Systems and methods for gas turbine operational impact modeling using statistical and physics-based methodologies are disclosed. According to one embodiment of the disclosure, a method can include receiving, by one or more processors, operational conditions data associated with a hardware component of a gas turbine; based at least in part on the operational variation data, applying, by one or more processors, statistical methods to establish an operational profile of the hardware component; receiving, by one or more processors, operating parameters and operational conditions data associated with the hardware component; based at least in part on the operating parameters and the operational conditions data, applying, by one or more processors, physics-based methods to establish an operational impact factor of the hardware component; and based at least in part on the operational profile and the operational impact factor determining, by one or more processors, a probability of a failure of the hardware component within a time period.

An apparatus performs methods for device diagnostics based on signals from digital outputs. The apparatus includes an input/output module with a digital output module to be coupled to a device. The input/output module measures one or more characteristics of a digital signal provided by the digital output module, where at least one of the one or more characteristics of the digital signal is associated with an output current of the digital output module. The input/output module also performs one or more diagnostics using the one or more measured characteristics of the digital signal.

This disclosure relates to the analysis of data generated by one or more connected systems and devices. Operational data obtained by one or more connected devices and/or systems, such as a connected thermostat and/or wind turbine system, may be used to detect and/or predict impending failures and/or suboptimal performance. By detecting and/or predicting anomalous system and device performance, various actions may be taken to improve system and device performance and mitigate failure conditions.

Methods and systems of the present disclosure are directed to monitoring an equipment apparatus and alerting an individual of a malfunction. The system is integrated with a target equipment apparatus to monitor operating conditions. When a baseline operating condition changes to an alarm condition, an alarm signal is sent to a monitor. The system also includes an external power supply so that the alarm signal can still be sent in the event of a power failure. The monitor sends a message output to a communication control module that includes a radio transmitter, such as a cellular radio transmitter or a satellite radio transmitter. The radio transmitter transmits a message to a receiver, such as a cellular phone or a satellite phone. The messages are sent repeatedly until the baseline operating condition is restored. The system can thus be used in methods to provide fast, reliable, and inexpensive remote monitor equipment apparatus such as heating systems, control systems, power systems, electrical systems, mechanical systems, and the like.
