Research On The Complex System Of Power Plant Management Based On Information Network Integrated Analysis

With the increasing attention of environmental protection, energy saving of electric power industry also requires to be managed strictly, while seventy percent of China's power generation is based on coal-fired thermal, and fuel prices are changing frequently in recent years, which is significantly directly increasing the operating costs of the power plant. It brings great difficulties to the operation of thermal power plants. In addition, due to our national policy is to support renewable energy development, it also give pressure to the thermal power plant operation. With the development of knowledge economy and information networks, the power generation side's competition will face the challenges of implementation of energy efficient scheduling, new environmental protection standards and the electricity bidding. Nowadays, thermal power management can not effectively solve the resulting problems, the reason is short of energy-saving scheduling optimization model, short-term and long-term load forecasting model analysis and the evaluation management based on new environmental protection standards, so this paper proposes an information networks integrated analysis of the thermal power management, whose purpose is trying to solve these new problems in the thermal power, it will contribute to enhance the competitiveness of the thermal power plant under the new situation.In this context, the paper stands the perspective of an integrated information network, and presenting the themal power companies should consider how to manage a variety of resources, how to optimize business processes and so on. Through this study, a series of ideas and methods of network integration are present. It will give help for improving the management of thermal power business. The major work of this paper is as follows:(1) Base on the description of the development history of themal power management, the condition of thermal power management system and the optimization theories, the methodes and concepts of information network integration analysis are given, and defined its intension, function and feature. Based on these, it form the information network integrated analysis theory.(2) Analyze the impact factors for complex system of the thermal power management, including external environmental analysis which includes coal price fluctuations, energy saving requirement and the local water resources and so on. In the other side, the internal environmental analyses are fouce on the enterprise management itself.(3) Build thermal power complex management systems based on the information network integrated analysis theory, which union the company's fuel management, operation management, reliability management, maintenance mode, operation management, materials management and so on. The system is dynamic and integrated in order to achieve the transfer the information in related department at the same time to making real-time decision.(4) The database, model database and knowledge database of thermal power management are built by information network integrated analysis theory. Data mining technology is used to extract the pattern of the information changing in order to form the pretreatment information. Then the corresponding model will give the prediction, evaluation or decision information. At last, the knowledge database is used to modify or improved the results further. For example, in model database, a variance-covariance forecasting model is built to forecast long term load, which is useful of providing a more reasonable comments and suggestions to thermal power management.5) The performance evaluation of thermal complex management system is studied based on information network integrated analysis theory. The shortage of the currently performance is analyzed at first, and an index system is built from financial, energy saving and knowledge innovation three aspects. At last, a combined model of using entropy and AHP method to determine the weight is present to solve the evaluation problem, and a case study is also given.(6) An operatiom mechanism analysis of the thermal power system operation management is given, which is from enterprise management mechanism, power generation equipment operation maintenance mechanism and enterprise knowledge management system three aspects. The accordingly recommendations are also given. When the status of the device is needed to determine, a novel method FEAHP is used to evaluate the status, and a corresponding case analysis is also given.(7) A series protection mechanism is given from policy, technical support, human resources, knowledge innovation four aspects, and the corresponding recommendations are also given, which is help for the sustainable development of thermal power enterprise.
