Description

Technical Field

[0001] The invention relates to the field of photovoltaic shutdown system testing, and in particular to a testing device and a testing method for a photovoltaic transmitter. Background Art

[0002] In the field of safety control of photovoltaic systems, photovoltaic circuit breakers play a vital role. The photovoltaic circuit breaker system usually consists of two parts: a photovoltaic circuit breaker and a transmitter. Its working principle is based on the signal transmission and response mechanism: the transmitter is responsible for transmitting a specific signal, and the photovoltaic circuit breaker maintains its conduction state after receiving the signal to ensure the normal operation of the photovoltaic system; if no signal is received, the photovoltaic circuit breaker will automatically shut down to quickly cut off the power supply of the photovoltaic module in an emergency, a fault or when maintenance is required, thereby eliminating the DC high voltage, putting the system into a non-hazardous state, and ensuring the safety of personnel and equipment.

[0003] Currently, the power consumption test of the transmitter is one of the key indicators for evaluating its performance, which is directly related to the energy efficiency ratio and long-term operation stability of the transmitter. The traditional power consumption test method relies on the host computer system. When multiple transmitters need to be tested at the same time, the host computer in the traditional test method needs to frequently process and judge the power consumption data of each transmitter, which takes a long time and increases the occupation of system test resources, seriously affecting the overall test efficiency. In addition, frequent data processing and judgment also increase the load of the host computer, resulting in system stability being affected; finally, since the transmitter continues to send power carrier signals during the test, the power consumption of the transmitter is prone to fluctuations, which may cause the host computer to misjudge and affect the test accuracy.

DETAILED DESCRIPTION

[0019] In order to make the technical solutions and beneficial effects of the present invention more clearly understood, the following is a detailed description by listing specific embodiments. Unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0020] Figure 1 This is a schematic diagram of the structure of a photovoltaic transmitter test device provided in one embodiment of the present application. Figure 1 As shown, the test device includes: multiple test pin boards, multiple test base boards, a communication bus and a host computer; wherein the test base board is connected to the photovoltaic transmitter to be tested through the test pin board, and is used to perform performance tests on the photovoltaic transmitter to be tested; specifically, one end of each test pin board is connected to the test point of the photovoltaic transmitter to be tested through a test pin, and the other end is connected to the corresponding test base board through a wiring; each test pin board and the corresponding test base board form a test channel; the host computer is connected to the multiple test base boards through the communication bus, and is used to interact with each test channel for test instructions and test results. The photovoltaic transmitter is applied to the photovoltaic system, which includes an inverter, a photovoltaic string and a photovoltaic transmitter; the photovoltaic string includes a plurality of photovoltaic units, each photovoltaic unit includes a photovoltaic switch and a photovoltaic module connected to the photovoltaic switch; the inverter is used to convert the direct current output by the photovoltaic string into alternating current and output it, the transmitter is used to send a conduction signal to the photovoltaic switch in the photovoltaic string at a fixed time period, the photovoltaic switch is used to maintain the output of the photovoltaic module when the conduction signal is received, and disconnect the output of the photovoltaic module when the conduction signal is not received; the transmitter and the photovoltaic switch communicate through the power line. It should be noted that the transmitter of the embodiment of the present application can be a transmitter that only has the function of transmitting the conduction signal, or it can be a transceiver that has the function of sending and receiving signals; correspondingly, the photovoltaic switch can be a switch that only has the function of receiving signals, or it can be a switch that has the function of sending and receiving signals.

[0021] The host computer is used to send a test signal to the test channel, wherein the test signal includes a preset response time T w and preset threshold range [P L ,P H ]. For example, Figure 1 As shown, the test device includes 8 test channels, and the communication addresses are 0x01, 0x02...0x08 respectively. The host computer sends test signals to the test channels of the corresponding communication addresses through command messages. It should be noted that the test signal in this application refers to the power consumption test instruction. Correspondingly, the test baseboard collects and judges the power consumption data after receiving the test signal.

[0022] Each test base plate is used to receive a test signal, collect the test point power consumption data of the corresponding photovoltaic transmitter to be tested according to the test signal, and calculate the power consumption data of the test point according to the test point power consumption data and the preset threshold range [P L,P H At the preset response time T w It is necessary to explain that the test board continuously collects data and processes and judges the data at the same time, and does not judge after obtaining all the data within the preset response time Tw.

