About the library

The library is created to provide the models of devices of technological processes. The library is not static, but based on the module JavaLikeCalc, allowing to create calculations on the Java-like language.


To address the functions of the library you can use static call address "DAQ.JavaLikeCalc.lib_techApp.{Func}()" or dynamic "SYS.DAQ.JavaLikeCalc["lib_techApp"]["{Func}"].call()", "SYS.DAQ.JavaLikeCalc["lib_techApp"].{Func}()". Where {Func} — function identifier in the library.


To connect the library to the project of the OpenSCADA station it is possible by downloading the attached file of the database, placing it in in the database directory of the station's project and creating the database object for the DB module "SQLite", indicating the database file in the configuration.


For each function it was evaluated the execution time. Measurements were made on the system with the following parameters: Athlon 64 3000 + (2000MGts) + ALTLinux 5.1, 32bit by measuring the total execution time of the function when you call it 1000 times. Selection was made for the smallest value of the five computations. Time is in angle brackets and is measured in microseconds.

1 Conception

The basis of the model of each unit is the calculation of the input flow and output pressure based on the input pressure and output flow. In general, models of technological devices are described by difference equations for discrete machines.


Based on the functions of this library you can easily and quickly build models of technological processes in the module BlockCalc by combining the blocks in accordance with the technological scheme. Example of combination of several devices of the technological scheme is shown in Fig. 1.

Fig. 1. An example of the block scheme of the technological process.

The basis of the model of any technological device are two basic formulas, namely the formula of flow and pressure. The canonical formula of the flow computation for the pipe section, or restriction of flow area is given by (1).


 (2 Кб) (1)

Where:
F — mass flow (t/hour).
S — section (m2).
Qr — real density of the medium (kg/m3).
∆P — pressure drop (at).

The actual density is calculated by the formula (2).

 (3 Кб) (2)

Where:
Q0 — density of the medium under normal conditions (kg/m3).
Kpr — coefficient of compressibility of the medium (0,001 — liquid; 0,95 — gas).
Pi — input pressure (at).

Each tube makes the dynamic resistance to the flow associated with the friction of the pipe walls and that depends on the flow velocity. The dynamic resistance of the pipe is expressed by (3). The total flow of the medium, taking into account the dynamic resistance is calculated by formula (4).

 (6 Кб) (3)

Where:
∆P — pressure drop (at), the resistance of the pipe walls to flow of the medium.
Kr — coefficient of friction of the walls of the pipe.
D — diameter of the pipeline (m).
l — pipeline length (m).
v — flow velocity in the pipeline (m3/hour).

 (4 Кб) (4)

Equation (1) describes the laminar outflow of medium to critical velocities. In the case of exceeding the critical flow velocity the calculation is made by the formula (5). A universal formula for calculating the flow at all speeds will have the formula (6).


 (3 Кб) (5)

Where:
Pi — pressure at the beginning of the pipe.


 (5 Кб) (6)

Where:

Po — pressure at the end of the pipe.

In dynamical systems the change of the flow at the end of the pipe does not change instantaneously, but lags behind the time travel of the medium plot from the beginning of the pipeline to its end. The time depends on the length of the pipe and velocity of the medium in the pipe. Delay of the flow changing at the end of the pipe can be described by formula (7). The resulting formula for calculating of the the flow in the pipe, taking into account the above features, written in the form (8).


 (2 Кб) (7)

Where:
Fo — flow at the end of the pipe.
t — time.
v — velocity of the flow = F/(Qr*S).

 (9 Кб) (8)

The pressure of the medium in the volume is usually calculated identically for all cases by formula (9).
