【摘要】：電力市場的開展需要穩(wěn)定、可靠的運營環(huán)境。一個安全、優(yōu)質、經(jīng)濟運行的電力系統(tǒng)是進行電力、電量交易的重要條件。隨著國內各區(qū)域電網(wǎng)的峰谷差越來越大，電能質量和電網(wǎng)安全運行受到較大影響，，調度運行困難越來越大。自動發(fā)電控制是實現(xiàn)在線經(jīng)濟調度的必備條件，能優(yōu)化發(fā)電調度，降低發(fā)電費用。“兩個細則”是為了維護電力系統(tǒng)的安全穩(wěn)定運行，保證電能質量，是一種輔助管理措施。本文主要圍繞當前主流的600MW機組，提出基于負荷響應率的安全經(jīng)濟運行策略。 首先對國內外火電廠自動發(fā)電控制和經(jīng)濟性評價的相關研究進行了總結概述；其次，廣泛收集相關資料對火電廠運行優(yōu)化策略與經(jīng)濟性相關理論進行詳細解讀，根據(jù)河北南網(wǎng)某電廠機組基于負荷響應率的運行優(yōu)化工作實踐，研究分析了該類機組在河北南網(wǎng)實現(xiàn)運行效益最大化的影響因素和工作成果；再次，根據(jù)相關理論資料結合河北南網(wǎng)某電廠的實際情況，提出建立火電廠基于負荷響應率的運行優(yōu)化及經(jīng)濟性綜合評價，對該火電廠基于“兩個細則”市場環(huán)境運營情況進行綜合分析評價，以驗證并探究影響河北南網(wǎng)該類機組火電廠運行經(jīng)濟性的主要影響因素；最后從該電廠“兩個細則”的實施實證這些因素的影響程度，并提出從優(yōu)化機組負荷響應率出發(fā)找到機組既安全又經(jīng)濟的平衡點，從發(fā)電機組DCS系統(tǒng)性能、設備可靠性、企業(yè)管理等多方面對如何更好地提升發(fā)電機組負荷響應率提出了策略，并說明以設備可靠性管理為基礎的火電廠經(jīng)濟運行重要的現(xiàn)實意義，來實現(xiàn)火電廠全壽命期內綜合效益最大化與可持續(xù)發(fā)展。
[Abstract]:The development of power market needs a stable and reliable operating environment. A safe, high quality and economical power system is an important condition for power and electricity trading. With the increasing peak and valley difference of power grid in various regions of China, the power quality and safe operation of power grid are greatly affected, and the dispatching operation is becoming more and more difficult. Automatic power generation control is a necessary condition to realize online economic dispatching, which can optimize power generation scheduling and reduce power generation cost. The two rules are an auxiliary management measure to maintain the safe and stable operation of the power system and ensure the power quality. This paper mainly focuses on the current mainstream 600MW units, and puts forward a safe and economic operation strategy based on load response rate. Firstly, the related research on automatic power generation control and economic evaluation of thermal power plants at home and abroad is summarized and summarized. Secondly, the relevant data are widely collected to interpret the theory of operation optimization strategy and economy of thermal power plant in detail. According to the operation optimization practice of a power plant unit based on load response rate in Hebei South Power Network, The influencing factors and work results of maximizing the operation benefit of this kind of unit in Hebei South Power Network are studied and analyzed. Thirdly, according to the relevant theoretical data and the actual situation of a power plant in southern Hebei network, the operation optimization and economic comprehensive evaluation of thermal power plant based on load response rate are put forward. This paper makes a comprehensive analysis and evaluation of the operation of the thermal power plant based on the "two detailed rules" in order to verify and explore the main influencing factors on the operation economy of this kind of thermal power plant in Hebei Southern Power Network. Finally, the influence degree of these factors is proved by the implementation of the two detailed rules of the power plant, and the safe and economical balance point of the unit is found from optimizing the load response rate of the unit, from the performance of the DCS system of the generator set and the reliability of the equipment. The strategy of how to improve the load response rate of generator set is put forward in many aspects, such as enterprise management, and the important practical significance of economic operation of thermal power plant based on equipment reliability management is explained. To realize the maximization and sustainable development of comprehensive benefit in the whole life period of thermal power plant.
