Description
Technical field
The utility model relates to a kind of acquiring electric energy information terminal, especially relates to a kind of transformer station electric energy integrated information collecting device.
Background technology
The quality of power supply refers to cause the deviation of voltage, electric current or the frequency of consumer fault or cisco unity malfunction, and its index comprises variation, frequency shift (FS), three-phase imbalance, harmonic wave, flickering, voltage dip and phenomenon such as jump.In recent years along with rapid development of social economy, electric load increases swift and violent, increasingly sophisticatedization of power load and variation, increasing high-power non-linear, impact, unbalanced load insert electrical network in succession, and the power quality problem of utility network is on the rise; On the other hand, along with the application of exact instrument and complex electronic equipment, the user more and more requires the electric energy supply of high-quality and high reliability.Along with the user is more and more higher to the requirement of the quality of power supply to understanding and the subscriber equipment of power quality problem, a lot of users also more and more pay close attention to power quality problem.Power quality problem has great loss to socio-economic development, and therefore providing the quality of power supply that can satisfy the 21 century user's request is a key character of intelligent grid.
Current, State Grid Corporation of China has proposed thinking of development and target that intelligent grid is built, therefore, tightly center on the thinking of development of State Grid Corporation of China, it is significant to improve the electrical network quality of power supply, the monitoring of the quality of power supply, assessment, improvement have become the important component part that current State Grid Corporation of China builds intelligent grid, and wherein electric energy quality monitoring then is the basis of analysis and evaluation and improvement.Foundation by electrical network electric energy quality monitoring management system, for comprehensive assessment, energy-saving and emission-reduction and the customization electric power of electric energy commercial operation, electrical network provides technical data, ensured the electricity consumption standard reliably, strengthened the high efficiency of electrical network supervision and management, guaranteed that electric energy enterprise is market-oriented, the adaptation market competition provides powerful means, to make contributions for building intelligent grid for making up the quality power environment.
From in June, 2007 so far, the Shanghai Electric Power Co electric energy quality monitoring system is by the construction of first phase, second phase and Expo electric energy quality monitoring, now built up an electric energy quality monitoring center that comprises 296 electric energy quality monitoring points, cover each electric pressure of 380V to 500kV, complete electric energy quality monitoring management system with stable state and transient power quality index collection, analysis, storage and displaying, assessment and one, the Shanghai Power Network that is built into of this system is carried out the monitoring of the quality of power supply, management and improvement and Data Source is provided and has analyzed foundation.
Because the quality of power supply on-line monitoring equipment price of installing in the present Shanghai Power Network transformer station is too expensive and complexity is installed, so this type of power quality monitoring device also is nowhere near from required complete degree.
