[0039] The embodiment of the present application provides a method for testing the synchronous stability of a wind farm based on hardware-in-the-loop simulation, comprising:
[0040] S01, obtaining parameters of various components of the wind turbine set set in the simulation model software, and generating an initial wind turbine model according to the parameters of various components of the wind turbine set;
[0041] In this embodiment, the wind turbine modeling is performed by using GHBladed simulation software and linearization is performed on it, so as to obtain a high-accuracy high-order model of the controlled object. GHBladed simulation software includes a main module, a simulation module, a linearization module and a controller test module; these modules provide users with functions such as steady-state calculation, display result data, modal analysis, linearization model generation, and external controller simulation interface. The software provides a series of parameter settings for each component of the wind turbine to generate an initial wind turbine model.
[0042] S02, inputting the operation control instructions simulating the operation conditions of the power grid into the initial wind turbine model of the simulation model software to generate a wind turbine model that can be used for control system simulation test;
[0043] The step of inputting the operation control instructions simulating the operation conditions of the power grid into the initial wind turbine model of the simulation model software to generate a wind turbine model that can be used for the control system simulation test comprises:
[0044] Step S21, inputting the operation control instructions simulating the grid operation condition into the initial wind turbine model of the simulation model software;
[0045] The control instructions of external power grid faults or other working conditions are input into the relevant modules of the GHBladed simulation software.
[0046] The operation control instructions for simulating the operation conditions of the power grid include operation control instructions for simulating the normal operation state of the power grid, operation control instructions for simulating the abnormal operation state of the power grid, and operation control instructions for simulating the fault state of the power grid. The simulated fault state of the power grid supports multiple fault simulations (such as low voltage ride-through, high voltage ride-through, etc.). By simulating different power grid operation conditions, the simulation experiment process simulates different power grid operation conditions, and further ensures the stability of the wind farm.
[0047] Step S22, the simulation model software sets the corresponding operating parameter values of the initial wind turbine model according to the operating control instruction, and generates a linearized data model corresponding to the operating condition;
[0048] By setting the parameters of the wind turbine in the relevant modules of the GHBladed simulation software, after obtaining the simulation model of the unit, the operating wind conditions are set to obtain the operating parameter values of the unit under the wind conditions, so as to achieve the purpose of operation simulation. The linearized data model is generated by using the operating point set by the model linearization module of the GHBladed simulation software.
[0049] Step S23: Process the linearized data model to obtain linearized model data, and generate a wind turbine model that can be used for control system simulation test according to the linearized model data.
[0050] The linearized data model is processed by LinarModel and output as MIMO linearized model data (*mat). This data file is directly compatible with MATLAB software, and can be processed and used to generate a wind turbine model that can be used for control system simulation testing.
[0051] The wind turbine model can simulate the operating status of an actual wind turbine and ensure the synchronous operation of the wind turbine under different power grid conditions by controlling the output power and speed of the wind turbine in real time.
[0052] S03, inputting the strategy control instruction required to verify the synchronization stability into the wind turbine model;
[0053] By setting different control strategies to conduct more realistic and effective simulation experiments, the stable operation capability of the wind farm and the synchronous stable operation capability of the wind farm can be verified.
[0054] S04, performing simulation test on the wind turbine model based on a hardware-in-the-loop simulation platform, and outputting simulation results;
[0055] By setting different control strategies under different grid operating conditions to conduct more realistic and effective simulation experiments, and conducting simulation tests based on a hardware-in-the-loop simulation platform, the simulation results can provide test data for subsequent wind farm stability assessments.
[0056] Specifically, the wind turbine model is simulated and tested based on the hardware-in-the-loop simulation platform, and the output simulation results include:
[0057] The hardware-in-the-loop simulation platform reads the operating parameters of the current simulated power grid operation of the wind turbine model;
[0058] The hardware-in-the-loop simulation platform transmits the wind turbine control instructions output by the PLC to the wind turbine model according to the operating parameters, controls the wind turbine model to perform simulation operation, and outputs simulation results.
[0059] S05. Process and analyze the simulation results to evaluate the control strategy effect and operating status of the wind farm under different power grid operations.
[0060] By setting different control strategies under different grid operating conditions to conduct simulation tests on wind farm stability, based on real-time data and analysis under operating conditions, and evaluating the effects of wind farm control strategies and operating status, the synchronous stability and reliability of wind farms under various grid conditions are ensured.
[0061] It should be noted that the wind turbine model includes a wind model, an aerodynamic model, a mechanical model and an electromagnetic transient model. A wind turbine is a device that integrates mechanical, electrical and control systems to achieve the conversion of wind energy into electrical energy. It is usually composed of a pneumatic system, a pitch system, a transmission system, an electrical system and a control system.
[0062] The aerodynamic model corresponds to the aerodynamic system, which refers to the mechanism for capturing wind energy in a wind turbine, mainly composed of a hub, blades, a variable pitch mechanism, etc. Its main function is to absorb kinetic energy from the air by reducing the air velocity flowing through the wind wheel, thereby converting wind energy into mechanical energy. In actual operation, due to the variability of air fluid in three-dimensional space, the interaction with the blades produces complex aerodynamic characteristics, so the wind energy capture process is essentially nonlinear.
[0063] The wind model corresponds to the variable pitch system, which refers to the servo mechanism used for adjusting the pitch of the blades in the pneumatic system. Modern large wind turbines are all designed with variable pitch systems, which can control the pitch angle of the blades to change the angle of attack of the incoming wind on the blades, thereby changing the wind energy utilization coefficient. At low wind speeds, the tip speed ratio is kept at the optimal value by changing the pitch angle to achieve maximum capture of wind energy; at high wind speeds, the current wind energy utilization coefficient is adjusted by changing the pitch angle to keep the power output at the rated value.
