Professor Turbine s Learning-Doc is made up of the following:
- Well written programmed-instruction that describes the turbine (or generator),related auxiliary systems, operation, and protection.
Written Learning Objectives that represent personnel’s need and the equipment under discussion.
- Heavy use of related drawings that provide a quality visual reference. Where applicable, the related drawing may include motion or some other form of interaction.
- Use of Check-Your-Understanding questions and answers throughout. These Q&A allows the reader to verify he/she understands the concept presented before proceeding.
- Use of recommended On-the-Job Learning Activities throughout. These OJLA will include getting out your plant prints/drawings to compare to what is presented in the Learning-Doc, taking anequipment walkdown to locate relative components, visiting the control room to look up instrumentation and control devices, interviewing experiencing personnel to gain from their operating experience.
- Study of Alarm Response issues to include why the condition is of concern, what is at risk, what are the probable causes, what actions should be considered, and what (if any) enablers or disablers are part of the logic, what is the source of the alarm, and how one may confirm the alarm condition.
- Final Examination. The final exam includes two questions for each of the Learning-Doc objectives with a 80% minimum required. Upon completion a certificate of completion is immediately provided with the individual͛s name, site, the topic completed and the date completed.
In summary–what do you have?
- High level of content targeting operational personnel, technicians and engineers.(Should include management on this list as well).
- Easy to read
- Written and reviewed by ex-OEM and ex-Utility personnel.
HPC has written (and continues to write) these Learning-Docs with four objectives in mind:
- Provide high quality training documentation. (High quality in technical content and deliver methodology).
- Provide for just-in-time training. Where you have a need to perform an operation that you havent done for a while. Use the Learning-Doc to review preliminaryrequirements, procedural items and expected results before you to the scheduled operation.
- Provide understandable, interactive, technical support when troubleshooting an operational problem. We cannot solve the problem for you, but what is it worth if, by getting quality information in front of you in an efficient matter, you can solve the problem 4+ hours earlier.
- Capture the knowledge and experience of the older generation and put that information in a system usable by the newer generations.
HPC has recently developed a set of Learning-Docs covering the GE-LSTG nuclear (BWR and PWR) steam turbine generator fleet. Covered 28 sites. The most often heard comment was this has far exceeded our expectations.Given this comment, HPC would like to believe that the nuclear fleet system engineers had pretty high expectations
Current client list (including those nuclear sites):
Cenovus Energy (Cold Lake Plant)
Duke Energy (Brunswick, Catawba & Oconee Stations)
Entergy (Grand Gulf, Pilgrim and Riverbend Stations)
Exelon Generation (Calvert Cliffs, Clinton, Dresden, Fitzpatrick, LaSalle, Limerick, Nine Mile Point, Oyster Creek, Peach Bottom, Quad Cities, Three MileIsland)
First Energy (Davis Besse and Perry Stations)
DTE (Enrico Fermi)
Next Era (Duane Arnold and Seabrook Stations)
PSEG (Hope Creek)
SaskPower (Queen Elizabeth, Poplar River, and Shand Stations)
Southern Nuclear (Plant Hatch and Vogtle)
TVA (Browns Ferry)
+ numerous individual participants
SYSTEM DESCRIPTIONS developed by HPC are “Reader-Friendly” documents that describe the function and operation of the particular systems. A typical system description is outlined as follows:
- Objectives (used when the System Description is to be used as a learning tool in addition to being a reference document)
- System Purpose
- System Overview
- Major Components and/or Sub-Systems
- Instrument & Controls
- System Operation
- Operational Alarms
OPERATION PROCEDURES are developed by HPC and include detailed step-by-step procedures on how to place a particular piece of equipment (or system) into service. Procedures usually include normal and emergency shutdown procedures as well. Some of our clients have desired these procedures to be used a learning tool. In this case, we authored explanations as to what a particular step in a procedure accomplished and why this was important.
PREVENTIVE MAINTENANCE PROCEDURES includes step-by-step procedures to properly care for equipment and/or systems as recommended by the OEM. These procedures often are very similar to what is provided in the OEM manual, but there is typically value-added in the sense that tools are described, only those steps applicable to the model in question are discussed, and consequences of not maintaining the equipment is emphasized.
LOOP DIAGRAMS are E&I type schematics that follow a signal from its origination to the final control instrument. For example, a pressure switch in the field results in a unit trip. The pressure switch as a device name, it is wired to a local junction box, there is usually a wire-tag that describes its connection to the terminal board in the control system, from the terminal board this signal may be digitized and stored in RAM, now it has a “signal name”. Wouldn’t it be nice to have identified, on one piece of paper, all the elements of this signal? This is what we accomplish on a loop diagram.
ALARM RESPONSE MANUALS are created for the benefit of operational personnel. It takes any alarm that might occur, describes the consequences of the alarm (in other words, what might be damaged and how serious it might be), and describes what action the operator should take in response. Should we get on the telephone and call someone, should we “trip” the unit, should it be unloaded, or what? If correlating data might be useful, this information is included as well.
TROUBLESHOOTING GUIDES takes the alarm response manual to the next level. In other words staff personnel must know determine what is the “root-cause” of the alarm and determine corrective actions. This may mean to replace a faulty pressure switch, to replace a “plugged” filter, to commence a clean cycle on some system, or to repair (replace) a circuit card.
HPC Technical Services has taken system descriptions to the next level and is excited to intoduce the POWER-DOC!!
- Interactive System Description with images of your equipment,
- Interactive, colorized P&ID making it much easier to read / follow and is a definite plus when tracing system piping and/or troubleshooting a system problem,
- Interactive Alarm Response Manual, and
- Interactive Instrument Loop Diagram
ALL IN ONE DOCUMENT!!!
First, HPC writes an equipment-specific system description, add images of your equipment, and includes your P&ID completely redrawn in color. This colorized version has the same detail as the original drawings and is a definite plus when tracing system piping and/or troubleshooting system problems.
Now comes the “Interactive” part. HPC adds links to the P&ID, images, and system description to allow the user to jump back and forth within the Power-Doc.
The resulting Power-Doc is a great tool for operating/troubleshooting each system.
Imagine! An alarm occurs in the control room. Operations personnel open the Power-Doc, select the appropriate Alarm Title, and operations immediately views a list of probable causes and probable operator responses. Need more information? Select the P&ID on the screen and go immediately to a highlighted P&ID of the system in question. Need more information on the instrument that serves as the alarm source? Select the instrument on the P&ID and see an Instrument Loop Diagram that shows the instrument, the wiring, and calibration data. Where relevant, a photograph of the instrument is shown as well. All of this is developed by personnel with significant equipment O&M experience!
- You get fresh, clear images of YOUR equipment
- A simplified (no lawyer-ease), easy-to-read system description
- A great looking NEW P&ID
- An easy access, computer based system operating & troubleshooting tool
