To improve the power quality of the power grid, it is necessary to accurately monitor and analyze the power quality, measure the power quality level of the power grid, and analyze and judge the reasons for various power quality problems, providing a basic basis for improving power quality. The 10KV distribution network is a common type of distribution network in China, and as the distribution network for power users, the 10KV distribution network is widely distributed, with complex load changes in the grid structure. Due to its direct connection to the power supply load, its power quality is also easily affected.
From the perspective of this power grid system, improving the power quality level of the distribution network has a significant contribution to improving the overall power grid power quality level. From the perspective of the power supply role of the distribution network, effectively optimizing and improving the power quality of the 10KV distribution network directly determines the power quality of the upstream power grid and downstream users.
according toPower quality monitoringdeviceThe different monitoring methods can be roughly divided into three categories: specialized monitoring before equipment is connected to the network, regular or irregular maintenance of electricity in the power supply system, and online monitoring of electricity quality. Due to the influence of many factors on the quality of power supply, the overall power quality may be affected to a certain extent. For example, during the transmission process, there may be certain consumption or scheduling issues, which can also lead to issues with the quality of power supply.
In the process of transmission and allocation scheduling, the monitored data results are often relatively accurate and reliable. In most cases, it can meet the demand for power quality in the current intelligent distribution system.However, for the situation of electricity consumption, in order for the intelligent distribution network to better manage power quality data information, it is necessary to establish corresponding online dynamic monitoring systems, further monitoring the current electricity consumption data in real-time, and preparing for future power grid scheduling and energy consumption detection.
In the process of online monitoring of power quality, continuous collection, transportation, and recording can be achieved. It can better view relevant data in real-time and timely grasp the current voltage, power supply, frequency and other issues of the power grid system. If some characteristic parameters of power quality change, relevant personnel need to be able to analyze whether there are problems with power supply quality in a timely manner. If there are problems, corresponding measures can be taken in a timely manner, which can greatly improve the power quality of the power supply and distribution system.
