The neqsim.process.equipment.energy package supplies process units for conversion and allocation of electrical power, shaft work, heat, and chemical energy. These units connect through typed EnergyPort and EnergyBus objects and can be ordered explicitly in a ProcessSystem graph.

Equipment selection

Equipment	Primary role
EnergyConverter	Generic two-domain conversion with efficiency, capacity, idle loss, ramping, and trip state
LoadMappedEnergyConverter	Conversion with load-dependent efficiency
ElectricMotor	Electrical power to shaft work
Generator	Shaft work to electrical power
Gearbox	Shaft-work conversion with a speed ratio
Inverter	Electrical conversion with voltage and frequency quality
Transformer	Electrical conversion with a voltage ratio
PrimeMover	Chemical or fuel energy to shaft work
CommittedEnergyGenerator	Dispatchable generation with commitment constraints
ThermalUtilitySource	Typed heating or cooling utility supply
ThermalUtilityConsumer	Temperature-grade-aware thermal utility demand
EnergyNetworkSolver	Explicit ProcessSystem calculation node for one or more energy buses

MotorDriveTrain, MotorAssistedDriveTrain, CoupledProcessEnergySolver, and the time-series classes are orchestration services rather than equipment units. They coordinate the concrete equipment above across shared buses, mechanical shafts, repeated process-energy iterations, or time horizons.

Common contract

Energy equipment uses W internally. Unit-aware public APIs accept the units documented by the underlying energy stream or port. Each converter exposes a specification input, a calculated useful output, and a calculated heat-loss output. The process graph uses port direction and mode to order producers, network solvers, and consumers.

Before using an energy result for design or optimization, check:

• energy conservation across input, useful output, and heat loss;
• configured efficiency, idle loss, maximum power, and ramp limits;
• ValidationResult setup findings and trip state;
• energy quality such as utility temperature, electrical frequency, or shaft speed;
• unmet demand, curtailed supply, and balancing contributions in EnergyNetworkReport.
