Description

[0002] With the increasing demand for clean energy worldwide, wind power, as a renewable and pollution-free energy source, has rapidly developed, and the number and scale of wind turbine generators have continuously expanded, with increasingly high requirements for their reliability and stability. As one of the key components of a wind turbine generator, a variable pitch system directly affects the performance and safety of the generator.

[0003] Since wind turbine generators are usually installed in remote areas with harsh environments, the components of the variable pitch system of the wind turbine generator often wear out, fail or break down during long-term operation, which makes maintenance difficult. Without timely spare parts repair and testing, this may result in extended downtime of the generator, affecting power generation efficiency, and even endangering the safety of the generator. Currently, technical identification of old spare parts can only be carried out through measurement, but this process cannot determine the state of the spare parts when they are live. For spare parts repaired by maintenance companies, they can only be installed and tested on the wind turbine generator to determine whether they have been completely repaired. At the same time, different scales and different scenarios of wind turbine generators have different corresponding variable pitch systems and components, which further increases the difficulty of maintenance.

DETAILED DESCRIPTION

[0027] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features; in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0029] At present, with the increase of the operation time of the wind turbine generator, the spare parts of the variable pitch system often appear wear and failure, and at the same time, due to the skill level of the maintenance personnel, a part of good spare parts are replaced from the wind turbine generator as bad spare parts, causing waste. The existing technical identification for old spare parts can only be carried out by measuring, and the process cannot determine the state of the spare part when it is live, and the spare part repaired by the repair factory can only be installed and tested on the wind turbine generator to know whether it is completely repaired. On the other hand, due to the uneven repair level of the spare part repair factory, many faulty spare parts are not completely repaired in actual application, which makes the repaired spare parts cause longer downtime after being installed on the wind turbine generator, thereby causing huge workload of the on-site personnel and increasing the downtime of the wind turbine.

[0030] At the same time, for wind turbine generators of different scales and different scenes, the corresponding variable pitch systems and components thereof are also different, such as the four brands of direct current variable pitch systems commonly used in the field, which cannot realize compatibility of the spare part test environment, which further increases the difficulty of maintaining the variable pitch system.

[0031] To solve the above technical problems, the present application proposes the following technical solutions and corresponding embodiments.

[0032] Embodiment 1

[0033] The technical scheme of the present application will be described below in combination with the embodiments shown in the drawings: Figures 1 to 5

[0034] Figure 1 The structure schematic diagram of the variable pitch system spare part compatibility test system according to the embodiments of the present application is shown in FIG. 1, which shows a variable pitch system spare part compatibility test system according to the embodiments of the present application. Figure 1 ​As shown, the spare part compatibility test system 100 of the embodiment of the application comprises: an upper computer module 101, a variable pitch motor module 103, a first test module 1021 and a second test module 1022; the first test module 1021 and the second test module 1022 are respectively electrically connected with the upper computer module 101 and the variable pitch motor module 103; the upper computer module 101 is configured to determine a target test module based on a target variable pitch system corresponding to a spare part to be tested, and to supply power to the target test module; the target test module is the first test module 1021 or the second test module 1022; wherein the first test module 1021 is configured to test a first variable pitch system based on a variable pitch controller in a case where the variable pitch motor module 103 is an internal speed measuring generator; and the second test module 1022 is configured to test a second variable pitch system based on the variable pitch controller in a case where the variable pitch motor module 103 is an external rotary transformer.

[0035] In the embodiment of the application, the target variable pitch system is a faulty variable pitch system on a wind turbine generator set to which the spare part to be tested belongs. Since the components of variable pitch systems of different brands (imported / indigenous) are different, the target variable pitch system can be understood as a variable pitch system of the same manufacturer / brand. The test components of the target test module correspond to the target variable pitch system.

[0036] In the embodiment of the application, the upper computer module 101 comprises upper computer software and a monitoring device, wherein the upper computer software can be installed on a PC as the monitoring device.

