Description

Technical Field

[0001] The invention relates to the technical field of line energy consumption monitoring, and in particular to an energy consumption monitoring and evaluation system for a photovoltaic field collector line. Background Art

[0002] The collector line is an important component of the power system. It is mainly responsible for collecting the electric energy generated by each power generation unit or power generation equipment and transmitting it to the booster station or switch station. This process is particularly critical in photovoltaic power generation systems and wind power generation systems. The role and characteristics of the collector line are different. In the photovoltaic power generation system, the collector line is a DC and AC transmission line that combines the electric energy output by each photovoltaic module string to the inverter through the combiner box and collects it to the power generation bus through the inverter output end. This process involves transmitting the electric energy output by the local booster transformer to the power generation bus to ensure the effective transmission and utilization of electric energy.

[0003] However, the current design institutes are still in the early stages of understanding the parameters of the collector line and the loss of the collector line. When designing, they often fail to take into account the unfavorable conditions such as the large capacity of the collector line and the energy consumption and voltage drop loss caused by the long distance. There is a lack of relevant calculation and research methods for the loss calculation of the collector line. Designers cannot fully grasp the parameters of the collector line and cannot accurately determine the problem when the system operates abnormally. In addition, there is a lack of data verification and identification process in the loss calculation of the collector line, and it is impossible to supervise and analyze the validity and accuracy of the data from the front end, middle end and back end, thereby reducing the accuracy and reliability of subsequent analysis results.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an energy consumption monitoring and evaluation system for a photovoltaic field collector line to solve the above-mentioned technical defects. The present invention analyzes from three points: the front end, the middle end, and the back end. On the one hand, it helps to track and verify the data, and on the other hand, it helps to ensure the accuracy and reliability of the energy consumption analysis results, so as to understand whether the current photovoltaic field collector line design scheme meets the requirements so as to make timely changes.

[0007] After receiving the supervision instruction, the information collection unit immediately collects and stores the monitoring data and transmission risk information of the photovoltaic field energy consumption collection equipment. The information supervision unit is used to retrieve the monitoring data, and perform information deviation supervision evaluation analysis on the monitoring data, compare and analyze the obtained information deviation value and interference risk value, and obtain normal signals and abnormal signals;

[0008] The missing analysis unit is used to respond to the normal signal and retrieve the transmission risk information, and at the same time perform information transmission verification feedback evaluation analysis on the transmission risk information, compare and analyze the obtained actual character string with the verification character string to obtain the standard signal and the missing signal;

[0009] The energy consumption accounting unit is used to respond to standard signals and perform intelligent energy consumption calculation, evaluation, processing and analysis at the same time, to judge and process the energy consumption of each section of the collection line or the energy consumption of each collection line, and to send the obtained feedback signal to the display management unit, and to verify, match, supervise and analyze the table of imported original data, and to send the obtained qualified signals and unqualified signals to the display management unit.

[0011] Set the monitoring cycle and set it as the time threshold to obtain the monitoring data of the collector line energy consumption collection equipment in the photovoltaic field within the time threshold. The monitoring data includes information deviation value and interference risk value. The information deviation value and interference risk value are compared and analyzed with the preset information deviation value threshold and preset interference risk value threshold stored in the internal input:

[0012] If the information deviation value is less than the preset information deviation value threshold, and the interference risk value is less than the preset interference risk value threshold, a normal signal is generated;

[0013] If the information deviation value is less than the preset information deviation value threshold, and the interference risk value is less than the preset interference risk value threshold, an abnormal signal is generated.

[0014] Preferably, the information deviation value indicates the number of deviations between the monitoring and collection time of the energy consumption collection device and the preset monitoring and collection time; the interference risk value indicates the product value obtained by multiplying the external interference value and the self-interference value after data normalization processing, the external interference value indicates the duration of the overlap corresponding to the corresponding value of the environmental parameter exceeding the preset threshold, the environmental parameters include temperature and humidity, and the self-interference value indicates the historical abnormal frequency of the energy consumption collection device itself, and the historical abnormalities include failures and high loads.

[0017] The number of bytes transmitted after the original data transmission in the analysis period is obtained, and text characters are extracted from the number of bytes transmitted after the original data transmission. The string composed of the text characters extracted from the number of bytes transmitted after the original data transmission is set as the actual string, and the actual string is compared and analyzed with the verification string one by one:

[0018] If the actual string corresponds to the verification string one by one, a standard signal is generated;

[0019] If the actual string does not correspond to the verification string one-to-one, a loss signal is generated;

[0020] The transmission obstruction value indicates the overlap duration between the duration corresponding to the packet loss rate of the transmission network exceeding the preset packet loss rate threshold and the transmission freeze duration.

[0021] Preferably, the energy consumption intelligent calculation, evaluation, processing and analysis steps of the energy consumption accounting unit are as follows:

[0022] Step 1: Establish a database of structures and electrical parameters of various types of cables and overhead lines, uniquely identify each conductor model and transformer capacity, write algorithm formulas for various energy consumption, and edit and import raw data;

[0023] Obtain the table for importing the original data, and conduct verification, matching, supervision and analysis on the table for importing the original data to determine whether the original data import is qualified. If a qualified signal is obtained, proceed to step 2; if an unqualified signal is obtained, feedback and adjustment are given;

[0024] Step 2: Use different line types to design conductors of different models in the existing software, and design them one by one according to the transformer capacity and conductor model identification in the electrical parameter database. After completion, the conductor model, length, and the starting and ending points of the connection are automatically exported into a table;

[0025] Step 3: After inputting the set threshold parameters, the series connection of each collector line can be automatically completed, and the energy consumption of each collector line or each collector line can be calculated;

[0026] Step 4: The energy consumption of each section of the collector line or each collection line is judged and processed. If the energy consumption of each section of the collector line or each collection line exceeds the preset threshold, a feedback signal is generated. If the energy consumption of each section of the collector line or each collection line exceeds the preset threshold, no signal is generated.

[0027] Preferably, the verification matching supervision analysis process of the energy consumption accounting unit is as follows:

[0028] The number of data format errors and sorting difference values ​​in the process of converting the original data during the analysis period are obtained. The sorting risk value refers to the number of differences between the sorting order of enterprise project data and the preset sorting order. The number of data format errors and sorting difference values ​​are discriminantly analyzed respectively:

[0029] If the number of data format errors is zero, an accurate signal is generated;

[0030] If the number of data format errors is not zero, a deviation signal is generated;

[0031] If the sort difference value is zero, a corresponding signal is generated;

[0032] If the sorting difference value is not zero, a non-corresponding signal is generated, and the accurate signal, deviation signal, corresponding signal, and non-corresponding signal are interactively analyzed:

[0033] If an accurate signal and a corresponding signal are generated, a qualified signal is obtained;
