Description

Optimal operation control remote monitoring device for power saving of electric equipment {THE APPARATUS OF MONITORING FOR BEING MOST SUITABLE CONTROL}

The present invention is installed on one side of an electrical device (air conditioner, refrigerator, washing machine, TV, computer) to monitor the power consumption analysis data of the user and the external environment changes (weather, temperature, humidity), so that the different electrical devices are efficiently The present invention relates to an optimal operation control remote monitoring device for power saving of electric equipment that can be controlled 1: 1 by situation so that it can operate.

Korea's power consumption is increasing every year due to the rapid increase in energy consumption due to cultural convenience and the energy-saving industrial structure. (The average power consumption in 2011 increased by 1,865 [10,000 kW] compared to 2006. The energy supply and demand problem in Korea, which imports more than 97 [%] of energy, is very serious.

In addition, the power consumption pattern of Korea is very large in terms of demand fluctuations (air-conditioning and demand) depending on the weather conditions during the summer and winter seasons. The maximum power demand in 2010 was 3 pm on August 20, at 667.44 million kW (2009). 10.6%), an increase of 689.8 million kW.

This is presumed to be a surge in air conditioner use due to temperatures higher than normal.

On the other hand, Korea's current power consumption pattern should pay attention to the steep increase in peak power demand due to the heating load in winter, rather than the cooling load in summer, which has traditionally used a lot of electricity. In 20011, 7.313.7 million kW was increased to 1067.2 million kW over two years. It is estimated that the late-night heating load increased rapidly as the cold weather continued compared to the average year due to the abnormal climate caused by global warming.

 As mentioned above, the peak power demand is also increasing due to the surge in the use of air conditioners in the summer and winter, which are sensitive to changes in the climate change. Accordingly, Korea has the power reserve to secure stable power supply even at the maximum power demand. Annually adds power generation facilities.

However, since 2013, the developing countries including Korea have been expected to participate in the CO2 burden and reduction, which means that there are many difficulties in the expansion of power generation facilities and energy supply.

In order to solve this problem, in the prior art, when the user does not consume power, the standby power is cut off through wired / wireless communication or a programmed command, and only by distributing energy by monitoring the total power consumption of the user. As a result, when the time and place are changed, there is a problem that the standby power and power consumption must be checked again according to the change of weather and climate, and the device must be changed.

In other words, it is urgent to develop a device that can analyze the power consumption according to the change of weather and climate and check and set the maximum efficient driving point according to the analyzed data and the installation place and usage environment of the actual electric devices. It is true.
