planning scheme by fuzzy comprehensive evaluation. Therefore, a comprehensive evaluation method of transmission network project planning is constructed. On the basis of the previous work, this paper considers the effect of the safety, economy and adaptability of the transmission network project planning scheme on the transmission network project planning scheme as a whole. By using the comprehensive evaluation method of transmission network project planning, three sub-planning schemes of a planned UHV transmission network project planning are studied. Through the overall fuzzy comprehensive analysis of different planning schemes, each regulation is obtained. Plan evaluation score, According to different purposes, single project score and multi-scheme comparison and selection are carried out. The example shows that the comprehensive evaluation method of transmission network project planning has a good guiding effect on the selection of scientific and reasonable transmission network project planning scheme. It is easy to be popularized in practical application.
