Description

[0002] With the expansion of the power system and the increase in the proportion of renewable energy connected to the grid, the dynamic reactive power support capability of generator units has become a key indicator for ensuring the stable operation of the power grid.

[0003] As an important means of verifying the operating limits of the unit in inductive reactive mode, the generator leading phase test can not only determine the leading phase depth of the generator (i.e., the angle by which the stator current leads the terminal voltage), but also reveal the impact of system parameters, excitation characteristics and grid conditions on the stability of the unit. It is of great significance for optimizing the generator's power and power factor curves (PQ curves) and improving the grid voltage regulation capability.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] Figure 1 This is a schematic diagram of the structure of a generator phase-leading test management device provided in an embodiment of the present invention. Figure 2 A schematic diagram of the circuit structure in the generator phase-leading test management device provided in this embodiment of the utility model is shown below. Figure 1 and Figure 2 As shown, the generator phase advance test management device includes a housing 110, a communication port 120, multiple input signal terminals 130, an output signal terminal 140, and a main control system 150.

[0034] Input signal terminal 130, output signal terminal 140 and communication port 120 are all disposed on housing 110; communication port 120 is connected to the power plant's control system, output signal terminal 140 is connected to the power plant's excitation system, multiple input signal terminals 130 are respectively connected to multiple measuring instruments, and multiple measuring instruments are respectively disposed at multiple different measuring points of the generator in the power plant.

[0035] The main control system 150 collects the leading test data of the generator in real time through the communication port 120. The main control system 150 also collects the measurement data of the generator in real time through multiple input signal terminals 130. The main control system 150 also outputs control commands and test results to the excitation system through the output signal terminal 140.

[0036] The main control system 150 is housed inside the casing 110 and connected to various communication ports 120, multiple input signal terminals 130, and output signal terminals 140. The power plant's control system can be a distributed control system (DCS), capable of collecting various data and issuing control commands. The power plant's excitation system can control the generator's operation and the generator's phase advance depth during phase advance testing. Measuring instruments can be various types of data measuring instruments, and can be added adaptively according to the required data. For example, measuring instruments may include thermometers, voltage meters, and current meters, etc., without limitation.

[0037] Specifically, the generator leading phase test is an important grid-connected test to verify the generator's leading phase operation capability and PQ curve. Through leading phase depth tests at 50%, 75%, and 100% of rated active power, test data on the generator's leading phase capability and the main factors affecting it are obtained. During the generator leading phase test, the generator excitation current is reduced, causing the unit to gradually move from a lagging phase operation state to a zero reactive power state and then to a leading phase state. Various unit parameters need to be recorded during this process to determine the unit's status and test conditions. If any parameter reaches the leading phase operation limit, the test must be terminated and the leading phase depth result calculated. In this embodiment, the main control system 150 collects the leading phase test data in real time through the communication port 120 and the measurement data through multiple input signal terminals 130. This reduces the need for manpower, dispersed workstations, and inconvenient communication during the test, and minimizes the impact of human factors on the monitoring, analysis, and recording of test data. The main control system 150 can determine the generator's status and test conditions based on measurement data and leading-phase test data. When it is necessary to control the leading-phase depth of the generator or when a certain parameter reaches the leading-phase operating limit, the main control system 150 also outputs control commands and test results to the excitation system through the output signal terminal 140. This allows the excitation system to control the generator's operation, change the leading-phase depth, or terminate the test to meet the various test requirements in the leading-phase generator test. The main control system 150 can also analyze the test results, reducing the impact of human judgment on the extended test period and the problem of large errors in test result judgment, thus improving test efficiency. This device enables full-process control of data acquisition, data processing, and result analysis during the leading-phase generator test, providing test personnel with real-time, accurate, direct quantitative evaluation and analysis. This helps test personnel make timely and accurate judgments on the test results, reducing their workload and improving test efficiency.

[0038] This utility model provides a generator leading phase test management device, which includes a housing, a communication port, multiple input signal terminals, an output signal terminal, and a main control system. The input signal terminals, output signal terminals, and communication port are all located on the housing to facilitate connection between the communication port and the power plant's control system. This allows the device to collect leading phase test data of the generator during the leading phase test from the power plant's control system. The output signal terminals are connected to the power plant's excitation system to control the leading phase depth of the generator through the excitation system. The multiple input signal terminals are respectively connected to multiple measuring instruments, which are respectively installed on multiple generators in the power plant. The system uses multiple measurement points to collect measurement data that the power plant's control system cannot collect. The main control system collects the generator's leading phase test data in real time through the communication port and multiple output signal terminals. It also outputs control commands and test results to the excitation system through the output signal terminals. This enables full-process control of data acquisition, data processing, and result analysis during the generator's leading phase test, providing test personnel with real-time, accurate, direct quantitative evaluation and analysis. This helps test personnel make timely and accurate judgments on the test results, reduces the workload of test personnel, and improves test efficiency.

