Generally, in a power system, a control system manages the storage of idle power for power stabilization and power quality stabilization. For example, an uninterruptible power supply (UPS) device overcomes unexpected power failures that can occur in a commercial power supply to provide good quality stable power.

In addition, the Energy Storage System (ESS) stores preliminary power in advance and supplies stable power to the reserve power stored in an emergency situation such as power failure. Uninterruptible power supply (UPS) and energy storage system (ESS) are being introduced to ensure reliability of power supply in various fields such as finance, broadcasting, and industry where stable supply of electric power is important.

In recent years, the issue of depletion of energy resources by fossil fuels, issues of environmental pollution, and economical efficiency of energy use have been highlighted, thereby effectively overcoming the inconsistency between power consumption and electric power production, And a smart grid system that flexibly adjusts the power supply amount in connection with various information communication infrastructures in order to solve an overload phenomenon due to power shortage.

The Smart Grid system includes a plurality of constituent facilities corresponding to the subject of production or consumption of electric power. Among the above facilities on the smart grid, distributed power generation facilities having power generation facilities (for example, facilities having self power generation facilities such as solar heat and wind power generation) store the developed power when the power consumption is small, and when the power consumption is large, To the consumer along with the production power.

That is, the Smart Grid system is a form of next generation power network utilizing information communication technology in the power network. The Smart Grid system includes a network metering system that includes smart meter information and an overlay of an existing power grid that includes consumer power usage information so that power can be controlled via two- Thereby increasing energy savings, reliability and transparency.

This Smart Grid system was selected as one of the three technologies by the US Economic Weekly Business 2.0 to introduce eight technologies to save mankind from climate change and environmental pollution caused by global warming.

The industrialization of mankind has had difficulties in securing energy due to the increase in energy consumption, and it has caused excessive emission of CO ₂ , which is the main cause of global warming. The smart grid system is an energy-saving power grid capable of solving such a serious problem of energy security and global warming.

The Smart Grid system reduces energy waste by improving energy efficiency, and reduces dependence on energy overseas through activation of distributed generation based on renewable energy and reduction of greenhouse gas by reducing use of fossil fuel in existing power generation facilities. You can call it.

In addition, each country that promotes the above-mentioned Smart Grid system is striving to construct a demonstration complex. It is expected to test the energy, economy, and industrial success of the Smart Grid industry through the creation of a Smart Grid Demonstration Complex.

In Korea, the government plans to implement a nationwide Smart Grid, reducing energy by 2% by 2030, cutting 41 million tons of national greenhouse gas emissions from the environment (7% of 2006 emissions), and importing fossil fuel And a $ 10 billion reduction in energy imports. In addition, through the creation of a demonstration complex in Jeju area, Jeju is expected to have an economic and industrial positive effect through economic revitalization, youth unemployment resolution, and overseas market entry.

The Smart Grid system is provided by a device that senses, measures, and controls information about the grid state in a bi-directional manner to system users, operators, and automated devices for electrical generation, transmission, distribution, and consumption of the power grid.

In order to provide such smart grid technology, the technology range is as wide as the complexity of the technology such as transmission network, distributed automation, demand response (Demand Response, DR), Advanced Metering Infrastructure (AMI) .

As a result, smart grid technology has been studied extensively, and its market size is expected to continue to rise. Standardization is being actively carried out by international and international standardization organizations for smart grid related standardization.

Technologies for implementing the Smart Grid system can be divided into a distributed power source field, a power network management field, and a user power management field. In the field of distributed power generation, there are distributed power supply technology and energy storage integration technology. In the power network management technology, real-time monitoring technology, transmission and distribution automation (DR) technology, and Communication Network technology. In the field of user power management, there are Smart Meter, Smart Building, Smart Appliances (Smart Appliance), and Consumer Voltage Regulation technology.

In such a smart grid system, distributed generation facilities are introducing uninterruptible power supplies (UPS) and energy storage devices (ESS) for power stabilization. Meanwhile, the smart meter is an Advanced Metering Infrastructure (AMI) that performs power metering to measure power consumption of a power consumer such as a home / apartment / building that consumes power, Transfer the information to a separate operation center.

However, the existing smart meter, that is, the advanced metering infrastructure (AMI) is embedded in a specific place such as a home / apartment / building or the like, and it is difficult for the individual manager to directly recognize the power consumption of the power consumption end- .

