Definitions

• the present invention relates to a meter which is placed on the main line for detecting and calculating the technical losses in the electric networks and which can measure and record both the electric energy and the current with the electric network voltage and the outputs which are connected to this line and also the end point where the electric energy is used. And the present invention relates to a system and a method, which are formed by means of meters simultaneously synchronizing the electric network voltage and current at the point of consumption.
• Electricity meters are used to measure the energy consumed in the electricity grid, and these meters record the energy consumed at all the consumption points connected to the network. Some of these meters also measure the network voltage at the point they are connected to. However, the meters are read independently and the consumption invoices are only issued and subscriptions are given over the consumption amounts. For example, it is not possible to calculate how much technical loss is lost in a network or a power distribution unit system and how much of the non-technical loss-leakage amount is calculated, and therefore the difference between the total of the meters obtained from the month- end consumption quantities and the record made by the meter on the main circuit where all meters are connected Which is expressed as the amount of loss of the line or power distribution unit zone and is reflected in the records as well. It is not known how much of the technical loss and how much of the detected number is the leakage amount.
• Figure 1 Electrical system a meter or meter system that simultaneously measures and records electrical energy and voltage consumed by a measuring instrument or meter that simultaneously measures and records electrical energy and voltage consumed over the electric network line, and the associated line in the housing.
• Figure 2 Actual mode of operation and system modeled by schematic notation.
• Electric network meter or power distribution unit meter (1) consumed energy and at the point where it is connected by simultaneously measuring the network / circuit voltage and storing it at specified intervals recordings moving from the main line to the end user connected to the main line the subscriber electricity meters (3) on the outgoing lines simultaneously record the energies consumed in the subscriptions and the network / circuit voltage at the connected point and store them in memory at specific time intervals.
• Both the main branch meter or the power distribution unit gauge (1) and the connected subscriber electricity meters (3) in the lines leading to the main branch contain the real time clock.
• the clock precision will advance at the same time in all meters or measuring instruments. The goodness of the clock precision is important because the values taken are synchronous and the results are closest to reality.
• Obtained energy consumption measurements and electric network voltages are recorded both at the point of connection of the measuring instruments or meters and in the memory of the main meter or power distribution unit meter (1) and at the same time and at the same interval to the memory of the subscriber electricity meters (3) Are recorded.
• the electricity is transmitted to the various points via the energy transmission line (2) and there is one subscriber electricity meter (3) at each consumption point.
• the equivalent resistance or impedance (11) of the conductive wires which are shown on the main line and the other lines connected thereto, and which carry the energy between the two electric meters, are formed.
• the voltage or voltage (6) measured in the main branch meter has to be equal to the voltage (10) formed on the energy-carrying conductive wires between the two electricity meters and the vector sum of the voltage or voltage (7) measured in the subscriber electricity meter.
• the energy loss on the power transmission line 2 between the two electricity meters is directly proportional to the magnitude of the voltage difference between the voltage or voltage 6 measured at the base line meter and the voltage or voltage 7 measured at the subscriber meter.
• the energy consumed by the subscriber would be the same as the total energy (8) measured in the main line meter if it did not create a voltage drop across the
• n Number of Users
• Wn Represents the total amount in a time period of the number of subscribers or users, the combination of real and virtual energy.
• Vn indicates the electric network voltage or voltage at the number of subscribers or users.
• the loss of the total amount of energy (9) measured in the subscriber meter on the conductors occurs at a voltage (10) on the energy-carrying conductor wires between the two electricity meters. Therefore, when the total amount of energy (9) measured in the subscriber meter is measured simultaneously, the voltage in the main circuit is reflected to the main branch meter or the power distribution unit meter (1) at the voltage or voltage (7) measured at the subscriber electricity meter.
• the technical loss on the conductors from the first point to the last point is determined by subtracting the voltage or voltage (6)by subtracting the measured voltage or voltage (7) from the electric meter and multiplying the voltage or voltage (6) measured in the main line meter by the scalar by multiplying the total energy (9) measured in the subscriber electricity meter by the scalar. Therefore, when all the meters or measuring instruments connected to the system simultaneously and periodically record both the energy passing through them and the voltage, the sum of the values obtained by calculating the technical losses on the conductors for the whole system will also be the technical loss of the whole system. Thus, not only in one case, but in all the houses, technical losses will be calculated.
• the main register or the power distribution unit meter (1) and the subscriber at all energy consumption points (3) will be able to obtain more precise results during the time interval of the records kept simultaneously and intermittently. If the mentioned subject matter records are made in very short intervals, real and individual results will be obtained. According to the results of calculations made in accordance with Figure 2, the total energy (8) recorded in the main line meter and the total energy measured in the subscriber meters in all other collectors The difference between them gives total energy loss.
• This total loss includes the technical losses due to the current drawn by the subscriber registered in the system of the electricity distribution companies, ie losses due to the equivalent resistance of the energy transmission lines (2) and due to the flow of heat generated by the subscriber, and the leakage of electricity outside these known technical losses
• the sum of the technical losses created by each subscriber gives a total technical loss which can be calculated and calculated in the energy transmission line (2). When the calculated technical loss is subtracted from the total loss, the use of illegal energy and the technical loss resulting from this use remain.
• This difference which is known as the amount of leakage, includes both illegal use and technical loss due to illegal use, which is obtained by multiplying the actual leak amount by a certain ratio.
• the actual leakage-based technical loss factor multiplier can be obtained by dividing the arithmetic mean difference of the difference between the arithmetic mean of the voltage (6) of the ratio meter (1) and the voltages (7) of the subscriber meters (3) Leakage and associated technical loss coefficient are obtained.
• the actual leakage is calculated by dividing the quantity found as illegal use by adding an additional coefficient to the coefficient and the difference between the calculated leakage and the actual amount of leakage found by the calculation also gives a technical loss due to actual illegal use.
• the total technical loss is equal to the sum of the technical loss due to the usage of the subscriber (3) and the technical loss due to the leakage usage and is calculated and determined.Thus, a system is established in which the total technical loss in a system in which electric energy is distributed, the leakage energy and the technical losses resulting from this energy can be separated from each other.
