The world's first flexible substation into business shipments

The world's first ac-dc power distribution network based on flexible substation, 26, in the village of alibaba data located in zhangbei county small 2 port into commercial operation. What is the future distribution network? It is given a prototype.

global energy Internet dean Qiu Yufeng said, this is first put forward by the Chinese concept of power electronic technology and realize the great practice of & other; History will remember this day & throughout; 。

he explains, flexible substation is effectively transform of different forms of voltage and current, and with flexible and controllable plug-and-play way acceptance and distribution of electricity. Its & other; Flexible & throughout; Mainly reflects in: access is flexible: power supply and load can be ac power dc power supply; Power regulation between different ports is smooth, continuous, all the way after a power failure, one power supply automatic bearing all the load, without any gap; Is the power supply and load on the electric connection, but the power quality problems ( Harmonics, reactive power, voltage sag) Are isolated, it is equivalent to a firewall, prevent the harmonic pollution into the user side of the grid side, and vice versa. And the adjustment of the traditional substation but can only choose one, exclusive, ac and dc it too; All problems will be passed each other between grid and users. Under the condition of the traditional substation, the user if the new energy as power supply, all the way because of the intermittent, inevitably experience frequent switching power supply, the power of the frequent short supply interruption; Flexible substation can be perfect to solve this problem.

its north power chairman ji Tian Bo introduction, Zhang Bei flexible substation and ac/dc power distribution network demonstration project to introduce zhangbei county DE sheng village, 2. 5 mw photovoltaic power generation for poverty alleviation, satisfy the alibaba data port of the green energy demand, more to ensure the high quality of power supply. According to preliminary estimates, photovoltaic power generation using dc booster, improve the efficiency of the photovoltaic system by about 2%; Data server USES the dc power supply, around 600000 yuan per 10000 servers can save investment, reduce data center energy consumption about 10% & ndash; 20%.
