Intelligent reactive compensation controller

An intelligent reactive compensation controller comprises a microcontroller module, a power supply module, a three-phase electric energy acquisition module, an RS485 communication interface, an Ethernet interface, a WiFi module, a liquid crystal screen display module, a multi-channel capacitor switching signal module, a multi-channel temperature acquisition module and a capacitor switching state and time module. The microcontroller module is respectively connected with the compensation capacitor and the multi-channel temperature acquisition module through a first RS485 communication interface, and the microcontroller module is connected with the capacitor switching state and time module through a second RS485 communication interface. Two network communication interfaces of WiFi communication and Ethernet communication are provided to access the Internet of Things or an exclusive network platform, and the two 485 communication interfaces can perform data acquisition or control and three-phase electric energy a
