Power quality monitoringdeviceIt mainly consists of on-site monitoring layer, communication transmission layer, and data management layer. The networking methods include three modes: network cable, fiber optic, and wireless.

On site monitoring layer: Install various types of electrical energy and power quality monitoring equipment on site, and require communication functions.

Communication transmission layer: In order to transmit the data collected by monitoring layer devices to the server, the devices responsible for data communication transmission mainly include communication management machines, serial servers, network switches, etc. The data acquisition terminal communicates with the monitoring layer device through a serial port, reads the data, conducts preliminary analysis and organization, saves the data in a local SD card, and then transmits the data to the wireless communication module. The wireless communication module adopts radio frequency technology to form a wireless local area network on site, collecting data organized by various data collection terminals and transmitting it to the backend server. Data can also be transmitted through network cables or optical fibers.

Data management layer: The process of storing, parsing, and applying collected data, including server setup and various software applications.

The standard power quality monitoring device has a CAD single line diagram to display the wiring situation of medium and low voltage distribution networks; The massive system has the function of multi screen switching and screen navigation; The decentralized distribution system has a spatial and geographical plane of the system's main screen. The main screen can directly display the operating status of each circuit, and has the function of coloring the circuit with power, non power, and faults. The main electrical parameters are directly displayed on the human-computer interaction interface and refreshed in real-time.

Through the power monitoring system, various electrical parameters and switch status of on-site equipment can be collected in real-time and timed, including three-phase voltage, current, power, power factor, frequency, harmonics, imbalance, current K coefficient, telephone waveform factor, voltage peak coefficient, electrical energy, temperature, switch position, equipment operation status, etc. The collected data can be directly displayed Or generate new intuitive data information through statistical calculations and display it (total system power, load value, upper and lower limits of power factor, etc.), and store important information in the database.
