21 Picote, Portugal2 Herdecke, GermanyA power plant’s one and only objective is to fully meet theelectricity demands for a maximum of time at the lowestpossible cost. Therefore, efficiency, reliability and availabilityare crucial, and it is of highest importance that the machinesare kept operating under optimum conditions. A key factorto meet these d emands is to be able to support early faultdetection and preventive maintenance techniques.This is the focus of OnCare.Health Hydro, which is designedto obtain early detection of incipient damages, reduction ofinspection and repair work, and clear planning options fortimely inspections.Among series of monitoring and evaluation methods for probableroot causes in machine behavior, vibration diagnosis and airgap analysis are examples of well-known and acknowledgedmachine monitoring methods in the hydropower industry.Both have gained importance and have become part ofcondition-based maintenance for hydroelectric equipment,and match today’s needs with respect to measuring technology,data processing and evaluation procedures.3
Condition monitoring systemOnCare.Health HydroOnCare.Health Hydro is an online monitoring, analysis and diagnosissystem developed by Voith Digital Ventures, combining the know-how andexperience of international hydropower operation from Voith, which hasdeep knowledge and expertise in hydropower layout and design.To meet various demands for different types, sizes and operation modes of hydropower machines, we offer: Highly scalable systems Custom-tailored solutions regarding protection, monitoring,analysis and diagnosis Predefined standard configurations for sensors to assurereliable and safe measurementOur modules are designed as an integral part of our controlsystem family, making it more beneficial, because no interfaces have to be clarified, and information already available inthe control system does not have to be acquired twice.To maximize the flexibility, the system is designed in three hierarchical levels: Monitoring Analysis DiagnosisWe also offer flexible solutions for hardware configuration andintegration to be implemented into your existing plant controlsystem.Overall benefits OnCare.Health Hydro Optimized total cost of ownership Reduced costs Increased availability Voith know-how implementationHardware configurationLocal expertsupportAutomateddiagnosisRemote expertsupport routerRemotecommunication linePlant Bus TCP/IPUnit 1Monitoring cubicleUnit 2Profibus DPAir gap monitoringRelay out7Vibration monitoringRelay outControl system100 % time-synchronous 50 kHz sampling rate per channel and high 24 bit resolution.All types of vibration sensors can be connected (μm, mm/s, m/s²).Internal power supply for IEPE sensors available.4Unit n

Monitoring interfaceReliable measurement and signal processing plus a wellengineered unit protection concept are considered to beof paramount importance for plant safety.MonitoringThe highly sensitive measuring systems that are adapted tothe requirements of hydropower machines ensure effectivecondition-based monitoring and maintenance, and thus increasethe life cycle of rotating machines as well as increasing plantavailability and reliability.Additional featuresOur data acquisition devices include logical functions basedon parameters that generate trip signals to be transferred tothe mechanical protection of the unit. This requires simple and1reliable solutions that, at the same time, need to be flexibleto meet various machine characteristics that are highlydependent on operating conditions.To provide plant safety, the primary tasks of monitoring are to: Identify the plant’s individual optimum condition Recognize imminent damage early on Optimize modes of operation Allow for scheduled maintenanceFor complex excitation mechanisms with high dependency onspecific operation conditions of the unit, special monitoringtechniques are applied. The HyCon MD monitoring moduleevaluates all measurements and characteristic values as afunction of operation mode and operation point.Unit monitoring6User friendly interface
Intelligent measurement andanalysis for additional benefitsIn order to add on benefits for plant operators, our systems aredesigned to efficiently support predictive maintenance strategies.More than monitoringMost monitoring systems only measure values and createalarms based on limit values. In order to extend the benefit2 the plant operator, the system must be able to efficientlyforsupport preventive maintenance strategies.To fulfill this demand, the following prerequisites must be met: Highly sensitive measurement technology with adaptedanalysis techniques Diagnostic intelligence for proper selection of specificparameters and comparison of the measured valueswith the expected behavior, depending on specific plantconditions and machine operation modes Tailor-made systems to meet specific conditions suchas very low speed or various operating modes withhighly volatile excitation requirements Precise machine monitoring through intelligent measuringand analysis systems covering analytic evaluation ofpre-processed values from the measurement device, forexample, frequency analysis providing frequency-selective2observation results, and the calculation of further hydrospecific characteristic values.Statistic moduleTo increase the information content of, for example, vibrationsignals, as well as to represent the great variety of vibrationrelated factors, our statistic module is flexible to provide measurement values from any desired process variable. Differentmeasurement planes, signals and key parameters can thus becompared.Our modules are specifically designed to meet these a dvancedrequirements.Shaft vibrationShaft signal analysis7
Value added for the operatorExpert diagnosisOnCare.Health Hydro, with its flexibility and adaptive modularconfiguration, provides a powerful tool for you to do reliablediagnostics for safe operation all the time.Many monitoring systems are available that are able to measure and present results using standard evaluation methods.In contrast, Voith, as an equipment manufacturer, understands the process and knows how to interpretthese measurements. This knowledge is integrated in theOnCare.HealthHydro system – a clear added value for theplant operator.Diagnosis user interfaceClear and basic information on the machine’s condition is presented to the operator through user-friendly interfaces.Whenever information about a problem becomes evident, the1results are passed to the user as a list of clearly identifiedfailure causes including error probabilities.In order to automate diagnostic tasks, a knowledge databaseprocesses the results of the analysis.Unit monitoringProcess parameters &operation mode8Signal preprocessing and calculationVibration signalsExpert diagnosisLong term dataarchiving systemIndividualfault rulesCause probability bars
