− synchronization of the time of the controller and the visualization application with an external source of exact time;

− self-diagnosis of the technical means of the system;

− archiving of the information entered by the operator on the test being carried out;

− issuance of reports (protocols) in electronic form, on electronic media;

− generation of threshold violations when the set values ​​are exceeded;

− determination of faults in control circuits;

− detection of faults in the main circuits.

2.4 Controller cabinet functions

The controller cabinet must provide the following functions:

− processing and registration of input/output signals;

− execution of algorithmic sequences;

− issuance of executive actions (commands) for the implementation of bench testing algorithms;

− measurement of electrical parameters of the network;

− warning and emergency signaling on the deviation of the electrical network parameters from the regulatory and emergency limits.

Specifications of the controller cabinet are shown in Table 1.

For input-output channels, a reserve is provided in the amount of 20% of the existing volume of input-output channels.

2.5 Functions of the automated workplace of the STB operator

The operator's workstation should provide the following functions:

− parameterization of the testing process;

− configuring the sequence for testing;

− control, registration, signaling of changes in the parameters of the electrical network of the stand;

− display and registration of the stand equipment state;

− registration of operator's actions;

− remote control of technological equipment.

Registration of data on the workstation is carried out in the archive. The archive depth is 3 months.

The operator workstation should include a portable computer and a SCADA package.

The developed application software must be able to be configured for a specific type of blocks of an integrated switchgear control valve (cell PRODUCT).

 


 

3 PROJECT DESCRIPTION

3.1 Software

The application software (APS) of the STB is developed on the basis of the licensed basic software (BSS) of the Schneider Electric company and consists of the following components:

− the Unity Pro XL tool system of version not lower than V6, which supports the development of application tasks of programmable logic controllers (PLC) in five languages ​​according to the IEC 61131-3 standard;

− Vijeo Citect tool package of version not lower than V7.2 for configuring an automated operator's station for an applied task.

The basic software is accompanied by the software documentation of the company-developer of the basic software (in Russian or English), sufficient to accompany it.

3.2 Project boundaries

The work of CJSC "Contractor" on this project is limited to:

− obtaining information from the terminal assembly installed in the controller cabinet;

− displaying information about testing on a portable computer (AWP);

− transfer of information, if necessary, to the external network of the enterprise.

The main part of the work on creating application software and configuring controllers is carried out at the site of CJSC "Contractor", factory (preliminary) tests are carried out at the site of JSC "Customer".

The final part of the work of CJSC "Contractor" is carried out in the form of commissioning work together with the Customer's representatives and under their supervision on the site.

3.1 The structure of the software and hardware of the stand for testing blocks PRODUCT

The structure of the software and hardware complex of the stand is shown in Figure 1.

Table 2 lists the equipment for the implementation of this project. This equipment is not purchased or manufactured within the framework of this project (its cost is not taken into account in the TCP). Purchase of equipment, design documentation and assembly of the controller cabinet will be carried out by the Customer.