[0037] In the embodiment of the application, the variable pitch system spare part compatibility test system 100 adjusts the blades of the wind turbine generator set through the variable pitch motor module 103, which comprises a variable pitch motor, a torque measuring instrument and an eddy current brake. The shaft end of the variable pitch motor is connected with the input end of the torque measuring instrument, and the output end of the torque measuring instrument is connected with the eddy current brake. The variable pitch motor is controlled to rotate by the target test module, and the eddy current brake provides a reverse adjustable braking force for the variable pitch motor, so that the variable pitch system corresponding to the target test module is adjusted from zero load to rated load during the spare part test.

[0038] In the embodiment of the application, the first test module 1021 and the second test module 1022 are two different test modules of the variable pitch system spare part compatibility test system. Through the triggering of the upper computer module 101, the test system can be controlled to enter the corresponding test module. Referring to Figure 2As shown, when the first test module 1021 is used to carry out the test, the first driver power supply switch 11 is closed, the first DC power supply 14 provides power for the first controller 13, the brake contactor 3 is controlled to be closed by the first controller 13, the first driver 12 is controlled to output to provide the torque of the pitch motor 4, wherein the brake torque is provided by the brake 5 (corresponding to the eddy current brake in the embodiment of the application) during the test, the encoder 6 feeds back the speed and position of the pitch motor 4 to the first controller 13, and the torque measuring instrument (corresponding to the torque measurement in the embodiment of the application) measures and displays the real-time torque value of the pitch motor 4 in real time through the torque sensor. Similarly, when the second test module 1022 is used to carry out the test, the second driver power supply switch 21 is closed, the brake contactor 3 is controlled to be closed by the second controller 23, the second driver 22 is controlled to output to provide the torque of the pitch motor 4, and the brake torque is provided by the brake 5 of the pitch motor module during the test. The encoder 6 feeds back the speed and position of the pitch motor 4 to the second controller 23, and the torque measuring instrument measures and displays the real-time torque value of the pitch motor 4 in real time through the torque sensor. The 3-phase 380V AC power supply 1 provides 380V AC power supply for the first driver 12 and the second driver 22 through the first driver power supply switch 11 and the second driver power supply switch 21 respectively. The 3-phase 380V AC power supply 1 provides power for the pitch motor 4 when the brake is opened after being converted into 200V DC through the brake power supply 2 and the brake contactor 3. In the embodiment of the application, the first test module 1021 and the second test module 1022 can be used to test different pitch systems respectively. Here, different pitch systems can be understood as different component types of pitch systems, such as imported brand SSB and domestic brand Dongfang Automatic Control. It should be noted that the types of test modules in the test system of the embodiment of the application are not limited to the above two types.

[0039] Exemplarily, with reference to Figure 3As shown, the first variable pitch system corresponding to the test of the first test module 1021 includes a variable pitch motor with a built-in speed measuring generator, a variable pitch controller based on a programmable logic controller (PLC), and a matching servo driver based on speed measurement of the speed measuring generator. The second variable pitch system corresponding to the test of the second test module 1022 includes a variable pitch motor with an external rotary transformer on the motor shaft, a variable pitch controller based on a single-chip microcomputer, and a matching servo driver based on speed measurement of the rotary transformer. After the host computer module 101 determines the first test module 1021 / second test module 1022 based on the target variable pitch system corresponding to the spare part to be tested, the first test module 1021 / second test module 1022 is powered, and the spare part test is started. The first variable pitch system can also be in the form of a variable pitch motor with a built-in speed measuring generator, a variable pitch controller based on a single-chip microcomputer, and a matching servo driver based on speed measurement of the speed measuring generator. The variable pitch motor of the second variable pitch system can be a series excited direct current motor or a permanent magnet direct current motor.

[0040] The variable pitch system spare part compatible test system provided in the application can quickly provide a test module corresponding to a variable pitch system when testing spare parts of different types of variable pitch systems, greatly improving the compatibility of the ground spare part test system and reducing test time and cost. In addition, the variable pitch system spare part compatible test system of the application can quickly locate the fault source of the spare part by adapting to different components of the variable pitch system, making problem troubleshooting more accurate and improving troubleshooting efficiency.
