Plant-labeling system

The power plant labeling system (PPS) is a plant identification system for uniform and

systematic identification of power plants . It has been used since the early 1980s, farmers and power plant

power plant operators the unique name and identification of all components of a power plant. The power plant

marking system from VGB - Working Group plant identification and documentation maintained and further

developed. Be regulated, the PPS indicator in the Directive VGB B105 and B106.

Structure [ Edit ]

The labels referred to PPS consists of a 15 - to 17-digit letters - and numbers combination. The letters are

generally to classification of the systems and assemblies used. The numbers are usually the count.

The PPS distinguishes three types of signs:

Procedural identification , encryption, plant and equipment in the power plant process

Position marking , to encrypt locations and slots in electrical systems

2 | P a g e

Space identification , encryption, the topographic location of facilities and equipment in buildings

The identification of PPS follows a fixed structure , which is to outline steps oriented. It increases from left to

right of detail of the plate. The structure of the outline levels is a lpha- n umerisch. In the following, A for letters

and N used for numbers. Between the levels of each organization a space is set. When the installation is

marking the division between stage 1 and 2 outline the character " . " (Dot) is set.

Points that are used only when needed, are in parentheses.

Outline level 0 - Total plant [ Edit ]

The first stage refers to the overall system structure and has counted character. It consists of a number or a

letter.

Outline Level 1 - Functional overall system [ Edit ]

The second outline level refers to a functional system as a whole in the overall system. It consists of 3 letters

and 2 digits with an optional leading digit. The letters are assigned according to a predetermined key systems

in power plants. Here, the first letter indicates (from left) are the main systems (so-called main groups ), then

the following letters denote the further breakdown into sub-groups. The following two paragraphs have

character and be counted as F Ndenotes count.

Outline level 2 - unit [ Edit ]

The third stage refers to a structure unit in the subgroup. It consists of two letters and three digits. The letters

are assigned according to a predetermined key items (for example, a measurement) in power plants. Here, the

first letter refers to a group of units, and the subsequent letter then referred to the further breakdown into sub-

groups. The following numbers have counted character. Many companies and equipment manufacturers use

here a further characterization, in the first numerical number is a functional addition. This means AA3NN that it

is a vent, a draining and AA4NN AA6NN a measuring point.

Outline Level 3 - Equipment / signal indicator [ Edit ]

The fourth stage structure called a resource or signal indicator in the aggregate. It consists of 2 letters and 2

numbers. The letters are according to a predetermined key operation means (for example, a drive)

assigned. Here, the first letter refers to a group of units, and the subsequent letter then referred to the further

breakdown into sub-groups. The following numbers have counted character. If the signal indicator there is a

defined assignment, eg XB01 is the "up" acknowledgment from a drive. XB51 is the "Not In" acknowledgment

of the same drive, XB02 the "CLOSED" feedback and consequently XB52 the "non CLOSED" feedback.

Example [ Edit ]

In a flowsheet is the name: 1 2LAC03 CT002 QT12

Outline level 0:

The block 1 of a power plant site receives in this first stage, the labeling

Outline Level 1:

For the 3rd feed water pump in the second water - steam cycle labeling is 2LAC03. This means:

Main group 2L: 2 Steam, water, gas circuit

Subgroup (2L) A: feedwater system

Subgroup (2LA) C feed water pump system

Counter (2LAC) 03: third feedwater pump system

Outline Level 2:

For the second Temperature measurement is the identification CT002. This means:

Main Group C: Direct measurement

Subgroup (C) T: temperature measurement

Counter (CT) 002: second temperature measurement

Outline Level 3:

For the 12th Sensor well as sensing devices shall protect the labeling QT12. This means:

Main group Q: Instrumentation and control equipment

Subgroup (Q) T: Protection tubes and thermowells as transducer protection

Counter (QT) 12: Twelfth protective tube or thermowell

With the example above, the 12 Thermowell at the 2nd Temperature measurement at the 3rd Feed pump in

block 1 denotes a power plant site.