[0064] The mechanical model corresponds to the transmission system, which refers to the mechanical transmission mechanism connecting the pneumatic system and the electrical system, mainly including gearboxes, couplings and connecting shafts. It is mainly responsible for transmitting the mechanical energy of the wind wheel in the pneumatic system to the generator in the electrical system. During operation, the balance of mechanical torque and the stability of speed are achieved by controlling the balance of the rotational mechanical energy of the inertia source at both ends of the transmission system. The transmission system has a significant impact on the dynamic characteristics of the unit operation process.
[0065] The electromagnetic transient model corresponds to the electrical system. The electrical system refers to the mechanism in the wind turbine that realizes the conversion of rotating mechanical energy into electrical energy, mainly including generators, rectifier inverters and transformers. Large wind turbines are connected to the power grid through the electrical system. It is mainly responsible for the conversion and transmission of electrical energy. After converting the mechanical energy of the transmission system into electrical energy, the rotor and stator of the double-fed asynchronous generator are connected to the power grid through rectifier inverters and transformers for power transmission. Most modern large wind turbines adopt variable speed constant frequency design. Among them, the widely used double-fed asynchronous generator realizes the variable speed function by controlling and adjusting the electromagnetic torque of the generator to change the speed of the rotor.
[0066] As a logical system of the entire wind turbine model, the control system is a controlled object in the hardware-in-the-loop simulation process, mainly including wind power generation process control and wind turbine protection control. It improves operating efficiency and ensures the safe operation of wind turbines by controlling the speed, pitch angle, torque and other states. With the improvement of wind power technology, the unit capacity is gradually increasing, and the requirements for control systems are getting higher and higher. The superiority of modern variable pitch wind turbines in capturing wind energy also requires the support of a good control system to be reflected.
[0067] A wind farm synchronization stability test method based on hardware-in-the-loop simulation of the present invention obtains the parameters of each component of the wind turbine set set in the simulation model software, and generates an initial wind turbine model according to the parameters of each component of the wind turbine set; inputs the operation control instructions simulating the operation conditions of the power grid into the initial wind turbine model of the simulation model software, and generates a wind turbine model that can be used for control system simulation test; inputs the strategy control instructions that need to verify the synchronization stability into the wind turbine model; performs simulation test on the wind turbine model based on the hardware-in-the-loop simulation platform, and outputs the simulation results; processes and analyzes the simulation results, and evaluates the control strategy effect and operation status of the wind farm under different power grid operations. The present invention can fully simulate the actual operation of a complex power grid, and verify the stable operation capability of the wind farm and the synchronous stable operation capability of the wind farm by simulating different operation conditions of the power grid. At the same time, the hardware-in-the-loop (HIL) simulation technology is adopted to provide a high-precision, low-latency test environment to ensure the stable operation capability of the wind farm under complex power grid conditions.
[0068] In a preferred implementation manner of the present application, a method for testing wind farm synchronization stability based on hardware-in-the-loop simulation further includes:
[0069] According to the control strategy effect and operating status of the wind farm under different power grid operations, the strategy control instruction is modified, and the modified strategy control instruction that needs to verify the synchronization stability is input into the wind turbine model, and steps S04 to S05 are repeated.
[0070] In this embodiment, the control strategy is continuously optimized and modified according to the effect of the control strategy, the stable operation capability of the wind farm and the synchronous stable operation capability of the wind farm are verified, and the synchronous stability of the wind farm under complex power grid conditions is ensured.
[0071] In another embodiment of the present application, a method for testing the synchronous stability of a wind farm based on hardware-in-the-loop simulation is as follows:
[0072] The GHBladed simulation software provides a series of parameter setting interfaces for various wind turbine components for model building. The wind turbine model is generated by setting the overall characteristics of the wind turbine blades, blade aerodynamic characteristics, basic parameters of the hub and wind rotor system, detailed parameters of the tower, transmission chain related parameters, nacelle parameters, control methods and other parameters from left to right.
[0073] By setting the parameters of the wind turbine in the relevant modules, the simulation model of the unit is obtained, and then the operating wind conditions are set to obtain the operating parameter values of the unit under the wind conditions, so as to achieve the purpose of operation simulation. The linearized data model is generated by using the operating point set by the model linearization module of the GHBladed simulation software, and the linearized data model is processed and output as MIMO linearized model data (*mat) through LinarModel. This data file is directly compatible with MATLAB software, and MATLAB software can be used to process it and generate a model that can be used for control system simulation test.
[0074] A set of linear state space models under wind speed generated by GHBladed simulation software is:
[0075]
[0076] Where x is the system state vector; u is the input vector; y is the output vector; A, B, C, D state space coefficient matrix;
[0077] In the post-processing module of GHBladed simulation software, various detailed unit parameters can be selected as input and output parameters of the state space model. In this embodiment, the following input and output parameters are selected through analysis of the design purpose and function of the controller:
[0078] u=(V w , β d , T E,d )
[0079] Where V w is wind speed; d is the pitch angle requirement; T E,d is the generator torque requirement;
[0080]
[0081] In the formula, ω g is the measured value of the generator speed; T E is the actual value of the generator electromagnetic torque; P E is the power measurement value.
[0082] At this point, the structure is the linearized model matrix of the specific controlled object of the wind turbine under a set of wind speeds. The matrix is a (*.mat) file. By processing the matrix of the (*.mat) file, it is directly compatible with MATLAB software. MATLAB software can be used to process it and generate a wind turbine model that can be used for control system simulation experiments.
