In addition, descriptions of features known in the art may be omitted for clarity and brevity.

[0028] The embodiments described in the following embodiments of the present invention do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0029] Conventional excitation systems can only process one output signal of the generator in a targeted manner. For power generation equipment such as three-winding generators, since they have at least two outputs, multiple outputs may affect each other. Therefore, a mechanism for output management of multi-output power supply systems is urgently needed.

[0030] In order to solve the above problems, the embodiments of the present invention provide a generator output control method, device and system. The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] An exemplary embodiment of the present invention provides a generator output control device, the structure of which is as follows: Figure 1 As shown, including: A processing chip 101, at least two analog signal processing modules 102 and an analog output interface 103, wherein the processing chip 101 is connected to a load 104 connected to at least one output of a generator through the analog output interface 103; Each of the analog signal processing modules 102 is respectively connected to one output of the generator, and is used to collect and send the voltage signal and / or current signal of each output of the generator to the processing chip 101; The processing chip 101 is used to receive the voltage signal and / or current signal sent by the analog signal processing module 102, generate and send a load control signal to the analog output interface 103; The analog output interface 103 is used to adjust the size of the load 104 connected to the output of the generator according to the load control signal sent by the processing chip 101 .

[0032] The processing chip 101 may specifically be a digital signal processing (DSP) chip or a DSP microcomputer board.

[0033] The above generator output control device can be used as an independent device or apparatus, or can be integrated into an excitation regulator or excitation system for controlling the operation of the generator, and the excitation regulator or excitation system realizes the corresponding functions. Among them, the processing chip 101 can be realized by the processing module of the excitation regulator, and a corresponding number of analog signal processing modules 102 are configured in the excitation regulator or excitation system according to the application scenario, and an analog output interface 103 is added. The excitation regulator can be a component of the excitation system, which is used to control the power unit to provide excitation current for the generator rotor according to the input signal and the given regulation rule.

[0034] According to an exemplary embodiment, the analog signal processing module 102 includes at least one or more of the following elements: Measuring voltage transformers, instrument voltage transformers, current sensors.

[0035] Among them, the measuring voltage transformer (also referred to as measuring PT) and / or the instrument voltage transformer (also referred to as instrument PT) are used to detect the voltage signal output by the generator. The current sensor (also referred to as CT) is used to detect the current signal output by the generator.

[0036] According to an exemplary embodiment, the generator output control device is applied to a generator having two outputs, including a first output and a second output, wherein the generator may be a three-winding generator.

[0037] The second output is connected to the adjustable load cabinet to provide electrical energy to the adjustable load cabinet.

[0038] The analog output interface 103 is connected to the adjustable load cabinet and is used to adjust the load size of the adjustable load cabinet according to the load control signal sent by the processing chip.

[0039] The adjustable load cabinet (or adjustable load box) can be used as a simulated load for generators, engines, etc. to detect the performance of generators or engines. The load size provided by the adjustable load cabinet is adjustable and can be changed according to actual application requirements. The load provided by the adjustable load cabinet can be purely resistive, or an inductive load in parallel with an inductor, or a capacitive load in parallel with a capacitor.

[0040] According to an exemplary embodiment, when the generator output control device is integrated into an excitation regulator or an excitation system, two sets of pseudo signal processing modules 102 may be configured in the excitation regulator or the excitation system to monitor and control a generator system with dual outputs (e.g., a three-winding generator with dual outputs).

[0041] An exemplary embodiment of the present invention further provides a generator output control system, the structure of which is as follows: Figure 2 As shown, including: Generator 201, such as Figure 1 The generator output control device 202 and the adjustable load cabinet 203 are shown; the generator has at least two outputs, one of which is connected to the adjustable load cabinet, and the generator output control device 202 is electrically connected to the adjustable load cabinet; The generator output control device 202 is used to collect voltage signals and / or current signals of various outputs of the generator 201 and generate a load control signal to adjust the load size of the adjustable load cabinet 203 .

[0042] The generator output control device 202 may be integrated into an excitation regulator or an excitation system, and the excitation regulator or the excitation system may realize corresponding functions.

[0043] An exemplary embodiment of the present invention further provides a generator output control system, the structure of which is as follows: Figure 3 As shown, it includes: a generator, an excitation system and an adjustable load cabinet.

[0044] The generator has two outputs, one output is connected to the load and the other output is connected to the adjustable load cabinet.

[0045] The excitation system includes a power unit and an excitation regulator.

[0046] The power unit can be realized by a power demagnetization cabinet, which also includes an excitation circuit and a demagnetization part.

[0047] The excitation regulator includes two AC signal processing modules (as analog signal processing modules), DSP microcomputer board (as processing chip), analog input and output module (providing analog output interface), switch input and output module, pulse output module, DC signal processing module and power supply. It can provide users with a visual operation interface, through which users can send instructions to the DSP microcomputer board.

[0048] The two AC signal processing modules respectively collect the two outputs, specifically, including CT, measurement PT, and instrument PT. The voltage signals and / or current signals of the two outputs collected by the AC signal processing module are transmitted to the DSP microcomputer board.

[0049] The DSP microcomputer board controls the power unit by adjusting the pulse output interface to adjust the excitation voltage, thereby controlling the excitation of the generator.

[0050] An exemplary embodiment of the present invention further provides a generator output control method, which is applicable to the generator output control device and generator output control system provided in the embodiments of the present invention. The process of using this method to adjust the generator output by adjusting the adjustable load cabinet is as follows: Figure 4 As shown, including: Step 401: Collect voltage signals and / or current signals output from each channel of the generator.

[0051] In this step, the voltage signal and / or current signal of each output is obtained respectively through the analog signal processing module.

