GENSIM Test Set

GENERATOR SIMULATOR FOR EXCITATION SYSTEM TESTING

Larger View

A microprocessor based Excitation System test set intended for use on all modern excitation systems & voltage regulators, both analog and digital.

The GENSIM^® test set is designed for set-up calibration, maintenance testing, and troubleshooting. This equipment will simulate generator and exciter operation in order to safely perform a complete test of the excitation system & voltage regulator and related protective devices, while the Turbine-Generator is shut down.

Set-up your Excitation Systems to provide the maximum amount of VARS that the Generator can safely provide in order to support the power system needs and interconnection requirements.

Comply with NERC and WECC excitation system voltage regulator reliability standards requirements.

All components are contained within one

portable case, 13" tall 15" wide 11.5" deep,

weighing approximately 40 pounds

APPLICATIONS:

• Use prior to start-up of a new or overhauled excitation system in order to eliminate many hours of costly and risky test operation at full speed, no load.
• Use during periodic maintenance outages in order to verify that the excitation system protective devices are set correctly and functioning properly. The protective devices are utilized to prevent the generator field from overheating; prevent the generator stator core from experiencing excessive flux & end iron heating damage; and to prevent the machine from losing synchronization with the power system.
• Use for troubleshooting an excitation system in order to locate the problem without operating the machine and exposing the generator to a potentially damaging over-excitation incident.
• Use for checkout of auto synchronizers. By utilizing one phase of the simulated PT voltage for the generator PT input to the synchronizer and a fixed voltage (i.e. 120 volt 60 Hz from a wall outlet) for the running system PT input to the synchronizer.
• Use the 3-phase variable voltage and frequency for checkout and calibration of volts per hertz protective relaying.
• Use the GENSIM outputs for checkout and calibration of various Watt/Var transducers and metering.

FEATURES:

• Requires only a single-phase 85-264 volts AC 50-60 Hz power source.
• The 3-phase output voltage is regulated and balanced to simulate the generator PT's.
• The 3-phase output voltage amplitude and frequency are adjustable from 0 to 175 volts AC and from 40 to 72 Hz.
• Single-phase current output of 0 to 7 amps is standard. Three phase current output available as an optional feature.
• The phase angle relationship between the simulated generator voltage and current is variable over the entire generator operating range.
• An adjustable millivolt output of 0 to 200 mv. for shunt simulation with a 10mv. stepping function and external metering sensing.
• Three event timers with a resolution of 0.1 second.
• The event timers can be triggered three different ways:

1. Start/Stop push-button
2. Millivolt on/timer start push-button
3. External contact NC. or NO. (dry or wet with auto sensing)

• A DC voltage source of 0-600 volts to simulate exciter output.
• Digital LED readouts for all outputs.
• Complete set of test leads included.
• The test set is calibrated with a microprocessor software method. No hardware adjustments required.
