Apparatus and method for switching system power using lightning prediction information

The present invention relates to an apparatus and method for switching power of a system using lightning prediction information, and more particularly, analyzes brain discharge information and thundercloud development information to switch the main power of a load system to standby power before a brain discharge occurs. The present invention relates to an apparatus and method for switching power of a system using lightning prediction information for controlling recovery to main power according to monitoring results of brain discharge information and thundercloud development information after switching to standby power.

In general, the most common cause of thunder or lightning is a thundercloud. These thunderclouds are charged with electricity and generally consist of positively charged ice crystals at the top and negatively charged water droplets at the bottom.

These thunderclouds are formed through a cumulus phase with strong updrafts, a maturation phase with updrafts, gusts, thunderstorms, and showers, and a dissipation phase, in which downdrafts dominate and stabilize. It is likely to occur when elevated in the environment.

Lightning is a phenomenon in which the electric charge of a thundercloud is released to the ground through air insulation breakdown, and in this process, an electromagnetic field is generated and propagated in the atmosphere.

The technology that analyzes the location of lightning strikes can predict the activity and movement path of thunderclouds and the occurrence of lightning, so that observation of meteorological conditions at the time of launch of a spacecraft, safety measures in major buildings and power facilities on the ground, and activities at golf courses and playgrounds are possible. It is applied as a means of preventing damage caused by weather observation and lightning in various fields such as securing the safety of

It is estimated that about 1 million lightning strikes occur each year, and the damage caused by these lightning strikes and their scale are increasing day by day in the areas of land, sea, and air.

In particular, when a surge voltage due to lightning strikes the power equipment system, the insulation of the power equipment system is destroyed by a potential difference between the surge voltage and the system ground, and power is cut off, resulting in accidents and damage due to power outages.

Therefore, as a countermeasure to prevent damage caused by lightning in a power facility system, a technology for converting main power into standby power is being applied.

Korean Registered Patent Publication No. 10-2009856 (Title of Invention: Railway Equipment Power Supply Apparatus and Method) discloses a configuration for blocking surge voltage from being supplied to a rectifier.

However, in the prior art, when a fuse is blown due to a surge voltage being supplied to the first power supply line and emergency power is supplied through the emergency power supply unit, it takes a long time to restore the main power again because the first power supply line is damaged. There is a problem with this.

In addition, in the prior art, if the surge voltage is blocked from being supplied, it can be restored to its original state through manual recovery by a manager, but it is difficult to confirm whether it is sufficiently removed from the risk of lightning strike, so that the main power is kept cut off, or There are problems with managing the restoration of the main power source.

In addition, in the step S500, the control unit 140 measures the generation of brain discharge and the thundercloud detected for each monitoring area within a preset time after outputting the first brain discharge alarm based on the measurement value of the electric charge induced in the brain discharge and the thundercloud. At least one of the values is used as a switching condition to determine whether to recover from the standby power to the main power or to maintain the switched state to the standby power.

Further, in the step S500, the control unit 140 sets the measurement value of the sensor unit 110 installed in the individual sensing area within a predetermined period of time after the first output of the brain discharge alarm under the switching condition for determining the restoration of the main power. Whether or not an additional brain discharge occurs in at least one monitoring area among the reference value, the warning area, and the target area, and whether additional brain discharge occurs in the attention area in any brain discharge alarm state When one or more conditions are matched by detection, the state in which the input power of the power equipment system 200 is supplied from the standby power is maintained.

Continuing, the control unit 140 determines whether to maintain the switched state to standby power or restore to main power using the analysis result of step S500 (S600).
