Intelligent transmission and transformation solution

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.

Intelligent GIS

Intelligent GIS (SF6 gas-insulated metal-enclosed switchgear) has excellent breaking performance, and adopts three-station isolated grounding switch and three-pole common box design, which is compact in structure. GIS has primary online monitoring and secondary intelligent control function; the intelligent terminal is installed locally, which can realize the operation of the switch and the disconnector in the interval and the signal feedback. The application of GOOSE technology saves the use of the whole station cable. Electronic transformers transmit such digital signals as current and voltage to the merging unit in FT3 format via fiber optic cable to realize measurement digitization.

Intelligent metal-armored switchgear

Intelligent metal armored switchgear adopts advanced signal monitoring and micro-processing technology to realize complete status monitoring, status indication, video image, integrated alarm, auxiliary control, auxiliary management and diagnosis of external communication of intelligent switchgear, and complies with IEC61850 Communication Protocol.

The intelligent grounding switch and the electric chassis are interlocked with each other, and they also have functions such as manual priority and remote operation.

Intelligent vacuum circuit breaker:

Perfect mechanical properties online monitoring

Current waveform monitoring of opening and closing coil and energy storage motor

Video image of the primary contact of the circuit breaker in entering and exit process

Online detection for the temperature of the main contact part of circuit breaker

Overall state monitoring, diagnosis and alarm of the circuit breaker mechanism

A variety of external communication methods and data storage can be accessed at any time

Electrical operation of the circuit breaker from the working position to the test position can be realized by background software, a hand-held terminal or a local intelligent device

Switchgear states online monitoring and fault diagnosis system:

Online real-time monitoring and alarm of temperature rise (node, environment) states

On-line detection and analysis of mechanical properties of operating mechanisms

Record (1 min before and 2 min after fault)

Online monitoring and alarm in insulation state

Power quality monitoring

Intelligent metal-armored switchgear

Intelligent low-voltage power distribution equipment is intelligent, communicable and networked by transforming from low-voltage electrical components to complete power distribution equipment.

High-configuration power distribution equipment:

Since digital instruments, fire detectors, frequency conversion, soft start, the controller of frame circuit breaker and some molded case circuit breakers have communication and control functions, these functional interfaces can be connected to the field bus or connected to DCS Ethernet through adapters, then the operator can control the power distribution equipment in the field in the monitoring room, and intuitively master the site conditions and real-time parameters of equipment operation.

Low-configuration power distribution equipment:

Since the switch components do not have the function of communication, our company can collect and upload the parameters and status of the equipment and issue some control commands through digital collectors, sensors, such as PLC installation.

The application of intelligent technology enables the intelligent and centralized control of the power distribution cabinet to achieve the “four remote” functions of remote control, remote metering, remote communication and remote adjustment. The development of intelligent and centralized control of power distribution cabinets has liberated a large amount of labor, saved a lot of materials, and provided the possibility for us to control the distribution equipment at dangerous special occasions in a more reliable manner.

Distribution network automation products

The distribution network automation series products can meet the needs of integrated regulation and control for distribution network, realize unified centralized management of distribution network dispatching, monitoring and control, and provide various FA implementation modes to meet the automation requirements of various field conditions. At the same time, it provides a comprehensive solution including intelligent distribution network automation master station software, intelligent distribution network automation terminal products, intelligent distributed FA system, intelligent switch controller series products, which can adapt to the distribution network system for monitoring, self-healing and management, analysis and decision support functions.
