  • Page 21: Functional Description

    BE2000E functions are illustrated in the block diagram of Figure 3. A detailed description of each function block is provided in the paragraphs under the heading of BE2000E Function Blocks. BE2000E operating features include four operating modes, four protective functions, startup provisions, reactive droop compensation, underfrequency compensation, and an auxiliary analog input.

  • Page 22: Contact Input Circuits

    This input allows adjustment of the BE2000E regulation setpoint by the application of a positive or negative dc voltage across terminals A and B. Voltage up to +3 Vdc may be applied at this input. The circuit induces a 1,000-ohm burden on the dc source.

  • Page 23: Communication Port

    Closing a contact across terminals 52J and 52K disables var/power factor control. An open contact enables the BE2000E to control the generator reactive power in either the var or the power factor mode. For more information, refer to the Parallel Generator Compensation (52L/M) contact input.

  • Page 24: Be2000E Operating Features

    Var Control Mode In Var Control mode, the BE2000E maintains generator vars (volt-amperes, reactive) at a set level when paralleling with an infinite bus. The BE2000E calculates generator vars using the sensed generator output voltage and current quantities and then adjusts the dc excitation current to maintain vars at the setpoint.

  • Page 25: Underfrequency

    When generator frequency drops below the selected knee frequency setpoint, the voltage setpoint is automatically adjusted by the BE2000E so that generator voltage follows the selected PU (per unit) V/Hz curve. When operating on the selected PU V/Hz curve, the Underfrequency Active indicator flashes on the front panel and in BESTCOMS™-BE2000E software.

  • Page 26: Generator Soft Start

    Overexcitation Limiting (Field Current) The BE2000E has a field current limit that is factory preset at 6.5 amperes. The limit is adjustable from 0 to 7.5 amperes with an adjustable time delay that has a range of 0 to 10 seconds. Both settings are made through the Windows communication software.

    Any setting changes made on a setting group screen must be sent to the BE2000E before viewing other screens. Otherwise, the setting changes will be lost. A single setting change can be sent to the BE2000E by pressing the Enter key on your PC keyboard.

  • Page 45: Receiving Settings

    Settings are saved in nonvolatile memory (EEPROM). In the event of a power loss, these are the settings that are active at power up. If settings are changed and sent to the BE2000E but not sent to EEPROM, the changed settings are lost if BE2000E operating power is lost. When exiting BESTCOMS-BE2000E or closing communication, you are asked if you want to save the settings to EEPROM.

  • Page 61: Pid Calculation Based On Input Values

    9287500995 Rev B Integral means that the BE2000E output is proportional to the amount of time that a change is observed. Integral action eliminates offset. Derivative means that the BE2000E output is proportional to the required rate of excitation change. Derivative action avoids excitation overshoot.

  • Page 62: Adding To The Pid List

    BESTCOMS-BE2000E enables you to print a list of BE2000E settings, save BE2000E settings to a file, and open a settings file and upload those settings to a BE2000E. a settings file may also be opened and edited within any text editing software.
