getGeneratorInfo
Gets the information for all generators in the circuit
Contents
Syntax
Generators = getGeneratorInfo(DSSCircObj); Generators = getGeneratorInfo(DSSCircObj, generatorNames);
Description
Function to get the information about the generators in the circuit and return a structure with the information. If the optional input of generatorNames is filled, the function returns information for the specified subset of generators, excluding the miscellaneous parameters mentioned in the outputs below.
Inputs
- DSSCircObj - link to OpenDSS active circuit and command text (from DSSStartup)
- generatorNames - optional cell array of generator names to get information for
Outputs
Generators is a structure with all the parameters for the generators in the active circuit. Fields are:
- name - Name of the generator.
- busName - Name of the associated bus.
- numPhases - Number of phases associated with the generator.
- enabled - {1|0} indicates whether this element is enabled in the simulation.
- nodes - the connection nodes at the bus
- current - average phase current output
- coordinates - Coordinates for the bus
- distance - Line distance from the bus to the substation
- phaseVoltages - Value of voltage magnitudes calculated from the complex voltage returned by OpenDSS. Length is always 3, returning 0 for phases not on the bus
- phaseVoltagesPU - Per-unit value of voltage magnitudes calculated from the complex per-unit voltage returned by OpenDSS. Length is always 3, returning 0 for phases not on the bus.
- voltage, voltagePU, voltagePhasorPU, phaseVoltages, phaseVoltagePhasors, ... phaseVoltagePhasorsPU, phaseVoltagesLL, phaseVoltagesLLPU, voltageLL, voltageLLPU - voltages and voltage phasors
- phasePowerReal - 3-element array of the real components of each phase's complex power injected by generator. Phases that are not present will return 0.
- phasePowerReactive - 3-element array of the imaginary components of each phase's complex power injected by generator. Phases that are not present will return 0.
- powerReal - Total phasePowerReal.
- powerReactive - Total phasePowerReactive.
- seqVoltages, cplxVoltages, seqCurrents, cplxSeqCurrents - zero, positive, and negative sequence voltages and currents magnitude or complex phasors
- losses - total real and imaginary power losses
- phaseLosses - real and imaginary power losses
- kW, kvar, kva - Rated power of the generator
- kV - Rated voltage.
- PF - Rate power factor of the generator.
