Description

Uninterruptible Power Supply Control System with Capacitor}

The present invention relates to an uninterruptible power supply control system, and in particular, an uninterruptible power supply having a capacitor capable of supplying uninterruptible power to the load at all times as well as stable electrical energy storage by self-diagnosis function by using a capacitor (condenser) instead of the existing secondary battery. It relates to a power control system.

Due to the recent development of communication technology, the reach distance according to communication is remarkably shortened, and thus numerous repeaters are required between terminals. Communication facilities including repeaters must require an uninterruptible system in which a spare power system is configured in case of an emergency in case of a power outage. In the conventional preliminary power system using a secondary battery, the power failure of a repeater cannot be efficiently managed, so a new technology using a capacitor has been researched and developed.

Capacitor is a collective term for capacitors or capacitors for the purpose of energy storage, and refers to supercapacitors, ultracapacitors, and EDLC (Electric Double-Layer Capacitor) power capacitors. It is not a secondary battery that chemically stores electricity. Another concept refers to a cell for storing physical energy.

As the storage device of the capacitor uses the method of the secondary battery as it is, the charging time is very long and the setting of the charging voltage is limited, so the installation cost of the capacitor is high. In addition, the setting of the charging voltage of the capacitor (condenser) used in the past is a method that the reference voltage is set by the comparator and the indicator informs it above or below, and the reference voltage of the comparator is always temperature or element or As the diode performance deteriorates, the reference voltage may fluctuate. Particularly, as the reference voltage fluctuates, the life of the capacitor and the number of times of charging and discharging are shortened as the full charge voltage of the capacitor is higher, so that the lifespan is shortened and the capacitor or the circuit for charging is damaged. Therefore, the uninterruptible system of the charging method using the capacitor is required to protect the capacitor and increase the charging and discharging efficiency through the control of the final discharge voltage.

In the case of continuous discharge even below the discharge stop voltage, the lifespan of the capacitor may be shortened, or recharge may not be possible because the performance of the capacitor is not guaranteed with the ability to supply voltage to a simple load. Therefore, the capacitor must manage the end voltage and the full charge voltage according to the characteristics of each type. Therefore, the electric energy storage, charge voltage, and cell voltage in the circuit are always checked, and the full charge and discharge end voltages are maintained and operated at all times. Power control technology is required.

Currently, capacitors with large capacity from 3V 3000F are being produced or developed according to the development of material technology. Currently, only a small portion of the capacitors are used, but as the storage performance of the capacitors develops rapidly and the capacity is greatly increased, it can be used for electric vehicles, household equipment, and other firefighting equipment, lighting equipment, and communication facilities that require stable electricity. Therefore, various methods for replacing the conventional secondary battery have been studied.

In addition, in order to stably use and maintain the electric energy stored through the capacitor module as the power required by the load in real time, a remote circuit that monitors the power supply means input to the capacitor and selects the input power at all times and in case of power failure, and There is a need for an uninterruptible power supply control technology with communication and control functions that can check the state of the capacitor through a monitor.

When the unit 310 selects the emergency power (3W), the current voltage frequency control unit 700, which has received the signal from the central control panel 800, causes the current, voltage, and frequency to be supplied to the power required by the load connection unit 710. You can perform a monitoring function to convert.

Here, cracking down so that the selection unit 310 does not operate at all times (uninterrupted power) causes the remote monitoring unit 300 to reduce unnecessary power consumption at all times (uninterrupted power).

It performs a monitoring function to turn off.

Here, turning on/off the operation of the A/D converter 160 means that when the capacitor 610 is charged above the completion voltage, the capacitor 610 is charged every second (Sec) and every minute (Min). The charging voltage and charging current of the capacitor are optimally adjusted from the initial charging voltage of the capacitor 160 to the discharge end voltage by controlling the current charged in the battery and monitoring to stop the discharge of the capacitor 610 when the discharge end voltage arrives.

In addition, since voltage and current are also complex due to the complex configuration, the amount of power supplied to the load must be determined according to the cell or module, so the modules are made into an array in a series or parallel type according to the amount of power. Accordingly, the voltage and current of the cell or module are also different, so the increase in voltage and current must be determined according to the situation. To this end, an auto buck-boost converter configuration is required.

Therefore, in an embodiment of the present invention, a booster or a step-down auto buck booster that simultaneously adjusts the secondary voltage, current, and frequency of the capacitor 610 during power failure or uninterruption according to a signal from the remote monitoring unit 300. -boost) or an auto buck booster 630 that always transmits a constant voltage and current to the current voltage frequency control unit 700 through an auto converter to supply the optimum power required by the load connection unit 710 is configured. .
