Quality Optimization Technology Quality Optimization Technology In the process of building a smart grid, the power is divided into different levels, and then apply the method of assessment and judgment to master the basic situation of power supply and take measures to improve and perfect, to ensure the quality of power supply, to form a complete power supply system, Promote the smooth progress of power supply. In the process of smart grid construction, in order to promote the effective application of various technical measures and better meet the needs of actual work, a comprehensive analysis and evaluation of the economic, technical and quality of the grid should be carried out to determine the correct interface mode of power supply and power supply , Establish a sound evaluation system and improve power grid technology, improve management rules and regulations, promote power supply technology development and power quality optimization, and achieve better smart grid construction effect.
Energy Conversion Technology Traditional power grids are dominated by thermal power and hydropower, especially thermal power generation, causing serious pollution and damage to the surrounding environment. To improve and protect the environment, low-carbon energy is the future direction of energy development. Its utilization can effectively improve the surrounding ecological environment, reduce environmental pollution and achieve better comprehensive benefits. In order to make better use of low-carbon energy, it is necessary to adopt advanced energy conversion technologies to effectively change energy conversion methods, to better meet the needs of power generation, and to effectively improve energy efficiency. Currently more widely used is the solar power and wind power technology.
UHV transmission technologies include two types of UHV DC and UHV AC transmission technology, while UHV AC transmission technology refers to AC transmission technology with a supply voltage level above 1000 kV. In the UHV transmission process, the main types of technologies used include overvoltage control, application of insulating materials, simulation of high voltage stability, use of specialized equipment, and many more. The transmission technology has more significant advantages and characteristics in terms of power transmission, transmission distance, transmission efficiency and the like, and is of great significance to the operation of the entire power grid in a flexible and reliable manner.
Flexible transmission technology includes AC flexible and DC flexible two types of technology. AC flexibility mainly for high-power large-capacity container of electronic devices, such as SVC, CSR, these devices in the transmission process, can realize the reactive effect of compensation, but also effectively protect the power quality control to ensure smooth transmission. At the same time flexible transmission technology can better protect the power transmission, enabling rapid reactive power regulation, thus ensuring system stability. However, at present, the technology has not been vigorously promoted and applied, and is limited to the application to the construction of individual smart grids. In the future, we should further strengthen research and promote the improvement and popularization of the technology.
Smart sensing technology refers to the smart substation and related technology types, it is an important part of smart grid construction. In fact, the intelligent substation adopts a large number of technology types and takes the information automation technology as the guide, which can effectively monitor, regulate and protect the power transmission network so as to effectively guarantee the stable and reliable operation of the smart grid. In the future, we should intensify the research on the integration of related equipment, communications technologies and platforms, the automatic protection of device technology and related control technologies, and promote the continuous improvement of intelligent sensing technologies to achieve better application results.
Smart Devices and Smart Device Technology Smart grid construction can not be separated from smart device and smart device applications. This is an important task that can not be ignored. These technologies will be mainly covered in the power system distribution, power generation, transmission, substation and other sectors. At the same time, intelligent substation also widely uses these technologies, and each component is an independent node. Through the application of science and technology, it realizes functions such as networking, digitization, visualization and function integration of smart grid. In addition, the integrated design of transformers, circuit breakers, transformers, control, protection, design, measurement and metering devices should also be implemented to promote smart grid operation and development.
