【摘要】：電力調(diào)度工作最核心的任務是要維系系統(tǒng)出力與負荷相平衡、保證電力系統(tǒng)安全穩(wěn)定的運行,因此發(fā)電計劃管理工作是電網(wǎng)安全調(diào)度非常重要的環(huán)節(jié)。隨著山西電網(wǎng)的飛速發(fā)展,特別是特高壓投運和新能源不斷接入,需要采用更為高效的協(xié)調(diào)運作機制和更為先進的技術(shù)支持手段來保證電網(wǎng)安全穩(wěn)定運行和連續(xù)供電。本文首先對山西電網(wǎng)調(diào)度計劃及安全校核系統(tǒng)中的日計劃系統(tǒng)的決策技術(shù)和模式制定進行了分析和研究,包括了日調(diào)度計劃、火電調(diào)度計劃、實時調(diào)度計劃、阻塞管理四個模塊并構(gòu)建了數(shù)學模型及其算法。其次,本文對山西電網(wǎng)調(diào)度計劃及安全校核系統(tǒng)的總體設計和組建方案進行了詳細論述。在系統(tǒng)安全方面嚴格遵循山西電網(wǎng)的規(guī)定,按照安全等級部署于安全二區(qū)中,對外部訪問進行了嚴格的數(shù)據(jù)過濾和權(quán)限控制。系統(tǒng)的硬件體系結(jié)構(gòu)由信息采集平臺、日前計劃子系統(tǒng)、實時調(diào)度計劃子系統(tǒng)、運行監(jiān)視、數(shù)據(jù)統(tǒng)計分析子系統(tǒng)等構(gòu)成。可以根據(jù)系統(tǒng)的要求建立遙測實時庫、計劃實時庫、趨勢實時庫等核心數(shù)據(jù)實時庫,同時系統(tǒng)還能夠處理各種運行信息的實時庫,負責整個應用系統(tǒng)的實時數(shù)據(jù)庫管理、實時數(shù)據(jù)處理、統(tǒng)計數(shù)據(jù)處理、報警處理、運算、數(shù)據(jù)服務請求處理,并提供雙機熱備功能。最后,本文將山西電網(wǎng)調(diào)度計劃及安全校核系統(tǒng)研究的各功能應用到山西電網(wǎng)調(diào)度運行實際中去,對各功能的應用做了全方位的結(jié)果分析與運行監(jiān)視,該系統(tǒng)立足于山西電網(wǎng)調(diào)度實際情況,發(fā)掘資源配置效率提升空間,從數(shù)學模型、物理實際及經(jīng)濟學角度剖析了日發(fā)電調(diào)度的協(xié)調(diào)配置機理,提出了相應的多目標優(yōu)化決策技術(shù),并搭建了先進的調(diào)度決策技術(shù)支持系統(tǒng),顯著提高了山西電網(wǎng)日發(fā)電調(diào)度決策的前瞻性和可執(zhí)行性。
[Abstract]:The core task of power dispatching is to maintain the balance of power and load, and to ensure the safe and stable operation of power system. With the rapid development of Shanxi power grid, especially the UHV operation and new energy access. More efficient coordinated operation mechanism and more advanced technical support are needed to ensure the safe and stable operation and continuous power supply of the power network. Firstly, the daily planning system of Shanxi power grid dispatching plan and safety check system is introduced in this paper. The decision-making technology and model of the system are analyzed and studied. Including daily scheduling plan, thermal power scheduling plan, real-time scheduling plan, blocking management four modules and build a mathematical model and algorithm. Secondly. In this paper, the overall design and construction scheme of Shanxi power grid dispatching plan and safety check system are discussed in detail. The system security strictly follows the regulations of Shanxi power network and is deployed in the second area of security according to the security level. The hardware architecture of the system is composed of information acquisition platform, pre-day planning subsystem, real-time scheduling planning subsystem, and operation monitoring. According to the requirements of the system, the real-time database of telemetry, the real-time database of plan, the real-time database of trend, and so on can be established. At the same time, the system can also deal with all kinds of real-time database of operation information. Responsible for the whole application system real-time database management, real-time data processing, statistical data processing, alarm processing, operation, data service request processing, and provide dual-computer hot standby function. In this paper, the functions of Shanxi power grid dispatching plan and security check system are applied to the actual operation of Shanxi power grid dispatching, and the results of the application of each function are analyzed and monitored in all directions. This system is based on the actual situation of Shanxi power grid dispatching, excavates the space to improve the efficiency of resource allocation, and analyzes the coordination allocation mechanism of daily generation dispatching from the point of view of mathematical model, physical reality and economics. The corresponding multi-objective optimization decision technology is put forward and the advanced dispatching decision support system is built, which improves the foresight and executability of the daily generation dispatch decision in Shanxi power grid.