On the other hand, the electric power supplied to the installation place where the existing smart meter is installed is distributed through the distribution board and supplies power to a plurality of loads. For example, when the installation location is a large building, the total power supplied to the large building is distributed to each floor (i.e., a plurality of loads) and supplied with power.

In this case, the conventional smart meter can only calculate the power amount of the entire installation site (that is, the large building in the above example), and the current flowing in each load (that is, each floor in the above example) The amount of power consumed by each load can not be calculated.

Hereinafter, the components of the multi-channel power amount measuring means 100-1 to 100-N will be described in more detail with reference to FIG.

That is, the multi-channel current and voltage detection module 110 is indirectly connected detachably to power lines P1 to PN, which are drawn into a customer and distributed to a plurality of power lines, As shown in FIG.

The multi-channel current and voltage detecting module 110 is detachably connected to each of the power lines P1 to PN and detects a current and a voltage flowing through the power lines P1 to PN by an electromagnetic induction phenomenon or a current- And the output terminals O1 to ON of the current and voltage sensing units 111-1 to 111-N are detachably connected to the current and voltage sensing units 111-1 to 111-N, respectively, And a plurality of connection connectors (not shown) provided to transmit the analog current and voltage signals output from the output terminals O1 to ON of the current and voltage sensing units 111-1 to 111-N to the input side of the control module 130 112-1 to 112-N.

At this time, the plurality of current and voltage sensing units 111-1 to 111-N are generated by at least one current transformer (CT) having a clamp type or a current flowing in each power line (P1 to PN) At least one hall sensor for converting an analog voltage signal into an analog current signal and detecting a current and a voltage flowing through each of the power lines P1 to PN, And the like.

3, the Hall sensor is a voltage and current sensor having a high responsiveness to convert the intensity of the current magnetic field into a voltage. As shown in FIG. 3, the Hall sensor is formed by disposing a magnetic core 20 and a Hall element 30 between the gaps.

First, the Hall Effect, which is the basic principle of the Hall sensor, will be described. The Hall Effect was discovered by E.H. Hall, a US physicist in 1879. When a solid such as a metal or a semiconductor is placed in a magnetic field and a current is flowed in the solid at a right angle to the direction of the magnetic field, an electric field appears in the solid at right angles to each of the two directions. When particles (for example, electrons) bearing charges (electrons) move in a magnetic field while they are called Hall electromotive force (electromotive force), the motion direction is bent by the force of Lorenz.

Therefore, an electric field appears because the current flow in the solid is shifted to one side and the distribution of charge becomes unbalanced. Even if the electric current is in the same direction, the direction of the electric field generated according to the positive and negative charges of the electric charge (electrons are negative) is different, and the electric field intensity also varies depending on the concentration of the particles. Using these effects, we measure the concentration and mobility of electrons (especially, 'free electrons') that carry current in a solid. Especially in semiconductors, we measure free electrons with free electrons Identification and measurement can also be done.

By this Hall effect, the induced electromotive force (Hall electromotive force) Vh proportional to the current I flowing on the power lines P1 to PN is measured with high sensitivity and the voltage and current can be measured from this electromotive force .

Hereinafter, the measurement principle will be described in detail. When a current (for example, DC, AC, DC + AC, etc.) I flows through the power lines P1 to PN, a magnetic flux B proportional to the current I is generated in the gap, .

When a control current IC flows in a direction perpendicular to the magnetic flux B in this state, a voltage Vh proportional to the bus current I is generated between the terminals a-b.

Although the Hall voltage Vh of the hall sensor is a minute voltage of several tens of mV, an amplifier may be used to amplify the output. The Hall voltage is output according to the following Equation (1).

(Equation 1)

Vh = K * Ic * B (Vh: Hall voltage, K: red sensitivity constant, IC: control current, B: magnetic flux density)

As described above, the Hall sensor can measure DC, AC, and DC + AC. Second, it is completely isolated from the semiconductor to be measured. Third, there is an advantage that there is no power loss, the response characteristic is quick, the linearity is excellent, the structure is simple, and the reliability is good.

For example, when the plurality of current and voltage sensing units 111-1 to 111-N include the hall sensor, a Hall voltage due to a magnetic field induced in each power line P1 to PN is generated through the core 20 A differential amplifier (not shown) for differentially amplifying the output signal of the Hall element 30 to a predetermined level; a differential amplifier (not shown) for filtering the output signal of the differential amplifier to output only a signal of a predetermined band A band pass filter (BPF) (not shown), and the like.
