DAIP AC and DC integrated power supply system
First, product overview
With AC and DC power integrated power supply equipment (hereinafter referred to as the integration of AC and DC power station) is used in AC power system (GZZ), DC power supply system (GZDW), power AC uninterruptible power supply (UPS) and power inverter power supply system (INV), communication with the direct streamization power supply (DC/DC) system the integration of design, production, monitoring, debugging, and implementation of station power integration, intelligence, network, security. The traditional station power supply design, different equipment from different suppliers, the communication protocol is generally not compatible, low degree of automation. Because there is no unified monitoring equipment for the whole station with power management, can not achieve the coefficient of data sharing, reliability, economy is poor. DAIP AC and DC integrated system has changed the existing problems of the traditional power supply, realize the information sharing of power supply station, fully meet the requirements of the current unmanned substation and digital substation station power supply.
Two, product features
1, can realize the unified management of power supply system, data sharing, through the integrated monitoring module and the background of integrated automatic system, can implement the system coordination linkage.
2, simplified station two times the design of power supply system, the entire station with the power system design standardization, the traditional complex of the two part of the use of intelligent modules, just enter the preparation of a good program.
3, operation and maintenance is convenient, save cost
4, system network, intelligent.
AC power supply, DC power supply, UPS power supply, DC/DC48V communication power supply, monitoring and remote control, communication and other data, through the integrated monitoring system access to fully automatic system, realize the power supply local and remote control. Run mode settings, event log view and a variety of parameter settings, information platform sharing, system support IE61850 protocol, to achieve network intelligent management

Five, the main functions and characteristics
1 system with a flexible power supply station
DC power supply and AC power supply, inverter power supply, communication power supply based on the scene to use different, any combination of a station power supply system
2 can realize the station power supply system management
AC power supply, inverter power supply, DC power supply, unified specification of communication power supply, data sharing, through the integrated monitoring module and the background of integrated automatic system, can realize the power supply system management, coordination linkage.
3 optimize the battery configuration, reduce the number of screen groups
Cancel communication battery and charging equipment, the use of DC/DC exchanger directly hung on the DC bus instead of UPS, can be eliminated using inverter DC bus instead of directly hung on, to avoid the communication power of UPS battery and battery maintenance is not fine, the damage can not be found in time to reduce the number of screen group colleagues.
4 dual monitoring module configuration, to ensure that the station is more safe and reliable power supply
The system is not only equipped with DAIP4.0-B or DAIP4.0-C integrated total monitor and total touch screen, local and remote can be achieved four remote, and each system has an independent monitoring module, can be in place separate operation.
5 to simplify the design of the two power station, the design of the entire station power supply.
Screen and screen through the LAN communication, external communication connection, for digital transmission.
The same model module can be interchangeable, easy maintenance and replacement. Colleagues shorten the supply cycle.
Convenient installation and service
Station power supply system in the two power supply control cabinet, DC power control cabinet, inverter power supply cabinet, UPS power supply cabinet, 48V communication power supply cabinet, battery cabinets are completed by a factory. Each subsystem communication protocol is compatible, the service only needs to find a factory to realize the integration of AC and DC turnkey project. Convenient operation and maintenance, saving cost.
6 effective suppression of the inverter power supply reverse current, unified lightning protection configuration
The anti - irrigation current of the inverter can effectively restrain the current of the DC current charging module. AC, DC into the line of unified lightning protection configuration. System network, intelligent