[0039] This utility model embodiment also provides another generator phase-leading test management device. Figure 3 A schematic diagram of the circuit structure in another generator phase-leading test management device provided in this embodiment of the present invention is shown below. Figure 3 As shown, optionally, the main control system 150 includes a data acquisition module 1501, a data processing module 1502, and an output module 1503.

[0040] The first input terminal of the data acquisition module 1501 is connected to the communication port 120, the second input terminal of the data acquisition module 1501 is connected to the input signal terminal 130, and the output terminal of the data acquisition module 1501 is connected to the first input terminal of the data processing module 1502. The data acquisition module 1501 is used to acquire phase advance test data and measurement data, and send the phase advance test data and measurement data to the data processing module 1502.

[0041] The output terminal of the data processing module 1502 is connected to the input terminal of the output module 1503. The data processing module 1502 is used to generate control commands and test results based on the phase test data and measurement data, and send them to the output module 1503.

[0042] The output terminal of the output module 1503 is connected to the output signal terminal 140. The output module 1503 is used to send control commands and test results to the excitation system.

[0043] The data acquisition module 1501, data processing module 1502, and output module 1503 are all housed within the casing 110. The data acquisition module 1501 is connected to the communication port 120 and the input signal terminal 130, while the output module 1503 is connected to the output signal terminal 140 to enable data input and output. Most of the data required for the generator leading phase test can be obtained through the power plant's control system connected to the communication port 120, such as generator active power, reactive power, excitation voltage, excitation current, stator core temperature, and plant auxiliary low-voltage bus voltage, which can be used as leading phase test data. Other data that need to be measured on-site, such as generator power angle and slip ring temperature, can be connected to the input signal terminal 130 via a cable through measuring instruments and introduced into the data acquisition module 1501 as measurement data.

[0044] Specifically, the data processing module 1502 can generate control commands and test results based on the leading phase test data and measurement data, and send them to the output module 1503. The output module 1503 then sends the control commands and test results to the excitation system. The excitation system can control the generator's operation during the leading phase test through the control commands, realizing full-process control of data acquisition, data processing, and result analysis during the leading phase test. This provides test personnel with real-time, accurate, direct quantitative evaluation and analysis. The test results can help test personnel make timely and accurate judgments on the test results, reduce the workload of test personnel, and improve test efficiency.

[0045] Furthermore, the data processing module 1502 can determine the validity of the data acquired by the data acquisition module 1501. For example, it can set a valid range for the data; if the data acquired by the data acquisition module 1501 is within the valid range, then the data acquired by the data acquisition module 1501 is deemed valid. The data processing module 1502 can also perform real-time calculations and judgments based on test limitations. When neither the leading-phase test data nor the measured data meets the test limitations, the output module 1503 sends a demagnetization command, allowing the excitation system to further increase the leading-phase depth based on the demagnetization command. If either the leading-phase test data or the measured data reaches an alarm value, the data processing module 1502 issues an alarm message via the output module 1503. If either the leading-phase test data or the measured data reaches a termination value, the data processing module 1502 issues test results and termination commands via the output module 1503. The test results include the generator's leading-phase depth. The termination command can control the generator's leading-phase test to terminate, stopping the generator's operation. The test results help test personnel make timely and accurate judgments about the test results, and timely control of the test process can greatly reduce the workload of test personnel and improve test efficiency.

[0046] Optionally, the leading phase test data includes the generator's active power, reactive power, power angle, terminal voltage, terminal current, excitation voltage, and excitation current.

[0047] Specifically, the power plant's control system is the power plant's DCS system. A communication connection is established with the power plant's DCS system through communication port 120. The generator's active power, reactive power, power angle, terminal voltage, terminal current, excitation voltage, and excitation current can be obtained from the power plant's DCS system.

[0048] Optionally, the measurement data includes the temperature at multiple measurement points on the generator end core and metal structural components, as well as the minimum bus voltage of the power supply connected to the generator and the voltage at multiple measurement points on the high-voltage side bus of the main transformer.

