Transient Stability Study
 Various types of fault at user defined location
 Detailed representation of excitation systems, turbines governors static var compensators, power system stabilizers and HVDC controllers
 Load Shedding
 Simulation of operation of voltage / current / frequency relays and distance relays
Relay Coordination
Gives new relay settings for improved performance and computer zone settings for distance relays. Relay coordination can be conducted for relays of all make and with user defined characteristics for overcurrent and distance relays. Simulation option available.
Voltage Instability Analysis
Designed to assess the risk of Voltage instability and margin of stability during sudden disturbances, under steady state conditions. It ranks the load busses based on the Lindex value and the highest Lindex indicates the system collapse point. The value of Lindex is zero at no load and 1 at the verge of collapsing point.
Harmonic Analysis
Performs threephase harmonic load flow to compute harmonic distortion factors. Calculates harmonic transfer and driving point impedances for both transmission and distribution power systems.
Dynamic Stability Analysis
Performs the dynamic stability analysis in both frequency domain(Eigen value analysis) and time domain.
Network Reduction
Provides the static and dynamic equivalents for the power system. In case of Static equivalent, program determines the bus admittance matrix (Y ) as seen from the desired nodes by bus eliminating the rest of the nodes. In case of dynamic equivalent, a single machine equivalent circuit is determined.
SubSynchronous Resonance
Frequency response method is used for analyzing the stability of subsysynchronous resonance, as modelled by a number of synchronous machines and an extensive series compensated transmission network. The method allows the simultaneous
detailed modelling of all machine shafts and control loops and hence permits investigation of possible interaction in the subsynchronous resonance frequency band between machines in different plants.
Electro Magnetic Transient Analysis
Performs both transient and dynamic over voltage studies. The highest discharge currents and enrgy stresses for the protective equipment and to coordinated them with withstand levels of the protected equipment is determined. Over voltages, which are caused due to energization of lines, transformers and shunt elements, during fault inceptions and on clearing of faults are calculated.
Line and Cable Parameter Calculation
Program calculates positive and zero sequence parameters of the overhead lines and cables used in single and multiphase configurations over a wide range of user defined frequencies and temperatures. It also calculates the mutual impedance between power and communication lines.
Long Term Load Forecast
Long Term Load Forecast module is designed for forecasting the energy demand during the planning stages of a power system. The salient features of this tool are
 Generality to apply for any type of load data
 Can accommodate any number of independent variable,which are very significant.
 The method adopts multivariate regression techniques forforecasting
