Abstract

The invention discloses an intelligent power capacitor with integration of real-time communication and data uploading. The intelligent power capacitor is characterized in that an RS-485 transceiver is embedded in the internal part of the intelligent power capacitor. One end of the RS-485 transceiver is connected with the master control MCU on the intelligent capacitor, and the other end of the RS-485 transceiver is connected with an RS-485 interface connected at the port of the intelligent power capacitor. The RS-485 interface is connected with an RS-232-to-RS-485 industrial control converter which is connected with a PC. The PC is connected with the master control MCU of the intelligent power capacitor via serial port debugging software. A serial port data communication mode based on an RS-485 communication protocol is adopted, and the intelligent power capacitor is connected with the PC via the RS-232-to-RS-485 industrial control converter so that real-time communication of the PC and the intelligent power capacitor can be realized, and the internal data of the intelligent power capacitor can be uploaded to the PC.

Description

technical field [0001] The invention belongs to the technical field of smart grid electronic communication, and relates to an intelligent power capacitor integrating real-time communication and data uploading. Background technique [0002] In the current low-voltage power system, the reactive power compensation scheme uses a single smart power capacitor for local compensation and multiple smart power capacitors for network use, but this compensation scheme has the following problems: 1. The smart power capacitor has signal acquisition and data processing function, and can detect the reactive power of the power grid in real time. Engineers and technicians can analyze the power grid working conditions and power quality based on these data, and adjust the compensation plan in time. However, the existing smart power capacitors cannot achieve real-time man-machine communication and data Uploading, engineers and technicians can only monitor the power grid and analyze the power qua...
