Substation Power Equipment: Real - Time Monitoring and Precise Control via Remote I/O Control Cabinets


The remote I/O control cabinet in the substation plays a pivotal role in modern power monitoring systems. It is equipped to accurately collect a wide array of electrical parameters within the substation, including voltage, current, power, as well as environmental factors like temperature and humidity. These data are then promptly transmitted to the remote monitoring center or control system. For instance, sensors are utilized to gather the oil temperature data of the transformer in real - time. This enables the on - duty staff to have instant access to the equipment's operational status, ensuring early detection of potential issues and timely maintenance, thus enhancing the overall reliability and safety of the substation.

The control cabinet consists of a powerful 32-bit ARM processor main controller, paired with dual redundant power supplies, capable of stable operation under various harsh conditions. The I/O module has rich functions. The 64 channel analog input can accurately collect 4-20mA/0-10V signals, and the 32 channel digital I/O can quickly respond to 24VDC switch values, providing comprehensive and accurate data support for the system.



In terms of communication, the control panel has multiple configurations, with 4x RS-485 ports adapted to traditional equipment, 2x Ethernet (10/100Mbps) for high-speed data exchange, and optional fiber optic interfaces to meet special needs. It supports multiple communication protocols such as MODBUS RTU/TCP, and can easily integrate with SCADA/EMS systems to meet the real-time monitoring and control needs of smart grids, industrial substations, and other scenarios.

The remote I/O control cabinet of the substation collects data from on-site equipment, such as voltage, current, switch status, etc., and transmits it to the remote monitoring center. The remote monitoring center can analyze and process data, generate control instructions according to preset rules and strategies, and then send the control instructions back to the control cabinet through the communication network. The control cabinet executes the corresponding operations, realizing remote monitoring and control of substation equipment, and improving the intelligent level and management efficiency of substation operation.

Adopting modular design, each functional module operates independently

3 phase voltages:

3 - phase voltages consist of three alternating voltages with the same frequency but 120° phase differences. In a common system, the line - to - line voltage is around 380V and the line - to - neutral voltage is 220V. These voltages are used to power large - scale equipment in industry and commercial buildings, providing stable and efficient electrical supply.
