Title:
DIRECT-CURRENT POWER SUPPLY AND DISTRIBUTION CONTROL METHOD AND SYSTEM AND DIRECT-CURRENT MICRO DATA CENTER
Document Type and Number:
WIPO Patent Application WO/2022/012427
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a direct-current power supply and distribution control method and system and a direct-current micro data center. The direct-current power supply and distribution control method comprises: controlling an online power generation unit and a direct-current power grid end to provide direct current for a load by means of a bus output side; monitoring the real-time voltage and real-time current of the bus output side; determining whether the real-time voltage is smaller than a preset protection voltage; if yes, controlling the bus output side to output a preset protection current; and if no, controlling the bus output side to output the preset protection voltage. The present disclosure reduces UPS configuration in traditional alternate current power supply and distribution, reduces energy consumption, and improves the operation stability of the power supply and distribution system and the operation safety of the direct-current micro data center.
