Description

Synchronous control system architecture to improve energy efficiency

The invention relates to the field of energy-saving control technology of multi-system serial connection, in particular, a hardware switch is not required, and the main system can communicate with the plurality of subsystems through the firmware to obtain battery information, and the remote synchronization is controlled multiple times. The system's synchronous control system architecture.

Today, with the continuous advancement of technology, energy demand has risen rapidly in recent years, and energy solutions such as nuclear energy, hydropower, solar energy, wind power and biomass energy have been widely discussed. However, the above-mentioned renewable energy sources are mostly related to the climatic environment, and the problem of unstable power supply has yet to be resolved. Therefore, the power storage system can not only help the power plant solve the problem of the stability of the renewable energy source. From power generation, transmission and distribution to the customer side, it can adjust the unbalanced power load system, stabilize the voltage, and the energy storage system that can solve the backup capacity, which will play a key supporting role in the development of renewable energy applications.

In the traditional energy storage system, multiple master-slave architecture systems are connected to the system as a complete energy storage system. When the single master-slave architecture system is damaged in this energy storage system, it can be directly manual. The hardware switch of the damaged master-slave architecture system is turned off, thereby disconnecting the damaged master-slave architecture system from the entire energy storage system, thereby preventing the entire energy storage system from being paralyzed. After the damaged master-slave architecture system is shut down, other normal master-slave architecture systems can still operate normally, so that the entire energy storage system can complete the energy storage work.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a conventional master-slave architecture system without communication function. The master-slave architecture system 800 includes a master system 802 and two power supply subsystems, a first power supply subsystem 804 and a second power supply subsystem 806, respectively. The main system 802 is connected to the first power supply subsystem 804 and the second power supply subsystem 806, respectively. The first power supply subsystem 804 has a first hardware switch 8042, the second power supply subsystem 806 has a second hardware switch 8062. Since the main system 802 of the master-slave architecture system 800 does not have a communication function between the first power supply subsystem 804 and the second power supply subsystem 806, the main system cannot determine the opening and closing of the system twice. When the first power supply subsystem 804 is damaged, the first power supply subsystem 104 can only be turned off by turning off the first hardware switch 8042 to maintain the normal operation of the entire master-slave architecture system 800. In this case, since there is no communication function between the main system 802 and the power supply subsystems, the power supply subsystem cannot be remotely controlled, and the state of the secondary system cannot be monitored immediately, and the disadvantage of using the hardware switch is that the system cannot enter. Power saving mode.

Furthermore, the main system 802 and the two power supply subsystems are connected in parallel. Since there is no communication function between the main system 802 and the two power supply subsystems, the main system 802 cannot immediately detect the voltage difference, and cannot supply the power supply subsystem. When it is turned off, there will be a dangerous situation with a voltage difference, that is, an excessive charge and discharge current occurs.

Please refer to FIG. 2, which is a schematic diagram of a conventional master-slave architecture system with remote control functions. The master-slave architecture system 900 includes a host system 902 and a first power supply subsystem 904 and a second power supply subsystem 906. The main system 902 is connected to the first power supply subsystem 904 and the second power supply subsystem 906, respectively. Main system 902 includes a hardware switch 9022. The hardware switch 9022 of the main system 902 can remotely transmit a control signal to the first power supply subsystem 904 and the second power supply subsystem 906. Although the main system 902 can remotely control the opening or closing of the first power supply subsystem 904 and the second power supply subsystem 906 by the switch 9022, the first power supply subsystem 904 and the second power supply subsystem 906 need to be in operation for a long time. The mode waits to receive the control signal transmitted by the main system 902 at any time, and therefore cannot enter the power saving mode.

In summary, the existing master-slave architecture system, especially in communication and real-time monitoring, has room for improvement, and it is urgent to improve the above shortcomings.

In view of the lack of the prior art, the present invention aims to provide a synchronous control system architecture that improves energy-saving efficiency.
