MLS120 Series

Intelligent Power Distribution Management System

The MLS120 Series Intelligent Power Distribution Management System is a new-generation intelligent substation control and management platform. It consists of intelligent power sensors, smart gateways, station control units, and intelligent power distribution management software, with full-parameter data automatic modeling capabilities. Through internal configuration and mechanisms, it enables 3D digital modeling of switchgear, withdrawable units, circuit breakers, and power sensors. Using encrypted data transmission protocols, the system allows real-time visualization of electrical data, structural data, location data, and device interconnection relationships within the MLS120 software interface. The MLS120 Series enables real-time monitoring of electrical parameters, trend analysis, report management, event logging, and data sharing and backup. In addition, it offers asset management analysis and equipment capacity management functions to ensure the proper operation and utilization of power assets.


Product Features:


• The intelligent power distribution management system digitally models switchgear, drawers, circuit breakers, and power sensors in 3D through internal configuration and linking mechanisms. Power sensors use encrypted communication via smart gateways to digitally model full power data. Through the management software, customers can visually access data content, 3D structure, physical location, and device connection relationships.


• The current measuring transformer is highly integrated, minimizing wiring and facilitating installation and use. There are no internal connections, which saves space, improves maintenance efficiency, and reduces wiring-related errors.


• The intelligent power distribution management system adopts the standard MQTT IoT protocol via the smart gateway and provides encrypted JSON data streams. It supports digital twin technology and can be easily integrated with building automation systems, smart city management systems, and energy consumption management platforms.


• Intelligent sensors, smart gateways, station control units, and management software communicate via the TFP EasyLink protocol, enabling automatic 3D modeling of switchgear and automatic generation of associated device databases, single-line diagrams, and connection topology graphs through simple on-site configuration. This significantly reduces installation and debugging time and improves operational and maintenance efficiency.


• The MLS120 series intelligent measurement unit features factory-calibrated primary CTs, effectively resolving issues of measurement accuracy and CT phase angle deviation compensation.


• The EasyLink smart gateway is equipped with dual RS485 ports and dual Ethernet ports with a built-in switching chip. Gateways are connected in a cascading ring topology, which simplifies field communication setup compared to conventional star networks.
