Description
Technical Field
The invention relates to the technical field of power control, in particular to a redundant power supply device and a power supply method of a distributed power supply control system.
Background
In energy storage or power driving based on rechargeable batteries as energy sources, the batteries are generally connected in series to form a high-voltage system. Each of the series battery modules communicates with the host system through the cell management system. Based on the bottleneck effect, failure of one battery module generally means that the power output of the system where the entire battery module is located fails.
In the distributed control based on the cascading power electronics technology, each battery module is controlled independently, and the failure module can be bypassed without affecting the normal output of the system, so that redundancy of the strong current side is realized. However, the strong electric energy realizes redundant design, and does not mean that the weak electric energy part is naturally redundant. The control system of each battery module needs low-voltage power supply, and if the control system of a certain battery module is completely powered off, the low-voltage power supply system attached to the battery module is also completely powered off, which may cause loss of control capability.
The cascade system has a plurality of direct current power supplies, and outputs alternating current or direct current through cascade coordination control. Due to the dynamic connection specificity of the cascade system, isolation is realized between the sub-battery modules and the main battery module as well as the power supply part of the control system between the sub-battery modules. The power supply system is characterized in that a sub-module and a main module are adopted to supply power to the main module, and the main module supplies power to a sub-control system of each sub-battery module.
However, when the sub-module and the main power supply are adopted to supply power to the main power supply, the sub-control system for controlling the sub-battery module also loses the power supply capacity under the condition that the sub-battery module is powered off. When the main module is adopted to supply power to the sub-control systems of all the sub-battery modules, the main module needs to have a power supply source, and some applications can assume that the power is supplied by a UPS (uninterrupted power supply) or the power cannot be supplied by the UPS; for example, the entire cascade system itself is a UPS power source, and cannot be assumed to be supplied separately from the outside. In addition, the power supply circuit of a certain sub-battery module may fail, and even if the main control system still has a power supply, the sub-control system also fails, so that the whole power supply control system is stopped and related potential safety hazards are caused.
