Modular data center system based on direct-current bus

Abstract

The invention discloses a modular data center system based on a direct-current bus. The system is characterized in that the system comprises a power input module, a DC / DC power conversion module, a power distribution module, and an EMS system, wherein the power supply input module is divided into photovoltaic input, alternating current input and storage battery input; three paths of power suppliesare uniformly converted into direct current through the energy storage converter PSC, and the direct current is input into the DC / DC power conversion module; the DC / DC power conversion module is subjected to DCDC conversion twice; and the power distribution module is used for distributing power to each DC load in the data center. The modular data center system is uniformly allocated by a superiorEMS, uses various modes such as an alternating current power supply, photovoltaic power generation and a storage battery as power supplies to form complementary input, and converges into a direct current bus for electric energy transmission; the direct current is transmitted to a server of a data center and each direct current load in the data center through direct current conversion and power distribution of each power module.

Description

technical field [0001] The invention relates to a DC bus-based modular data center system, which belongs to the technical field of power supply and distribution. Background technique [0002] The data center usually refers to the material carrier that realizes the centralized processing, storage, transmission, exchange and management of information through the function of computer clusters. The power supply technology is the transformation voltage and direct A technology for an electrical network system that distributes electrical energy to end users. Data center power supply technology is a power supply technology that converts each input power supply and outputs the DC power required by the server, and can realize uninterrupted power supply when the external input fails. [0003] Whether domestic or foreign, the traditional data center power supply technology is based on AC bus power supply. Due to the complexity of AC frequency and phase, the AC bus is not conducive to p...

Problems solved by technology

[0003] Whether it is domestic or foreign, the traditional data center power supply technology is mainly based on AC bus power supply. Due to the complexity of AC frequency and phase, the AC bus is not conducive to parallel power supply and electrical equipment, endangering system stability.

The traditional data center power supply technology has a single type of input power, generally only the mains input, and a separate rear battery is required, which brings inconvenience to system maintenance

The traditional data center power supply technology is dominated by AC UPS power supply technology, which has many single-point failures and is difficult to maintain. Generally, it is difficult to form a modular architecture for data centers that use AC uninterruptible power supplies. Due to the low load rate of AC UPS and low conversion efficiency Low, the huge energy consumption brought to the system is also incalculable

[0004] The current power supply technology and monitoring system on the market are not perfect, and the unstable operation of the computer room may easily cause data loss, and the loss cannot be estimated

The redundancy effect of its power distribution scheme is not good, the maintenance cost is high, and the problems of low reliability need to be solved urgently
