  • Start a generator from a cold-state
  • Load a generator until it reaches to synchronous speed
  • Use frequency-dependent machine and network model
  • Utilizes User-Defined Dynamic Models Program
  • Special dynamic turbine actions during start-up
  • An expansion to the Transient Stability Analysis Program

 

Generator Start-Up Software Capabilities

  • Study quick recovery of power to critical loads
  • Determine optimum loading time
  • Schedule loading sequence
  • Analyze generator & motor starting behaviors
  • Study governor & AVR behaviors during starting
  • Simulate diesel generator starting for critical applications such as nuclear generation plants
  • Evaluate power recovery to critical loads when power grid connection is lost
  • Start a stand-by generator from cold-state under normal & emergency conditions
  • Simulate motor acceleration & rejection
  • Automatically simulate relay actions during analysis

 

Flexible Operations

  • Generator parameter correction due to saturation effect
  • Initial field flashing circuit & switching time
  • Detailed & user-programmable speed-governor system control
  • System switching controlled by relay actions
  • Variety of relay controls (Volt, Hz, V/Hz, dHz/dt)
  • Motor acceleration at under-voltage & under-frequency conditions

Dynamic Models

  • Exciters
  • Automatic Voltage Regulators (AVR)
  • Governors
  • Turbines
  • Power System Stabilizers (PSS)
Using full frequency-dependent machine and network models, the program analyzes cold-state starting of generators under normal and emergency conditions. The entire generator start-up process includes automatic control relay simulation and dynamic behaviors of exciters-AVR, governor, turbine /engine, and Power System Stabilizers (PSS).
It can be utilized to simulate detailed dynamic responses of the starting generator, test emergency loads including motors, MOV and others connected to the generator before it reaches the synchronous speed and rated voltage.
