Super capacitor module state early warning system and method

Abstract

The invention discloses a super capacitor module state early warning system and method. The system comprises a superior control module, a communication module and an equipment end, the plurality of equipment ends are connected with the superior control module through the communication module; the superior control module is used for collecting and displaying the state information of each equipment end in real time through the communication module, issuing a control instruction, and performing point-to-point control on equipment which sends out early warning; the equipment end is used for judging the state of a charge-discharge switch of the super-capacity module and recording the working times of the super-capacity module by collecting voltage and temperature information of the super-capacity module, and transmitting the information and the state quantity to the superior control module through the communication module; and the communication module is used for connecting each equipment end with the superior control module to realize information transmission. According to the scheme, on one hand, the state of each capacitor module can be comprehensively collected, and on the other hand, the service life of one or more modules can be pre-judged in advance, so that the modules are replaced in time to reduce fault shutdown under the condition of not influencing equipment operation.

Description

technical field [0001] The invention belongs to the technical field of capacitor energy storage, and in particular relates to a supercapacitor module state early warning system and method. Background technique [0002] As an energy storage element, supercapacitors are widely used in energy recovery of devices in wind power, photovoltaics, rail transit and energy industries. In the application process, the number of configurations of supercapacitor modules is large and the distribution is wide. The real-time monitoring of its operating status and the prediction of the life of each capacitor module will become the primary tasks that affect the safety and efficient operation of supercapacitor modules. Overvoltage and overtemperature during the operation of the supercapacitor module will directly damage the supercapacitor, thereby affecting the safe and effective operation of the entire system. In the current application, the voltage and temperature information of the supercapa...

AI Technical Summary

Problems solved by technology

[0004] 1. Whether the supercapacitor module is faulty can only be known after the system sends out a fault alarm. There is no early warning function, poor real-time performance and potential safety hazards;

[0005] 2. In the case of a wide distribution of application sites and a large number of capacitor modules, capacitor modules with shortened service life cannot be found in time and located in time

[0006] The above problems have problems such as lag in reflection, delay in renovation and upgrading work, and impact on normal work continuity (production efficiency), etc.
