Do you know microcomputer integrated protection device ?

The microcomputer integrated protection device is mainly used for the protection and measurement and control of power plants, substations and distribution stations.

Microcomputer protection device plays multiple roles in power system.

1. Electrical protection. The protection device protects the electrical equipment in the power system from overload, short circuit, grounding and other electrical faults. Once a fault is detected, it automatically realizes a fault disconnect, thus protecting the safe operation of electrical equipment.

2. Measure and monitor. The protection device has power quality monitoring, current, voltage, power, power Angle and other parameters real-time monitoring and data collection functions. It can measure various electrical variables on the spot, including voltage, current, power, etc., and can carry out a large number of data processing to achieve a full range of electrical equipment condition monitoring.

3. Control the application. The protection device enables a variety of control operations, such as remote control, fault diagnosis and automatic reclosing. It can also integrate harmonic filters and static compensation devices to improve the stability and efficiency of the power system.

4. Communication function. The protection device has the communication function, and can transmit the measurement data and protection information to the upper computer, which is convenient to realize the automation of the distribution network. It usually supports serial port and network port communication, which can improve the automation level and operation efficiency of the power system.

5. System status monitoring. The protection device can monitor various parameters of the power system in real time, such as voltage, current, frequency, phase, etc., to detect anomalies in time and improve system safety.

6. Detect and rectify faults. The protection device can detect the fault signal, determine the fault type and location, and automatically remove the fault part, reduce human intervention, and improve the reliability of the system.

To sum up, the protection device is an indispensable part of the power system, it integrates a variety of functions, including protection, monitoring, control and communication, can effectively protect the stable operation of the power system.

“Anhuang” microcomputer integrated protection device has formed its own business cluster, widely used in power dispatching and cloud, transmission and transformation automation, intelligent power distribution, new energy and energy storage, integrated energy and virtual power plants, industrial Internet and intelligent manufacturing and other power fields.
