Intelligent transmission and transformation solution

Qingdao Yihe Electric Group is specialized in intelligent products and services and providing customers with intelligent power transmission and transformation solutions. The Company has a new generation of distribution network feeder automation products, which continuously integrates IT technology and adopts distributed network protection technology; the product, relying on high-speed optical network communication, uses the quick decision made by intelligent terminals (DRTU) and can realize fault positioning, fault isolation and power restoration of feeder at the field interval layer, so as to further reduce the range and time of power outages.

The implementation of Yihe intelligent power transmission and transformation solution can effectively improve the automation degree and management level of the distribution network, and improve the stability and economy of power supply. Meanwhile, it provides users with advanced application functions such as power flow calculation, power outage management, load forecasting, simulation analysis, and economic operation, providing system access, metering management, and Internet query functions for distributed new energy; it renders technical support and decision basis for the comprehensive management and development plan of distribution network, which provides a strong guarantee for the rapid development of the social economy.
