The system disposably carries out complete detection to two tested yaw drives, and hardware capability is tested as shown in figure 3, In
It carries out test comprehensively before, needs to carry out each tested yaw drive failure triggering, when each tested yaw drive is normal, safety
Contact closure (through self-test when detecting that driver is normally in ready state, safety contact is closed driver), hardware makes
Energy input terminal input signal is high level, driver proper testing；When each tested yaw drive failure, safety contact is disconnected,
The input signal that hardware enables input terminal is low level, and tested yaw drive stops working (any tested inclined in test process
Boat driver failure can make two tested yaw drives all stop working), it is ensured that tested yaw drive test process
Safety carries out.
Then, the hardware capability test of tested yaw drive is carried out, hardware capability test specifically includes that CANopen is logical
Telecommunication function (abbreviation communication function), analog acquisition function (referred to as acquisition function), brake circuit control function, motor speed control
Function processed, motor torque control function, brake circuit failure etc..
When carrying out communication function and analog acquisition functional test, tested yaw drive works in ready state:
Acquire the test process of function are as follows:
Tested yaw drive DC bus-bar voltage collection test: the bus voltage value 2 tested yaw drives is (whole
The DC side of stream bridge connects bus) upload to PLC module, PLC module compares 2 tested yaw drive bus voltage values, and two
Person's deviation is then normal less than ± 10V, otherwise abnormal；
Radiator temperature collecting test: the temperature collection value of 2 tested yaw drives is uploaded to PLC module, PLC mould
Block compares 2 tested yaw drive temperature collection values, and the two deviation is less than ± 5 DEG C then normally, otherwise abnormal, controls plate temperature
Acquisition and motor temperature collecting test method are identical as this method, do not do excessive introduction.
The test process of communication function are as follows: when hardware capability test starting, PLC module simultaneously with the first tested driver
CAN communication is executed with the second tested driver, PLC module has feedback showing communication function just when being acquired functional test
Often, otherwise it is abnormal.
Carrying out brake circuit control function, motor speed control function, motor torque control function, brake circuit failure
When test, tested yaw drive works in enabled state:
Under enabled state, first motor is connected with the second motor coaxle to dragging operation, the first tested yaw drive and the
The subsystem work of one motor form is in speed closed loop state, for controlling the revolving speed of entire test macro；Second tested yaw
The subsystem work of driver and the second motor form changes the by controlling the electric current of the second motor in torque closed loop states
The level of torque of two motors, the load for simulating practical yaw motor change, and speed and torque may be implemented in Auto-Test System
Flexible modulation completes the various hardware capability tests of tested yaw drive, under normal circumstances, the nominal drive torque of the second motor
It is worth less than normal than the nominal drive torque value of first motor.
Motor speed control function test process are as follows:
PLC module issues rotating speed command to tested yaw drive, is tested yaw drive rotation and becomes acquisition motor speed value
PLC module is uploaded to, PLC module compares given rotating speed (i.e. rotating speed command) and rotation becomes acquisition tachometer value (actual speed), the two
Deviation is then normal less than ± 20RPM, otherwise abnormal.
Motor torque control function test process are as follows:
PLC module issues torque (electric current) order to tested yaw drive, internal drive current sensor acquisition electricity
Electromechanical flow valuve uploads to PLC, and PLC compares given torque (electric current) and sensor acquires current value, and the two deviation ± 3A is then normal,
Otherwise it is abnormal.
The test process of brake circuit control function are as follows:
PLC module transmitting order to lower levels makes tested yaw drive driving motor become 0rpm from 2000rpm, when motor by
When 2000rpm becomes 0rpm, if brake circuit control hardware circuit does not work, bus overvoltage failure is triggered；When motor by
When 2000rpm becomes 0rpm, if brake circuit control hardware circuit is normal, bus overvoltage failure will not be triggered.
The test process of brake circuit failure are as follows: closure braking resistor wiring, if PLC module detects that tested yaw is driven
Dynamic device brake circuit voltage and DC bus-bar voltage consistent (deviation is less than 5V) are then normal.
It is tested yaw drive under ready state and is unable to translator operation, being tested yaw drive under enabled state can band
Motor operation；Be tested yaw drive in the ready state and issue enabled order, tested yaw drive enter enabled state (
It is operating status), when enabling to cancel, it is tested yaw drive and returns to ready state；The working condition of tested yaw drive
Be divided into standby mode, pre-charge state, ready state, enabled 5 class such as (operation) state and malfunction, ready state with enable
State is two kinds of different working conditions of driver, and therefore, ready state and operating mode under enabled state be not identical.
The Auto-Test System can also carry out load as shown in Figure 4 to each tested yaw drive by host computer and survey
Examination, when carrying out load test, tested yaw drive works in enabled state, first and to two tested yaw drives
Failure triggering is carried out, when fault-free follows the steps below, and two tested yaw drives controls corresponding motor by providing shape respectively
(first motor is connected with the second motor coaxle, and first motor works in motoring condition, can be through speed closed loop control for state operation
System makes first motor work in motoring condition, and the second motor works in generating state, and can be makes the by torque closed-loop control
Two motors work in generating state), while acquiring the motor temperature value, motor speed value and tested yaw drive of corresponding motor
Output current value, and acquire the main analog amount information of tested yaw drive, judge the operation shape of tested yaw drive
Whether state is normal；
When load test starts, first motor drags the second motor operation, and each tested yaw drive will be adopted respectively respectively
Heatsink temperature value, driver temperature value, motor temperature value, driver bus voltage value, motor speed value and the driver of collection
Output current value is uploaded to host computer by CAN communication, and host computer is according to preset normal data；Such as: setting heat dissipation
Device temperature rise value be less than or equal to 40 DEG C it is normal, being tested yaw drive output current value deviation, to be less than 4A normal, by with setting value
It is compared, determines whether every collection value especially radiator temperature rise value, driver output current value be normal；Simultaneously in load
In test process, which discharges the energy of the motor feedback under power generation mode, braking electricity by the way of dynamic braking
Resistance consumes motor feedback energy；Braking resistor causes braking resistor temperature to increase when consuming the feedback energy of motor, braking
Resistance temperature starts cabinet body radiator fan after being increased to certain value, and the operating of cabinet body radiator fan reduces braking resistor temperature rise, protection
Power control cabinet is not because of component in the too high damage braking resistor of braking resistor temperature rise and cabinet.
The Auto-Test System increases integrated control module, carries out the test of hardware capability to yaw drive and load is surveyed
Examination, realizes comprehensive test of yaw drive.