[0049] Specifically, there are approximately 300 measurement points on the generator end core and metal structural components, and approximately 50 measurement points on the minimum bus voltage of the power supply connected to the generator and the high-voltage side bus of the main transformer. Furthermore, existing technologies require continuous manual monitoring of a large amount of test data, resulting in high manpower requirements, dispersed workstations, and difficulties in communication during the testing process. This can negatively impact the monitoring, analysis, and recording of test data, reducing overall testing efficiency. In this embodiment, the input signal terminal 130 is connected to multiple measuring instruments, which are respectively set at various measurement points on the generator in the power plant. This allows for the acquisition of temperatures at multiple measurement points on the generator end core and metal structural components, as well as the minimum bus voltage of the power supply connected to the generator and the voltage at multiple measurement points on the high-voltage side bus of the main transformer. This significantly saves manpower and reduces the impact of human factors on the monitoring, analysis, and recording of test data, thereby reducing the possibility of extended testing periods and errors in test result judgment, and improving testing efficiency.

[0050] refer to Figure 3 Optionally, the main control system also includes a test input module 1504; the output terminal of the test input module 1504 is connected to the second input terminal of the data processing module 1502. The test input module 1504 is used to receive alarm values, termination values ​​and test limit conditions of various operating data of the generator before the generator's leading phase test begins, and send them to the data processing module 1502.

[0051] The data processing module 1502 is also used to issue an alarm command to the output module 1503 when any data in the running data meets the alarm value; the data processing module 1502 is also used to issue a termination command to the output module 1503 when any data in the running data meets the termination value; the data processing module 1502 is also used to issue a demagnetization command to the output module 1503 when all data in the running data fails to meet the test limit conditions; wherein, the control commands include alarm commands, termination commands and demagnetization commands.

[0052] The output module 1503 is also used to issue alarm information according to the alarm command; the output module 1503 is also used to send the termination command to the excitation system of the power plant to control the end of the leading phase test; the output module 1503 is also used to send the demagnetization command to the excitation system of the power plant to control the leading phase depth of the generator.

[0053] The operational data includes phase advance test data and measurement data.

[0054] Specifically, when any data in the operating data meets the alarm value, the data processing module 1502 sends an alarm command to the output module 1503, causing the output module 1503 to issue an alarm message according to the alarm command. When any data in the operating data meets the termination value, the data processing module 1502 also sends a termination command to the output module 1503. The output module 1503 then sends the termination command to the power plant's excitation system, controlling the termination of the generator leading phase test. At this time, the data processing module 1502 can also generate test results, providing real-time, accurate, direct quantitative evaluation and analysis for test personnel, helping them make timely and accurate judgments on the test results, reducing their workload, and improving test efficiency. When none of the data in the operating data meets the test limits, the data processing module 1502 sends a demagnetization command to the output module 1503. The output module 1503 then sends the demagnetization command to the power plant's excitation system, controlling the generator's leading phase depth. This achieves full-process control of data acquisition, data processing, and result analysis during the generator leading phase test, enabling comprehensive online evaluation of the generator leading phase test and improving test efficiency.

[0055] This utility model embodiment can realize the real-time transmission of the measurement point information required for the test. The data processing module 1502 can analyze and compare the input phase advance test data and measurement data with the acceptance standard in real time, and has the functions of data validity judgment and test early warning prompt. The output signal terminal 140 is connected to the generator excitation system interface. When the data processing module 1502 determines that the test termination condition has not been met, the data processing module 1502 can issue a reduction excitation control command to continue to increase the phase advance depth of the generator, realize the whole process management of the phase advance test, and improve the test efficiency.

[0057] Specifically, the main control system 150 implements data storage functionality through a data storage unit 1505. The data storage unit 1505 can receive and store phase advance test data, measurement data, control commands, and test results. The data storage unit 1505 also has an export function, which can export historical phase advance test data, measurement data, control commands, and test results, facilitating test data recording and analysis and providing data reference for subsequent tests.

This allows test personnel to promptly view the data during the generator phase advance test. The display module 160 can also display control commands and test results in real time. Control commands include demagnetization commands of varying magnitudes, and test results include pass and fail. The display module 160 can also display alarm information in real time, such as an alarm message indicating that EC311 has reached the warning value, where EC311 is the corresponding location point in the generator. Finally, the display module 160 can display the phase advance depth of the generator in real time, allowing test personnel to promptly confirm the progress of the generator phase advance test.
