A system may include a model library configured to model a safety system, wherein the model library comprises a plurality of subsystem models, and each of the plurality of subsystem models is configured to derive a reliability measure. The system further includes a fault tolerance input and a maintenance policy input. The system further includes a dynamic risk calculation engine (DRCE) configured to use a user-defined set of the plurality of subsystem models, the fault tolerance input and the maintenance policy input, to derive a system risk for an apparatus.

Disclosed herein is an approach that validates the sensitivity of a working fluid parameter indicator in a system using centrifugal machines. In one aspect, a lead centrifugal machine and a lag centrifugal machine supply a working fluid to a distribution conduit. A working fluid parameter indicator measures a process parameter associated with the working fluid supplied to the distribution conduit by the lead centrifugal machine and the lag centrifugal machine. A controller validates the sensitivity of the working fluid parameter indicator to measure the process parameter associated with the working fluid as a function of operation of the lag centrifugal machine relative to the lead centrifugal machine during an operational test performed on the centrifugal machines.

Disclosed herein is a power consumer approach that monitors the occurrence of grid code events within electric power transmission operations. In one aspect, a grid code event meter is used to detect the occurrence of a grid code event. The grid code meter includes a metering component configured to obtain data for power-related parameters associated with consumption needs. A grid code criteria tracking component tracks the data related to the power-related parameters obtained by the metering component for compliance with grid code criteria required by a transmission company of a consumer for power quality and reliability. A grid code event detection component detects an occurrence of a grid code event in accordance with the tracked data for the power-related parameters.

Disclosed herein is an approach that presents unbalance information obtained from electrical assets in a manner that facilitates management of the electrical assets. In one aspect, a screen view is generated that provides a visual representation of the electrical assets as partitioned into one or more groupings that are each based on a common operational characteristic associated with the electrical assets. The screen view also contains unbalance information that is associated with each of the electrical assets in the one or more groupings and an indication of whether there is a presence of abnormal operation associated with each of the one or more groupings.

Disclosed herein is an approach that uses a wattmeter to determine hydraulic fluid parameters. In one aspect, a controller uses the electric power measured by the wattmeter to determine the power delivered to hydraulic fluid delivered by a hydraulic pump unit to a hydraulic fluid consuming device and the volumetric flow rate of the hydraulic fluid delivered to the hydraulic fluid consuming device by the hydraulic pump unit.
