An embodiment of the invention provides a wind power pitch control method, and referring to fig. 3, fig. 3 is a schematic flow diagram of an embodiment of the wind power pitch control method.
In this embodiment, the wind power pitch control method is used for a wind power pitch control system, the wind power pitch control system includes a wind power pitch assembly, a driver and a controller, and the wind power pitch control method includes the following steps:
and step S100, when the controller receives a control instruction, converting the control instruction into a control signal.
Specifically, when a pitch task needs to be executed, the external control device needs to send a control instruction to the wind power pitch control system. When the controller of the wind power pitch control system receives the control instruction again, the control instruction can be converted into a control signal, and the control signal is sent to the driver so as to control the driver to drive the corresponding wind power pitch assembly to execute a pitch task.
At this moment, the driver and the controller are possibly replaced due to maintenance, damage or part maintenance, and the like, so that the stability and reliability of the wind turbine generator are not high due to different qualities, different safety control logics and different parameter settings of the driver and the controller, and safety accidents of the wind turbine generator are easily caused when wind power pitch control is carried out.
Therefore, when the controller receives the control instruction, the driver is required to judge whether the current controller is matched with the controller, and only when the controller is matched with the driver, the driver can execute the driving action corresponding to the control signal transmitted by the controller, so that the safe and stable operation of the wind turbine generator is ensured.
Step S200, a controller reads an activation registration code of a driver and generates a control registration code according to the activation registration code; and when the activation registration code is integrated with the wind power pitch system, the registration code written in by the external equipment is received by the driver.
Specifically, the controller reads the activation registration code of the drive first, and converts the activation registration code of the drive into the control registration code, so that the control registration code is processed and confirmed by the drive and the controller, and further, when the subsequent drive matches according to the control registration code, data processed and confirmed by the controller can be acquired.
The activation registration code is an activation registration code that a system integrator writes into a drive using an external device when the drive, a controller, or the like needs to be replaced for maintenance, or assembly of the system.
It is easy to understand that when equipment of the wind power pitch system is generated and developed, a system developer needs to obtain a hardware serial number of a driver, call a preset first encryption algorithm, process the hardware serial number, and obtain an activation registration code of the driver. The activation registration code will be sent from the system developer to the system integrator so that the system integrator writes the activation registration code into the drive when the drive is replaced.
Preferably, the hardware serial number is a serial number recorded by a motion control layer or a nameplate of the driver.
In this embodiment, after the activation registration code of the drive is read, the activation registration code may be processed by the controller invoking a preset second encryption algorithm to obtain a control registration code of the drive.
Step S300, the controller sends the control signal and the control registration code to a driver so that the driver can judge whether the controller is matched with the driver according to the control registration code and the hardware serial number of the driver; if so, the driver drives the wind power pitch-variable assembly to execute pitch-variable action according to the control signal, otherwise, an operation alarm signal is generated.
Specifically, after the controller converts the activation registration code into the control registration code, the control signal is transmitted to the driver together with the control registration code, and the driver determines whether the controller matches the control registration code.
In this embodiment, whether the controller is a controller matched with the driver is judged, and the driver calls a preset third encryption algorithm to process the control registration code and the hardware serial number to obtain verification data of the control registration code; after that, the flag bit that the check passed is extracted, and whether the controller is a matched driver is judged.
The third encryption algorithm is generated by the first encryption algorithm and the second encryption algorithm, and the flag bit comparison is carried out on the processing result of the control registration code and the hardware serial number through the third encryption algorithm, so that the matching process of the driver and the controller can be realized.
After the driver is matched, whether to operate the control signal transmitted by the controller is determined according to a matching result; if the matching is successful, the current controller is matched with the driver, the driver drives the wind power variable pitch assembly to execute the variable pitch action according to the control signal, and otherwise, an operation alarm signal is generated.
In the embodiment, a wind power pitch control method is provided, wherein when a controller receives a control instruction, a control registration code is generated according to an activation registration code pre-written by a driver, and whether the current controller is matched with the driver is judged by using the control registration code and a hardware serial number, so that the operation of a wind power pitch system is controlled, and the safety and the power generation performance of the whole wind turbine generator are ensured.
In order to more clearly illustrate the scheme of the application, a specific example of a wind power pitch control method is provided below.
The embodiment provides an encryption protection method for a wind power variable pitch control system, and the technical scheme of the method is as follows:
1) a unique hardware-based serial number is added to a motion control layer and a nameplate of a variable pitch system driver, and the serial number is accumulated according to production and delivery.
2) As shown in fig. 4, a system developer calls an encryption algorithm a according to a serial number of a driver, calculates a registration code 1, and returns the registration code to a variable pitch system integrator; the encryption algorithm A is the own algorithm of a system developer, and the registration code 1 is the activation registration code of the driver hardware;
3) manually writing the registration code 1 into a processor of the driver by a variable pitch system integrator through external equipment, wherein the registration code 1 can be kept memorized when the driver is powered off;
4) as shown in fig. 5, the PLC controller can obtain a registration code 1 from the driver, and the PLC calls an encryption algorithm B based on the registration code 1 to calculate a registration code 2; the registration code 2 is sent to the driver motion control layer; the PLC controller is a controller which is not limited in the master control, the variable pitch or the driver of the wind generating set; the registration code 2 is a control registration code of the controller.
5) As shown in fig. 6, the motion control layer of the drive calls an internally encapsulated encryption algorithm C based on the serial number, checks whether the registration code 2 is correct, and outputs a flag bit indicating whether the check is passed; if the verification is passed, the driver is allowed to transmit the communication data, and the driver can normally operate; otherwise, alarming and prohibiting transmission of communication data. The encryption algorithm C is generated by algorithms a and B.
In this embodiment, a specific example of an encryption algorithm a, an encryption algorithm B, and an encryption algorithm C is also provided.
Description of the definitions: a. d is a specific character; b. p, q, b ', p', q ', e, l, m, e', l 'and m' are intermediate quantities of registration codes; c and c 'are activation registration codes, and f' are control registration codes; the initial values of n, n ', r and r' are 0; u, v, w, z are specific constants; <isbinary left shift; > > is a binary right shift;
as shown in fig. 7, the encryption algorithm a may specifically include the following steps:
(1) adding specific characters to the serial number of the driver hardware, and calculating through an ASCII code inside to obtain b;
(2) a first circulation: activating an initial value of a registration code c as a constant, wherein the c obtains p by shifting u bit to the left in a binary system, obtains q by shifting v bit to the right, and obtains a value c1 of a first cycle by carrying out XOR operation on the initial value c0 and the sum of p and q;
(3) t is the character length of b, and the final activation registration code c is obtained through t times of circular operation.
