Page 34: Networked Systems
Networked Systems The members of the F2250 family are easily connected together to form a single networked system, with a number of sources for testing multiphase protective relays and system protection schemes. Simulators are connected to each other by two cables (three for parallel download) in a daisy-chain fashion, which forms a multi-drop network.
Page 35: System Communication
F2250 User Manual System Communication The firmware used by the microcomputer uses a special language and communications protocol, called DobleCoL, to control communications between the simulators over the IEEE-488 bus. Any simulator may broadcast a message over the IEEE-488 bus to all others, at any time. Only those addressed in the message respond, and perform whatever action is specified or required.
Page 36: Safety
Dangerous and potentially fatal voltages can be developed across the ARNING output terminals of any Doble F2250 Power System Simulator. Use extreme caution when turning on or using any F2250. Always turn the source output off and disable the unit before connecting, removing, or touching any output terminal or cable.
Page 37: Automation And Remote Control
F2250 User Manual Automation and Remote Control Any single simulator or networked system can be controlled remotely by an F2010 Minicontroller or by a host computer. Remote control is effected by the controlling device transmitting command messages to, and receiving status/data messages from, the unit to which it is connected.

F2250 User Manual The microcomputer also receives status, range, and error messages from the power amplifiers and output controls via the DCT. It uses this data to communicate operating information and error conditions. The microcomputer transmits messages to the DCT that illuminate the appropriate front panel LEDs and/or sound a beeper.
Page 102: Amplitude Control
Amplitude Control Amplitude Control The maximum output of each DAC occurs at 90.0°, when the digital value (1.000) equals a precision reference potential. The DAC thus produces a stepped sine wave of constant rms amplitude at the specified frequency and phase angle. This signal is applied to the reference input of a multiplying DAC converter (XDAC).
Page 103: Phase Angle Control
F2250 User Manual Phase Angle Control Phase angle relationships are obtained by using a specified phase angle to offset the source's RAM pointer. The phase angle is defined by the source's PHASE ANGLE switches, an F2010 Minicontroller, or a host computer.

F2250 User Manual Minicontroller Operation F2250 front panel controls are engineered for basic, steady-state control of voltage and current phasor quantities. The source control of the F2010 Minicontroller expands the functions of the F2250 to provide dynamic test functions of instantaneous switching and variable-rate changes between two values of voltage, current, phase angle, and frequency for one source.
Page 130 Application Minicontroller functions are used for various test operations including: • Dynamic tests of any relay measuring function • Automated: trip frequency, reach, M.T.A., pickup/dropout tests; all without manual adjustments • Timing relay response • Generating slip frequencies for automatic synchronizer generator/bus simulation The F2010 can control the amplitude and phase angle of either SOURCE 1 or SOURCE 2 of one F2250.

Page 139: Value/ Time F2820
F2250 User Manual ∆ VALUE/ ∆ TIME F2820 Automatically varying a parameter with respect to time is a useful ACTION test method. It provides highly repeatable pickup/dropout/reach/M.T.A. results because the rate-of-change in voltage, current, phase angle or frequency is controlled precisely. Under manual control, the rate-of-change may vary, and therefore, results may be incorrect due to the relay measuring circuit response.

Source Resolution Source Resolution Precise measurements of relay operation require high resolution in test parameters. Stable, Active Sources voltage and currents with a resolution of 0.1% of full scale, minimum, provide meaningful test results. Clearly, a more precise definition of voltage relay pickup is attained with a source resolution of 0.01 V rather than 1 V.
