| Due to the Inner Mongolia region’s rapid economic development, Inner Mongolia power grid electricity load has become increasingly complicated and diversified, more and more of linear resistance, impact, unbalanced load and rich harmonics of electrical devices connected to the electricity grid, the load factors will affect the Inner Mongolia utility grid in different degrees of power quality indicators. On the other hand, the traditional power quality monitoring means cannot adapt to rapid changes such as wind power, the electric iron load monitoring requirements, lead to Inner Mongolia electric power company utility grid power quality problem increasingly prominent. And now is a great variety of Inner Mongolia power quality online monitoring device, the good and bad are intermingled, incompatible with each other, need to study the corresponding technology, to strengthen the unity of the power quality data integration processing, to regulate the grid power quality online monitoring system of construction and the needs of the development of power grid.Intelligent power quality monitor based on the above situation, the Inner Mongolia it is particularly important to research and development and construction of the platform, the platform with practical, advanced, reliability, compatibility and scalability for the principle, research and development and built a set of standard, open platform for the power quality monitoring and management application system, selection of monitoring covers electric iron, wind power, photovoltaic, energy-consuming four types of load, including electric institute master station system, ordos wulanchabu 2 is the station system power supply bureau, power supply bureau and 11 substations of 35 pilot power quality monitoring system, monitoring data by monitoring terminal uploaded to the child, the child stood uploaded to host, sub station, master station also has the function of monitoring analysis, statistical report form. And the rapid changes in the load effect on the measurement, digital substation power quality monitoring is studied. Built for power quality monitoring and control system of the effective means, to strengthen the power quality data integration method provides a unified processing, power quality monitoring technology for the next step development laid a solid foundation. The platform built for the next step to carry out a comprehensive power quality monitoring laid the foundation, through the analysis of monitoring data we found that the current power grid power quality influence is still very serious, the completion of the power quality monitoring system for power quality problems found, governance provides technical strength. Provides direction for further popularization and application. |
