Research On Construction Of Large Scale Industry Enterprise Smart Grid

With the Development of Economics and Society, People's activities has impacted to the environment of the Earth, caused energy shortage, Environment pollution, climate change creating Global major problems. In this situation, low-carbon (green economy) economy development is becoming the World trend, in the parallel of new developed revolution of World Economics. Large Industrial Enterprise of China is one of the important and basic domains, besides it is also a large energy consumption field.Some countries have been trying to solve the problem, doing the research about Power Grid model, improving Power grid operation, to meet the Development of low-carbon Economics. Nowadays and in the early future, many Experts and Scholars address that Smart grid is one forward step of developing future Power grid. Improving the efficiency of operating Power Grid to meet the low-carbon Economics is a critical choice. In practical operation, Smart Grid addresses that it is not a fixed Power grid, formulating an invariability of scheme. Industrial Enterprise needs to rely on itself target and requirement solution of key problems to adapt with the present. In the process of designing Smart Grid, Industrial Enterprise should take the advantage and critical techniques of Smart Grid to carry out the most effective adjusting, by reason that Smart Grid is the developed creation contributing for the better environment condition.For large scale Industrial Enterprise, the development of Smart Grid naturally comes out with the revolution and creation for developing the Chinese Industrial Enterprise. My thesis is based on the present condition of Industrial Enterprise, and trying to construct the Smart Grid model for large scale Industrial Enterprise, the contain includes:research on construction of Smart Grid for Large scale Industrial Enterprise; Key technology and equipments for Smart Grid Industrial Enterprise; Energy management System of Smart Grid Industrial Enterprise; Deploying the storage power station in Smart Grid; new energy and renewable energy resources should join Smart Grid, besides analyzing the operating wind energy system in case of fault, a fuzzy control strategy to regulate the power of converters on the network side is proposed based on the characteristics of directly driven wind turbine with permanent magnet synchronous generator. The output reactive current of the converter is derived by the fuzzy control strategy to provide suitable reactive power to maintain the desired voltage after voltage sag.Research objective is realization energy saving and emission reduction, reducing loss for large scale industry enterprises, improving the electricity transformation, increasing the performance of reinforcement energy, the performance of using electrical energy; guarantee the reliability of power supply and production safety; friendly environment and contribution the new innovation for Industrial Enterprise.
