In this situation, low-carbon (green economy)cconomy devclopment is becoming the World trend, in the parallel of ncw developedrevolution of World Economics. Large Industrial Enterprise of China is one of theimportant and basic domains, besides it is also a large energy consumption fieldSome countries have been trying to solve the problem, doing the research aboutPower Grid model, improving Power grid operation, to meet the Development of lowcarbon Economics Nowadays and in the early future, many Experts and Scholars addressthat Smart grid is one forward step of developing future Power grid. Improving theefficiency of operating Power Grid to meet the low-carbon Economics is a critical choiceIn practical operation, Smart Grid addresses that it is not a fixed Power grid, formulating aninvariability of scheme. Industrial Enterprise needs to rely on itself target and requirementsolution of key problems to adapt with the present In the process of designing Smart gridndustrial Enterprise should take the advantage and critical techniques of Smart grid tocarry out the most effective adjusting by reason that Smart Grid is the developed creationcontributing for the better environment conditionFor large scale Industrial Enterprise, the development of smart Grid naturally comesout with the revolution and creation for developing the Chinese Industrial Enterprise. Mthesis is based on the present condition of Industrial Enterprise, and trying to construct theSmart Grid model for large scale Industrial Enterprise, the contain includes: research onconstruction of Smart Grid for Large scale Industrial Enterprise, Key technology andcquipments for Smart Grid Industrial Entcrprisc: Encrgy management Systcm of SmartGrid Industrial Enterprise, Deploying the storage power station in Smart Grid; new energyand renewable energy resources should join Smart Grid, besides analyzing the operatingwind energy system in case of fault, a fuzzy control strategy to regulate the power ofconverters on the network side is proposed based on the characteristics of directly driven华中科技大学博士学位论文wind turbine with permanent magnet synchronous generator. The output reactive current ofthe converter is derived by the fuzzy control strategy to provide suitable reactive power tomaintain the desired voltage after voltage sagResearch objective is realization energy saving and emission reduction, reducing lossfor large scale industry enterprises, improving the electricity transformation, increasing theperformance of reinforcement energy, the performance of using electrical energy; guaranteethe reliability of power supply and production safety; friendly environment andcontribution the new innovation for Industrial EnterpriseSmart Grid; Industry enterprise, Energy management system;Energy storage station; Wind power system华中科技大学博士学位论文目录摘要ABSTRACT绪论1.1研究背景·································*················································*········2智能电网研究现状与趋势1.3智能电网的概念及特征14中国大型工业企业的发展及当前形势1.5本文的主要工作及章节安排2大型工业企业智能电网构建框架2.1引言2,2大型工业企业智能电网构建框架研究2.3大型工业企业智能电网基础设备关键技术(15)24大型工业企业智能电网能量优化管理与决策支持系统.25本章小结(24)3大型工业企业智能电网能量管理系统框架研究3.1引言.·着非非·非非着非。非非非非·非非非非非·非非非。非·非非自非非自·非非非非··非,·非·申,··着非。非··非非非非非非非音。··非…25)3.2大型工业企业能量种类、特点及相互关系…·非·非非非着非·音·,非非非(26)33大型工业企业能量管理系统概述……(29)34系统关键模块和技术3.5本章小结·····:···············;················:·;················(38
