Common use of Power Consumption Clause in Contracts

Power Consumption. The fidelity in modelling power consumption may vary. The average power regardless of mode could be represented (1), or the different power levels in each mode (2), or a varying power within each mode (3). Establishing the total power or energy consumption over an interval of time would then be treated differently in each case. Alternative 1) would mean that the genericConstraintValue over all GenericConstraints with Alternative 2) would mean that each unique mode assignment for the integrated architecture is traversed, and the genericConstraintValue over all GenericConstraints with genericConstraintType powerConsumption are multiplied by the time spent in this mode and added. Alternative 3) would mean that simulation or analytical means are used to establish the instantaneous power in each component. Because power is allowed to vary, the component power must be defined by a function. Typically, power is related to the nominal functional behavior of the component. The genericConstraintValue for a powerConstraint could thus be an expression with nominal signals as operands. This is however not supported by EAST-ADL. The instant view of the power consumption can be used for integrating to energy consumption, averaging power levels for certain intervals, finding peak values, etc.
