FZTYP7575LAF260 is a kind of intelligent three-phase high-voltage reactive power automatic compensation controller. It has the characteristics of high accuracy, fast response speed and strong anti-short circuit capacity. It is widely used in reactive power compensation of high voltage lines, distribution system, power plants and other occasions. The following article will focus on the application fields and working principle of FZTYP7575LAF260.

The application fields of FZTYP7575LAF260 are mainly used in all kinds of power networks with high voltage, and can be classified into four categories: electric power plants, high voltage substations, transmission networks and distribution networks. In electric power plants, it can be used for high voltage line reactive power automatic compensation to reduce the reactive power that is caused by the capacitance of the transmission line and the load of the electric power plants. In high voltage substations, it is used for reactive power compensation of some fault short circuits that might lead to long period tripping, overvoltage or even equipment damage. In transmission networks, it is used for reactive power compensation of high voltage lines to reduce harmonics and improve line utilization rate. In distribution networks, it can be used for reactive power compensation near the load end, so as to reduce voltage fluctuations and improve power factor of users.

The working principle of FZTYP7575LAF260 is mainly based on the function of power factor equation Y-Δ transformation. It uses the principle of closed-loop feedback control, and sets up the parameters such as power factor, volt-amperes, active power and reactive power in the control loop, and then captures the corresponding values by the detection device. Depending on the set parameters, it will tell the power electronics module to take corresponding control actions. It can adjust the command signals of the capacitor in a timely manner, so as to timely adjust the capacitance of the power factor compensation device, and realize the automatic reactive power compensation. The whole process is fully automated, and according to the set parameters, the required reactive power can be automatically compensated.

In summary, FZTYP7575Laf260 is an intelligent three-phase high-voltage reactive power automatic compensation controller with high accuracy, fast response speed and strong anti-short circuit capacity. It is widely used in the reactive power compensation of electric power plants, high voltage substations, transmission networks and distribution networks. Its working principle is mainly based on the power factor equation Y-Δ transform, and it can use closed-loop feedback control to adjust the command signals of the capacitor referred to real-time values, and realize automatic reactive power compensation.
