ASDU-LSThe communication management machine product is used to complete the information exchange between intelligent electronic devices such as substation microcomputer protection, automatic devices, measurement and control, and the substation main computer system and power grid automation system, realizing the information exchange from various remote power stations to the upper host.stillIt can be used as a master control substation and front-end processor in a comprehensive automation system, forming the middle layer of the automation system. It can communicate with various systems such as the main station through computer communication upwards, and communicate with terminal devices within its jurisdiction downwards to complete the collection and forwarding of terminal device data. It can completely replace the functions of microcomputer substations or front-end processors.

Hardware function:

• Manage automatic device communication;

• Manage communication for various smart energy meters;

Manage intelligent auxiliary equipment in substations, such as DC power communication;

• Manage the communication of the substation main computer system;