[0052] According to an exemplary embodiment, the voltage signal and / or the current signal may be acquired by measuring PTs, instruments PTs, and CTs.

[0053] This step can be performed in response to instructions, such as performing detection and collection when receiving a detection instruction issued by the control platform or an operator; it can also be performed in real time and continuously, for example, when the generator is working, the collection cycle is set to 1 second and collection is performed once per second.

[0054] Step 402: Acquire the operating condition of the generator according to the voltage signal and / or the current signal.

[0055] According to an exemplary embodiment, the generator has a first output and a second output, and the second output is connected to a load of adjustable size, specifically, connected to an adjustable load cabinet.

[0056] This step is as follows Figure 5 As shown, including: Step 501: Determine the current output voltage and / or output power of the first output and / or the second output according to the voltage signal and / or the current signal.

[0057] In this step, the output voltage of the corresponding output can be determined according to the detected voltage signal.

[0058] According to the voltage signal and the current signal, the output power of a corresponding output can be determined.

[0059] By measuring the output voltage and output power of each output, the power supply status and total output power of the generator can be understood.

[0060] This step can calculate the output power once each time the voltage signal and / or current signal is collected; a detection cycle can also be preset, and when each detection cycle arrives, the calculation is performed based on the data obtained from the last collection before the current moment. The detection cycle and the collection cycle of the voltage signal and / or current signal can be different; it can also be performed in response to instructions from the control platform.

[0061] Step 502: Determine the operating condition of the generator.

[0062] In this step, when at least any one of the following conditions is met, it is determined that the operating condition of the generator is in a state to be optimized: The output voltage of the first output and / or the second output exceeds a preset rated voltage deviation range, The output power of the first output and / or the second output exceeds a preset rated power deviation range.

[0063] For example, the rated voltage value is preset to be 380V, and the rated voltage deviation range is 10% above and below 380V. If the output voltage of any output exceeds the rated voltage deviation range, the working state of the generator may be abnormal and needs to be adjusted, and it is determined to be in a state to be optimized.

[0064] The rated power value can also be preset, and this parameter can be set according to the rated power value when the generator is designed. Within the rated power range (taking the rated power value as 200kW as an example, when the output power is less than 200kW, it is determined that the generator is working within the rated power range), the output can be normal; if it exceeds the rated power, the output of the generator needs to be adjusted.

[0065] When detecting the output power, the output power of each output can be detected separately. When the output power of any output exceeds the rated power range, the working state of the generator may be abnormal and is determined to be in a state to be optimized.

[0066] Step 403: According to the working condition of the generator, adjust the size of the load connected to the output of the generator.

[0067] In this step, since the working condition of the generator indicates that the generator is in a state to be optimized, the output of the generator needs to be adjusted. According to one embodiment, the overall output of the generator can be adjusted by adjusting the size of the load connected to the second output. The specific process is as follows: Figure 6 As shown, including: Step 601: Calculate a target load when the working condition of the generator indicates that the generator is in a state to be optimized.

[0068] In this step, the target load is calculated based on the currently acquired output voltage and rated voltage value of the first output and the second output, and / or the output power and rated power value of the first output and the second output.

[0069] According to an exemplary embodiment, the load size required to be loaded on the second output may be calculated through PI regulation as the target load.

[0070] When the sum of the output powers of the two outputs is higher than the upper limit of the rated power deviation range, it is necessary to increase the size of the load connected to the second output to reduce the output power and ensure that the generator operates within a safe range.

[0071] Step 602: Send a load control signal to instruct to adjust the size of the second output access load according to the target load.

[0072] In this step, after determining the target load, the adjustment plan is determined, and then a load control signal can be sent to the adjustable load cabinet through the analog output interface to instruct the adjustable load cabinet to adjust the size of the load connected to the second output according to the target load.

[0073] If the output voltage and output power of both outputs do not exceed the preset range, the excitation system can continue to output the excitation voltage normally to control the generator output voltage without adjusting the size of the load connected to the second output.

[0074] By real-time monitoring of the two outputs, the working condition of the generator is judged, and the load size connected to the second output is adjusted accordingly. The balance between the first output and the second output is achieved by automatically adjusting the load size, ensuring the efficient output of the generator while ensuring the safety of the generator operation.

[0075] An exemplary embodiment of the present invention further provides a generator output control device, the structure of which is as follows: Figure 7 As shown, including: The signal acquisition module 701 is used to acquire voltage signals and / or current signals outputted from various channels of the generator.

[0076] The operating condition analysis module 702 is used to obtain the operating condition of the generator according to the voltage signal and / or the current signal.

[0077] The load adjustment module 703 is used to adjust the size of the load connected to the output of the generator according to the working condition of the generator.

[0078] Furthermore, the generator has a first output and a second output, the second output is connected to a load with an adjustable size, and the structure of the working condition analysis module 702 is as follows: Figure 8 As shown, including: A signal analysis submodule 801 is used to determine the current output voltage and / or output power of the first output and / or the second output according to the voltage signal and / or the current signal; The operating condition determination submodule 802 is used to determine whether the operating condition of the generator is in a state to be optimized when at least any of the following conditions is met: The output voltage of the first output and / or the second output exceeds a preset rated voltage deviation range, The output power of the first output and / or the second output exceeds a preset rated power deviation range.

[0079] Furthermore, the structure of the load adjustment module 703 is as follows: Fig. 9 As shown, including: A target load calculation submodule 901 is used to calculate a target load when the working condition of the generator indicates that the generator is in a state to be optimized; The signal sending submodule 902 is used to send a load control signal to instruct to adjust the size of the second output access load according to the target load.
