Hangzhou Zhonhen Electric Co., Ltd

Power Supply System Solution

Zhongheng ZHTS series AC-DC integrated power supply system solution is developed to resolve the problems such as low automation degree, complex system management and difficult information sharing of traditional power supply in transformer substation. The AC power supply, DC power supply, UPS/INV power supply, communication power supply and other power supply systems in the transformer substation are combined into an integrated power supply system through network communication, integrated monitoring, system linkage and other ways. The System solution realizes the safety of station power supply and intelligent network, solves the disadvantages of traditional separated power supply system, improves the intelligent level of transformer substation and the level of substation power supply management, improves the reliability and flexibility of power supply system, reduces the total project investment, and reduces the maintenance cost of the whole life cycle.

CTO reduced

Procurement and construction process simplified, total investment amount reduced, life cycle cost reduced.

Strong compatibility

The monitoring center unit is compatible with each part of the monitoring unit, and is accessed to the integrated automation system through unified interface and unified protocol.

Intelligence

Through the integrated monitor or remote management system, the information such as power consumption, switching value and events of each subsystem of the substation power can be viewed in real time, and the remote control can be utilized to realize the four-remote control function of the substation power supply.

Networking

The intelligent equipment of each power supply subsystem accesses the integrated monitor through the communication network, and the integrated monitor accesses the integrated automation/dispatching system through the A/B network port.

Integrated design

Uniform design style and same appearance will reduce repeated configuration, reduce the number of panels, save equipment cost and save floor area.

Facilitation

Battery type configuration is reduced, and the operating power battery, the UPS battery, communications power battery are integrated to a battery pack.
