Description

Technical Field

[0001] The present invention relates to the technical field of electric meters, and in particular to an electric meter matching method, system electronic equipment, storage medium and program product. Background Art

[0002] In the power system, due to the independence between business systems, the same or similar data will have different forms in different systems, and sometimes even data conflicts will occur. The energy metering system (TMR) mainly uses energy meters to measure the electric energy of the power plant's on-grid, off-grid and tie-line gateways, which belongs to the secondary circuit wiring measurement; the main functions of the energy management system (EMS) also include data collection and monitoring, which is to measure the motion devices of the primary equipment. However, the TMR system uses a metering archive model, including metering terminals, metering meters, etc.; while the EMS system uses a power grid model, including transformers, windings, lines, line ends, and other models. The TMR system measures the power consumption of these devices through metering meters, while the EMS model measures the instantaneous power, voltage, current and other data of these devices through telemetry equipment. In fact, they are all measuring the same equipment. However, in the actual business system, the metering meter needs to be associated with the corresponding power grid model to support the business. Since the TMR system and the EMS system are two independent systems, they provide data separately when supporting the third-party business system. The third-party business system needs to manually associate and match the metering meter of the TMR system with the power grid model of the EMS (mainly by name). This method is inefficient and cumbersome. Moreover, after the association error of individual equipment, it is impossible to effectively troubleshoot. The industry lacks a simple and effective technical solution to solve the above problems. Summary of the invention

[0026] The object of the present invention is to provide an electric meter matching method, system, electronic equipment, storage medium and program product to achieve automatic matching between a TMR system electric meter and an EMS system.

[0027] Please refer to Figure 1 , Figure 1 The following is a flow chart of an electric meter matching method provided by an embodiment of the present invention. Figure 1 To achieve the above object, the present invention provides an electric meter matching method, comprising the following steps:

[0028] Obtain the daily collected electricity of the TMR system meter of any equipment in the plant; obtain the daily integrated electricity of the EMS system of the equipment;

[0029] Obtaining the daily collected power and the daily integrated power of the device for multiple consecutive days;

[0030] Calculate the correlation coefficient between the daily collected power and the daily integrated power of the device according to the daily collected power and the daily integrated power of the device for multiple days;

[0031] Calculate the deviation rate between the daily collected power and the daily integrated power of the device according to the daily collected power and the daily integrated power of the acquired multiple days;

[0032] A determination is made for the device. If the correlation coefficient of the device is greater than a first preset threshold and the deviation rate of the device is less than a second preset threshold, the TMR system electric meter of the device is matched with the EMS system of the device.

[0033] With such a configuration, the present invention uses the two indicators of correlation coefficient and deviation rate to study the correlation between the daily collected electricity and the daily integrated electricity, thereby achieving the matching of the TMR system meter and the EMS system from the underlying algorithm level. The operation and maintenance personnel only need to check the results of the automatic matching in the end, and manually associate the very few meters and power grid models that fail to match. The vast majority of meters and power grid models can be matched automatically, which greatly improves the matching efficiency and accuracy of the metering meter and the power grid model, reduces the workload of the operation and maintenance personnel, and improves work efficiency.

[0034] It should be noted that the daily collected power and the daily integrated power both include positive active power and reverse active power, and power consumption and transmission have specific directions and properties. When the power flows to the user, we call it positive active power, which is the actual energy consumed, usually measured in kilowatt-hours (KWh). The calculation of this power is based on the integration of active power over time. In contrast, reverse active power is the energy generated when power flows from the user to the system. In a three-phase three-wire power meter, these energies are subdivided into positive active power, positive reactive power, reverse active power, and reverse reactive power. The measurement of power involves the assumption of direction, and it is generally assumed that the direction from the system to the user is positive. Therefore, when power flows from the system to the user, it is regarded as positive power; conversely, when power flows from the user to the system, it is reverse active power. From the perspective of the power consumption side, positive active power represents the consumption of power, while reverse active power indicates that power is being transmitted to the system. The transmission of these energies actually occurs and may be caused by a variety of situations, such as the power generation of the user's internal power generation equipment is greater than the power consumption, or the large equipment continues to operate and turns into a generator at the moment of power outage. It should be noted in this application that the daily collected power and the daily integrated power of the forward active power correspond to the research, and the daily collected power and the daily integrated power of the reverse active power correspond to the research, which should not be confused and will not be repeated here.

[0035] It should be understood that some electric meters need to use the voltage and current transformer of the electric meter for transformation ratio because the corresponding equipment voltage and current are large, so there is a multiplier. Therefore, the multiplier as a parameter should be considered in the calculation process in this case. Based on this, the present invention further provides the following technical solutions:

[0036] The obtaining of the daily collected power of the TMR system electric meter of any equipment of the plant station specifically includes:

[0037] Obtain the first frozen indication of the electric meter of the device at zero o'clock on the day;

[0038] Obtain the second frozen indication of the electric meter of the device at zero o'clock on the previous day;

[0039] Get the multiplier of the electric meter of the device;

[0040] The daily collected power is obtained according to the first frozen indication, the second frozen indication, and the multiple.

