The scope of installation of 5 additional GPP4 Venetian Plywood Mill cells includes the following steps:

1. pre-design survey of the automation facility;

2. development and approval of design documentation for installation of 5 additional cells "GPP4 Yenisei plywood mill";

3. supply of necessary equipment;

4. installation works;

5. Commissioning activities;

6. development of operational documentation;

7. commissioning;

8. commissioning.

Installation works include:

1. Installation of 5 power meters on the designed cells at the installation sites provided by the manufacturer;

2. Replacement of the installed DRC overhead cabinet with a floor cabinet, with the possibility of placing 2 Sikon S70 units, ASKUE server, ¼ Switchboard, USV-1 and UPS in it.

3. Installation in an ASCAPC equipment USPD case according to the scheme of equipment installation (see 0660002009AKU sheet 9) with expansion of a system the additional network Sikon industrial controller C70, with association USPD in Profibus network;

4. Connection of current circuits, measurement and power supply circuits in accordance with factory documentation and design solutions;

1.5 Description of Activity Process

The process of activity in the operating conditions of ASKUE "GPP4 Yenisei plywood plant" consists of two main procedures:

- obtaining "GPP4 Yenisei Plywood Plant" data on electric energy (capacity) consumed for production needs;

- submission of the received data to the information system of OJSC Krasnoyarsk Energosbyt.

The procedure for obtaining data on consumed electric energy is completely automatic and consists of interconnected automatic operations of measurement, processing and storage.

The data transmission procedure to OJSC Krasnoyarsk Energosbyt is carried out in an automated manner according to the specified schedule.

The process of activity in the conditions of operation of ASKUE "GPP4 Yenisei Plywood Plant" includes maintenance of ASKUE components, use by GPP4 Yenisei Plywood Plant employees of accounting data provided by ASKUE in their daily activities.

2 main technical solutions

2.1 Decisions on the structure of ASKUE

ASKUE "GPP4 Yenisei Plywood Plant" is created as a hierarchical integrated automated system. ASKUE "GPP4 Yenisei Plywood Plant" includes the following hierarchy levels:

1st level - IIC level: includes 5 CP points and 39 existing TP points, 5 new TP points, as well as channelization equipment;

2nd level - DRC level: includes 1 existing Sikon C70, 1 new Sikon C70, combined with the existing Profibus network, existing Sikon 1 and channelization equipment;

3rd level - ASKUE server level: includes ASKUE server "GPP4 Yenisei plywood plant," channeling equipment.

To obtain reliable information on electricity in ASKUE, the synchronization of the time of the system with astronomical and system-wide clocks is carried out from the reference source of exact time GPS (global positioning system). On the basis of the signal receiver, a time synchronization device (CMS) operating as part of the CMS is made. The Unified Time Management System (SIS) covers all levels of the hierarchy.

All ASKUE equipment is connected to ~ 220V guaranteed power supply from UPS installed in DRC cabinet.

2.2 Solutions on means and methods of communication between the components of ASCUE

As a communication channel between the ASKUE DSS and the server of OJSC Krasnoyarsk Energosbyt, a GSMcommunication network is used.

To communicate Sikon C70 programmable controllers with each other, the Profibus Dual Local Area Network (DIN 19245) protocol is used, providing the ability to maintain common accounting groups. The network complex provides full protection of Profibus LAN at both hardware and software levels. The maximum data reception/transmission rate over the network is 93.7 kBaud.

Dedicated RS485 interface links are used as communication channels between counters and DRC.

Ethernetline connected through Ethernetcommuter is used as communication channel between DRC and ASKUE server.

In the designed ASKUE, system time synchronization is carried out using USV1 manufactured by ZAO ITF Systems and Technologies. Internal clock of DRC Sikon C70 combined into Profibus network, ASKUE server and internal clock of counters are synchronized from ESK1.

2.3 Solutions on the relationship of ASCUE with related systems, ensuring its compatibility

Commercial information is transmitted to OJSC Krasnoyarsk Energosbyt via the GSMcommunication channel.

The information shall be transmitted at least once a day.

2.4 System Operation and Diagnostics Solutions

ASKUE "GPP4 Yenisei Plywood Plant" provides the following modes of operation:

- regular;

- service;

- emergency.

In normal mode, all technical means operate as follows:

- measurement of regulated values and transmission of data between system levels;

- There is a system for ensuring a single time;

- information on commercial accounting is transferred to OJSC Krasnoyarsk Energy Company.

In the service mode of operation, technical equipment is maintained, technical components of the system are added or removed, and equipment is reconfigured.

The complex of technical facilities goes into emergency operation mode in case of equipment failures and failures of communication channels between the system components.

ASKUE "GPP4 Yenisei plywood mill" at all levels has built-in diagnostic functions.

At the IIR level, the counters perform self-diagnostics of the correctness of operation and, if there are causes that may affect its functioning, outputs error or warning codes.

At the DRC level, Sikon S70 performs self-diagnostics and event recording. DRC automatically generates an event log in non-volatile memory for recording:

- measurement registration start date;

- power supply interruptions;

- software and hardware restarts;

- time adjustments in DRC and each counter;

- software changes and DRC re-parameterization.

The content of the log is transmitted at the request of Pyramid Software 2000 to the ASKUE server.