[0023] As an optional specific implementation, the photovoltaic transmitter to be tested sends a turn-on signal at a fixed time period, thereby simulating the actual operating state of the photovoltaic transmitter to be tested, which is conducive to obtaining accurate power consumption data. It should be noted that the power consumption of the photovoltaic transmitter to be tested is divided into dynamic power consumption and static power consumption. The dynamic power consumption mainly refers to the power consumption generated in the process of sending the turn-on signal, and the static power consumption mainly refers to the power consumption not in the process of sending the turn-on signal. The dynamic power consumption data of the photovoltaic transmitter to be tested may fluctuate due to its continuous sending of the turn-on signal; on the other hand, since the turn-on signal is transmitted through the power line, the turn-on signal may also interfere with the transmission process of the test point power consumption data, affecting the accuracy of the test point power consumption data.

[0024] As an optional specific implementation, judging whether the power consumption of the photovoltaic transmitter to be tested is qualified within a preset response time according to the power consumption data of the test point and a preset threshold range includes: If the preset fixed time T of the acquisition s The average value of the power consumption data of the internal test points is within the preset threshold range [P L ,P H ], the test result is judged as qualified, and correspondingly, the qualified judgment result is sent to the host computer; If the preset fixed time T of the acquisition s The average value of the power consumption data of the internal test points is not within the preset threshold range [P L ,P H ], the test result is judged as unqualified; then continue to collect the next preset fixed time T s Test data within mT s The average value of the power consumption data of the test points within the preset threshold range [P L ,P H ], the test result is judged as qualified, and accordingly, the qualified judgment result is sent to the host computer; if it is not until NT s The average value of the power consumption data of the test point within the time is not within the preset threshold range [P L ,P H ], the test result is judged as unqualified, and correspondingly, the unqualified judgment result is sent to the host computer; where N≥m, (N+1)T s >T w .

[0025] Figure 2 FIG. 1 is a schematic diagram of a test process of a specific implementation method of the present application. Figure 2 As shown in FIG. 1 , after receiving the power consumption test signal, the test board starts the test process. The acquisition and processing module in the test board can obtain the test point power consumption data of the photovoltaic transmitter to be tested through the electrical connection of the pin board, and pass the data to the control module of the test board. The control module sends the power consumption data to the control module at a preset fixed time T. s The data set collected is P={P 1 , P 2 , P 3 , ...P N}, the control module calculates the arithmetic mean of the data set to obtain the average power consumption P of the test point C If P C Within the preset threshold range, that is, P L <P C <P H , the control module sends the qualified judgment result to the host computer. If P C If it is not within the preset threshold range, the original data set is retained and the data collection time is increased to 2T S , that is, T is performed again S The collected data is collected in time and integrated into the data set P = {P 1 , P 2 , P 3 , ...P N , P N+1 , P N+2 , ...P 2N}, the control module calculates the arithmetic mean of the data set to obtain P C , if P C If the threshold is met, the qualified judgment result is returned to the host computer. C If the threshold interval is not met, repeat the above operation. s When P C The output threshold interval is still not met, and the waiting response time T W <(N+1)T s , then an unqualified result is returned.

[0026] As an optional specific implementation, a fixed time T is preset s According to the preset response time T w OK. Further, 5T s ≤T w ≤10T sThat is, during the waiting time of the host computer, each test channel can supplement 5-10 sampling sets and determine whether the average power consumption of the corresponding test point meets the preset threshold range, thereby improving the accuracy of the test results and reducing misjudgment.

[0027] As an optional specific implementation, the testing device also includes a power supply (not shown in the figure), which is connected to the test base plate and is used to supply power to the test base plate; the test base plate is connected to the photovoltaic emitter to be tested through a test pin board and is also used to supply power to the photovoltaic emitter to be tested.

[0028] In the embodiment of the present application, the test signal sent by the host computer includes a preset response time and a preset threshold range. After receiving the test signal, the test baseboard in each test channel samples and processes the power consumption data of the test point, and makes a judgment after each sampling preset fixed time. If it is judged to be qualified, the qualified result is sent to the host computer; if it is judged to be unqualified, the sampling and judgment are continued until it is judged to be qualified or exceeds the preset response time. In the embodiment of the present application, the test baseboard processes and judges the power consumption data of the test point, thereby significantly reducing the computing resources of the host computer, reducing the number of frequent judgments of its test results, and greatly improving the overall efficiency of the test device; secondly, the test baseboard will continue to sample to form a new data set when judging unqualified, and judge the data set, thereby effectively reducing the potential interference of the transmitter on the power consumption data due to the conduction signal process, significantly reducing the misjudgment phenomenon of the test results, and improving the accuracy of the test results; finally, within the preset response time, the test baseboard will perform multiple supplementary sampling sets, so that multiple judgments can be made, effectively reducing errors, and improving the accuracy and reliability of the test.