[0041] Specifically, it can be calculated according to the following relationship:

[0042] Energy = (final code - initial code) * multiplier

[0043] in

[0044] The last bottom code is the meter's frozen indication at 0:00 on the day;

[0045] The initial code is the meter's frozen indication at 0:00 the previous day;

[0046] The ratio is the voltage and current transformer ratio of the meter.

[0047] Specifically, obtaining the daily integrated power of the EMS system of the equipment of the plant station specifically includes:

[0048] Setting a preset number of collection moments and obtaining the power of the device at any collection moment, in an exemplary embodiment;

[0049] Calculating the average power of the device according to the acquired power;

[0050] The daily integrated power is obtained according to the average power.

[0051] Specifically, it can be calculated according to the following relationship:

[0052]

[0053] P i is the power data at a certain moment; n is the number of power data. (Normally, it is 288, i.e. one data point every 5 minutes)

[0054] More specifically, calculating the correlation coefficient between the daily collected power and the daily integrated power of the device based on the daily collected power and the daily integrated power of the acquired multiple days specifically includes:

[0055] The Pearson correlation coefficient between the daily collected power and the daily integrated power of the device is calculated based on the daily collected power and the daily integrated power of the device for multiple days.

[0056] The Pearson correlation coefficient formula is as follows:

[0057]

[0058] in:

[0059] r is the Pearson coefficient;

[0060] n is the total number of days, for example, if n is 30, the daily collected power and the daily integrated power for 30 days are obtained;

[0061] X i Collecting the power value for the i-th day among n days;

[0062] Y i Collecting the power value for the i-th day among n days;

[0063] is n Xi The average value of

[0064] is n Y i The average value of .

[0065] The Pearson correlation coefficient indicates the correlation between two sets of data, and its value range is [-1,1], where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no linear correlation.

[0066] Further, the calculating the deviation rate between the daily collected power and the daily integrated power of the device according to the daily collected power and the daily integrated power of the acquired multiple days specifically includes:

[0067] Calculate the average daily power collected by the device over multiple days;

[0068] Calculate the average daily integrated power of the device over multiple days;

[0069] The deviation rate between the daily collected power and the daily integrated power of the device is calculated according to the average daily collected power and the average daily integrated power.

[0070] Specifically, the calculating, according to the average daily collected power and the average daily integrated power, a deviation rate between the daily collected power and the daily integrated power of the device specifically includes:

[0071] Taking the absolute value of the difference between the average daily collected electricity and the average daily integrated electricity as the numerator, and the average daily collected electricity or the average daily integrated electricity as the denominator (that is, the denominator can be either one of the two, but once it is determined to use one of them, the same parameter must be used uniformly), calculate the deviation rate between the daily collected electricity and the daily integrated electricity of the device.

[0072] In an exemplary embodiment, the first preset threshold corresponding to the Pearson correlation coefficient is set to 0.95, and the second preset threshold corresponding to the deviation rate is set to 0.05.

[0073] After completion, the data accuracy can be manually checked. After the meter is automatically matched with the grid model, it is manually confirmed based on the meter name and grid model name. For very few devices that cannot be automatically associated due to data quality issues, the data is manually processed.

[0074] To achieve the above object, the present invention further provides a matching system, comprising:

[0075] The first acquisition module is used to obtain the daily collected power of the TMR system meter of any equipment in the plant;

[0076] The second acquisition module is used to obtain the daily integrated power of the EMS system of the device;

[0077] A third acquisition module is used to acquire the daily collected power and the daily integrated power of the device for multiple consecutive days;

[0078] A first calculation module is used to calculate the correlation coefficient between the daily collected power and the daily integrated power of the device according to the daily collected power and the daily integrated power of multiple days obtained;

[0079] A second calculation module is used to calculate the deviation rate between the daily collected power and the daily integrated power of the device according to the daily collected power and the daily integrated power of multiple days obtained;

[0080] The determination module is used to determine the device, and if the correlation coefficient of the device is greater than a first preset threshold and the deviation rate of the device is less than a second preset threshold, the TMR system meter of the device is matched with the EMS system of the device.

[0081] Since the matching system is used to execute any of the above-mentioned meter matching methods. Therefore, the matching system can use the two indicators of correlation coefficient and deviation rate to study the correlation between the daily collected electricity and the daily integrated electricity, thereby realizing the matching of the TMR system meter and the EMS system from the underlying algorithm level.
