Protect, forecast and increase asset availabilitySiemens Diagnostic Monitoring and Protection are part of the Omnivise Availability suite and cover condition monitoring solutions, machinery protection solutions and related services. It consists of hardware components and software tools for data analytics relying on sensors. Continuous condition monitoring is the corner stone of transparency on the functioning of processes and aggregates. It is also called anomaly detection and does not only reveal deviations from normal behavior, but also indicates what is happening, when and where.
Machinery Protection - Highest safety and availability of your plant assets
Machinery Protection is fully redundant, scalable and is thus designed to provide extremely high fault tolerance.
Vibration Monitor - The only genuine early warning system
Vibration Monitor (formerly known as VIBROCAM 5000) is the diagnostic monitoring solution for the analysis and diagnostics of all power plant machinery.
Anomaly Monitor - Early detection of anomalies
Anomaly Monitor is a system for continuous monitoring of one power plant or a whole fleet in steady-state and transient operating condition.
Highest safety and availability of your plant assets
Machinery Protection is fully redundant, scalable and is thus designed to provide extremely high fault tolerance. Safety levels for the system are extremely high thanks to its three fully implemented redundancy nodes. The system can be integrated into the Siemens I&C and supports configuration from the plant DCS. PROFIBUS and MODBUS interfaces are available and can replace 0/4…20mA interfaces. The technology implemented into Machinery Protection also features digitalization throughout the system, “voting” within the system (on-board-voting) and short response time.
The main objective of the Siemens Machinery system (also called VIB3000) is to fulfill safety and availability targets without compromise by protecting the machine and the environment from the consequences of machine failure.
Security Analysis: holistic security assessment to assess security levels
The only genuine early warning system
Vibration Monitor (formerly known as VIBROCAM 5000) is the diagnostic monitoring solution for the analysis and diagnostics of all power plant machinery. Monitoring and detection of abnormal machine behavior at the earliest possible point enables the planning of cost-effective solutions. By sensitive diagnostic monitoring, Siemens Vibration Monitor provides information on possible mechanical causes of abnormal behavior (unbalance, bearing damage, incorrect alignment, cracks and loose parts). The solution includes all of the tools used for analysis and diagnostics and thus for determining the causes of machinery health issues. Siemens Vibration Monitor is the only genuine early warning system for abnormal machinery conditions that can be integrated into the main Siemens SPPA-T3000 control system. Vibration Monitor offers many features which enhance availability, make availability more predictable and cut maintenance costs, such as:
- maximum possible measurement accuracy through rotor-triggered data acquisition
- maximum sensitivity to changes, using up to 1000 automatically derived limit values per vibration measuring point
- comprehensive monitoring of event patterns for current and historic machine condition as well as start-up and shut-down
- a unique archiving concept with event-oriented storage of complete data sets and tools for automated data interpretation and
- numerous additional data analysis functions such as statistical assessments or transient recorder functionality
To consistently implement condition-based maintenance strategies, in-depth knowledge of the power plant assets’ condition is required. Siemens Vibration Monitor offers condition monitoring for any kind for turbines (Siemens or other manufacturers), any kind of fan (induced-draft, forced-draft), any kind of pump (feed water, condensate, cooling water), compressors, hydro-generators, gearboxes, electric motors, conveyor drives, etc. as well as for any kind of DCS (Siemens or third-party).
Early detection of anomalies
Siemens Anomaly Monitor, also part of the Omnivise Fleet Management solution is a system for continuous monitoring of one power plant or a whole fleet in steady-state and transient operating condition. Early detection of faults prevents machine failures and avoids high repair costs. Through asset diagnostic technology, Anomaly Monitor provides deep insights into the conditions of plant assets and consolidates relevant information on fleet-wide monitoring screens. Anomaly Monitor uses machine learning algorithms to train the normal behavior of an asset or process from historical data of related measurements. For each asset to be monitored, one or more databased models can be created and trained. After models have been trained and learned the normal behavior of the respective asset, new measured data gets continuously compared with what is expected based on the training data. This happens within reasonable cycle times, normally in the seconds range. Consequently, the user is informed extremely fast in the case of any deviations from the normal values.
Anomaly Monitor supports the following core functions that support the workflow from model creation, data handling to continuous monitoring:
- Correlation Analysis
- State estimation (core Anomaly Monitor algorithms)
- Sensor validation
- Computed Sensors
- Events (alarms)
- Data Output (Estimation Results, Residuals)
