8256-016 Details:

 

 

The WOODWARD 8256-016 speed controller has a series of significant product features that make it an ideal choice for engine or generator speed control in industrial applications. The following are its main characteristics:

 

Wide application range: This speed controller can be used in diesel engines, gas engines, steam turbines, or gas turbines, with a wide range of applicability.

Flexible signal input: This controller can set the speed or load of the device based on computer control signals of 4-20mA or 1-5 Vdc, providing users with multiple options to meet different control needs.

Multiple working modes: This controller has two working modes: zero difference adjustment and differential adjustment.
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.

Highly integrated: This speed controller can be used in conjunction with a range of Woodward devices, such as power automatic transferors, input-output controllers, generator load controllers, etc., to achieve more comprehensive system control.

Rich additional functions: In addition to basic speed or load control functions, the controller also has functions such as synchronous or deceleration control, high and low speed adjustment, and fuel limit for override start,
further enhancing its performance and application range.

High precision output signal: The output signal provided by the controller is proportional to the fuel setting required to achieve the desired speed/load, ensuring precise control.

Durable and sturdy: The design takes into account the complexity of industrial environments, allowing the controller to operate stably under various harsh conditions.

In summary, the WOODWARD 8256-016 speed controller plays an important role in industrial applications due to its wide application range, flexible signal input, multiple working modes, high integration,
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. 

8256-016 is manufactured by Woodward in the company”s easyYgen 3000XT series. The XT series has some updated features on the older 3000 series. Some new features include plug-in replacement,
power measurement level 1, editable screen, multi interface toolkit connection, etc. All details can be found in Woodward easyYgen manual 37582A

This model is the 3200XT-P1 (Package 1) version. A significant difference between the 8256-016 and similar 3200XT-P1-LT models is their operating temperature range.
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.
8256-016 is equipped with a monitor (not available on the 3100 model) and is designed for front panel installation.

The toolkit software used for controlling the generator set has multilingual functionality. English, French, German, and Japanese are just a few of the fourteen supported languages.
The built-in HMI has a color LCD and soft keys (now with dedicated buttons) for direct control of the 8256-016 device. Multi level password protection can prevent unauthorized changes.

The easyYgen 3000XT model 8256-016 has three freely configurable PID controllers. It provides input and output control (kW and kvar), as well as MCB and GCB synchronization (sliding/phase matching).
The generator set has four operating modes and the option to configure a manual circuit breaker control device.

We can perform simulation algorithms on Matlab.3. The role of frequency converter1. Frequency conversion energy savingThe energy saving of frequency converters is mainly reflected in the application of fans and water pumps. In order to ensure the reliability of production, various production machines have a certain margin when they are designed to be equipped with power drives. When the motor cannot operate at full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in a waste of electrical energy. The traditional speed adjustment method for fans, pumps and other equipment is to adjust the air supply volume and water supply volume by adjusting the opening of the baffles and valves at the inlet or outlet. The input power is large, and a large amount of energy is consumed in the interception process of the baffles and valves. middle. When using variable frequency speed regulation, if the flow requirement is reduced, the requirement can be met by reducing the speed of the pump or fan.The purpose of using a frequency converter for a motor is to regulate speed and reduce starting current. In order to produce variable voltage and frequency, the device first converts the alternating current from the power supply into direct current (DC), a process called rectification. The scientific term for a device that converts direct current (DC) into alternating current (AC) is “inverter”. Generally, an inverter converts DC power into an inverter power supply with a certain fixed frequency and voltage. The inverter with adjustable frequency and adjustable voltage is called a frequency converter. The waveform output by the frequency converter is a simulated sine wave, which is mainly used for speed regulation of three-phase asynchronous motors, also called a variable frequency speed regulator. For variable frequency inverters that are mainly used in instrumentation and testing equipment and have higher waveform requirements, the waveforms need to be sorted and can output standard sine waves, which are called variable frequency power supplies. Generally, the price of variable frequency power supply is 15-20 times that of the inverter. Since the main device in the inverter equipment that produces changing voltage or frequency is called “inverter”, the product itself is named “inverter”, that is: inverter.Frequency conversion does not save power everywhere, and there are many occasions where using frequency conversion does not necessarily save power. As an electronic circuit, the frequency converter itself also consumes power (about 3-5% of the rated power). A 1.5-horsepower air conditioner consumes 20-30W of electricity, which is equivalent to a continuous light. It is a fact that the inverter runs at power frequency and has a power-saving function.
