The YH series integrated AC/DC uninterruptible power supply system for electric power is a comprehensive integration of AC/DC power supply system, DC power supply system, inverter power supply system, and communication power supply system. Through unified design, production, debugging, network communication, design optimization, system linkage, equipment intelligent file management and other methods, an integrated power monitoring system is achieved, which makes the network intelligence of the power system higher, the operation more convenient, the use safer, and the maintenance cost lower. It is an unmanned substation, an intelligent substation for network management, and realizes the full parameter online function of the system, as well as the opening and closing of circuit breakers, relay protection, automatic devices, signal devices and other AC/DC uninterruptible power supplies. It is related to the safe operation of the power grid, one of the core equipment for power generation and transmission, and a new generation. Power supply system equipment for electricity.

Scope of application

Suitable for AC/DC power supply locations required by power plants, substations, industrial and mining enterprises, and other power engineering projects.

System features

The system integrates advanced power conversion technology, pulse width modulation technology, digital control technology, electromagnetic compatibility technology, power drive technology, intelligent charging and discharging technology, redundant parallel technology, and network communication technology, and is a high-tech intelligent station power system;

Sharing battery packs reduces procurement costs, saves space, and improves economic efficiency;

● Integrated monitoring system, which can real-time view the power, switch status, file information of each subsystem, modify system parameters, operation mode, remote control switch and other functions, clear and easy to manage and maintain;

By communicating with the upper computer through the IEC61850 protocol, the comprehensive automation application management level of station power supply has been greatly improved;

Intelligent feeder monitoring, which can directly monitor the status of each feeder switch,

When the load is short circuited, do not shut down or interrupt the AC output,

There are isolation transformers between UPS power supply, inverter power supply, communication power supply and the original DC system, which will not cause system accidents due to grounding;

Limit the backflow ripple voltage on the DC bus to fully meet the safety standards of the power system;

The system configuration is flexible, and can be equipped with a single UPS or inverter cabinet (suitable for substations below 110KV), as well as two series hot backup or parallel redundancy (suitable for substations above 220KV or important power projects).
