Description
5460-836 WOODWARD 2301A Speed Control Controller
Non differential regulation is mainly used for constant speed control and is suitable for single machine operation or multiple prime movers working together in an isolated power grid. Differential regulation provides more control flexibility.
further enhancing its performance and application range.
rich additional functions, and high-precision output signals. Whether it is in the fields of generator sets, compressors, pump stations, or ships and locomotives, it can effectively ensure the stable operation of equipment within the set range.
power measurement level 1, editable screen, multi interface toolkit connection, etc. All details can be found in Woodward easyYgen manual 37582A
The rated operating temperature range of this model is -20 to 70 ° C; the rated temperature range of the LT model is -40 to 70 ° C, suitable for outdoor use.
5460-836 is equipped with a monitor (not available on the 3100 model) and is designed for front panel installation.
The built-in HMI has a color LCD and soft keys (now with dedicated buttons) for direct control of the 5460-836 device. Multi level password protection can prevent unauthorized changes.
The generator set has four operating modes and the option to configure a manual circuit breaker control device.

2. Principle of frequency converterIn embedded development, the control of motors is often involved. Currently, frequency conversion control of AC motors is widely used, so let”s briefly introduce the frequency converter by looking at the diagram, assuming that you already understand the principle of the motor.The block diagram is as follows:The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, microprocessing unit, etc. The inverter relies on the switching of the internal IGBT to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter also has many protection functions. , such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used.A typical inverter system diagram is shown below. It mainly includes operation panel, VFD controller, motor and other parts.1. Typical structure:Mainly includes: control platform, measurement circuit, power circuit, protection circuit, etc.There are two common types of frequency converters: voltage type and current type. Among them, the power inverter part mostly uses power tubes such as IGBT and IGCT.2. Typical algorithm:Among them, the control algorithm represented by Siemens is mainly based on coordinate transformation (vector control). Friends who are interested in the algorithm represented by ABB can search for information by themselves (direct torque control) and will not go into details here.3. Vector control:Many chip MCU and MPU manufacturers have provided block diagrams and algorithm libraries for variable frequency vector control. Those who are interested can study it. For example, the following figure is a block diagram provided by Microchip
