1.0 TEA FACTORY

Operation of flow control valve shall be as described below:-

1.1 Flow Control valve shall control the gas flow to tea factory as per the agreed quantity/ set point of each tea

factory. This will restrict the excess withdrawal of gas by the tea factory.

1.2 Normally, set point of flow control valve shall have the preset values as per the requirement. However,

generation of new set point shall be done form MCS according to flow requirement & fed to the RTU

controller. This set point will be generated by the operator from MCS depending upon the flow requirement

to the Tea Factories and availability of upstream pressure of PRS.

1.3 Tea factories can be permitted to withdraw the flow upto 150% of agreed quantity. Therefore, flow control

valve shall be designed based on this requirement and shall support this change wherever required without

any requirement of additional hardware.

1.4 In few tea factories gas is being utilized for tea processing and for running the gas based power generator.

This distribution is taking place at the downstream of flow control valve. Flow is being monitored through

turbine flow meter with electronic volume corrector (EVC) from both the line. Hence, it is important for the

Contractor to note that Consumption or requirement of gas in the gas based power generator is fixed. In

order to maintain the gas flow to tea factory at desired quantity, flow controller shall have the input, which

is the summation of both the flow meters, and set point shall be the desired quantity to the tea factory plus

the fixed flow to the gas based power generator.

1.5 Gas flow requirement to tea factories are not fixed throughout the year, this could change every month.

Customize pre-fix Month wise flow requirement (set point) of each tea factory shall enter or store into the

SCADA system. These set points shall automatically trigger the flow controller to control the flow at start

each month, and controlling shall be taken place accordingly.

1.6 At each tea factory, turbine flow meter is available with EVC. EVC of Turbine flow meter shall be

interfaced with RTU on MODBUS Protocol. Flow meter reading and all the necessary parameters available

in the EVC shall be recorded in RTU and transmitted to SCADA via telecommunication system. Flow

meter reading shall be used for controlling the flow.

2.0 SCADA PHILOSOPHY

2.1 SCADA severs at MCS, Server #A (Active) & Server #B (standby), RTUs at stations shall directly report to

Active server. All the servers and RTUs shall be routed through fire wall.

2.2 The system shall have complete SCADA database including the real-time database and integrated alarm/

event management summary for overall operations management & control for the entire network.

2.3 Two Servers i.e. Server # A (Active as primary) and Server # B (standby as secondary) shall be configured

in hot redundant mode. It can also be possible for Operator to select any one server as active and standby

initially. Each SCADA server shall be fully adequate to fulfill the entire monitoring, operation and control

requirements of the entire network.

2.4 SCADA system shall run on redundant LAN configuration LAN A (Primary) and LAN B (Secondary).

Both the servers shall have dedicated ports for primary LAN and secondary LAN.

2.5 Normally, Primary server shall poll all the RTUs on primary path. In case of any problem on primary path,

the Primary server shall poll the RTUs on secondary path. In case of problem in both primary and secondary

paths of primary server, Secondary server shall poll the RTUS on the primary path. In case of problem in

primary path of secondary server, RTU shall poll on secondary path of secondary server. Therefore, in case

of primary server failure, Secondary server shall Poll all the RTUs. The changeover to secondary server

shall accomplish within 1 minute automatically without causing any loss of data and control without any

effect on SCADA functionality. System shall inform the operator by flashing or pop of message on HMI

screen about the failed system by active SCADA server/standby server.

2.6 When RTU being poll through one path, the system shall continue to obtain health status of the RTU as well

as path status through the other path. On restoration of a failed path, system shall revert to the earlier

preferred path for polling as described above automatically without any human intervention whatsoever or

manually.

2.7 All the databases including Real time database, historic database, archive database and configuration

database shall be synchronized between Primary and Secondary Server. The interchange of health messages

between of Server shall be implemented through Local Area Network (LAN). Health status of each of the

2.8 Normally secondary server shall be in standby mode but incase operator or engineer decide to put in cold

standby mode, it should be possible to switch over standby server in cold standby mode manually when

primary is in active. Once standby server is online, the data in secondary server shall be synchronized with

active server automatically.

2.9 In case any modification or creation of new points in database, it should be possible to use the standby

server for database creation and same shall be updated in active server without any interruption or data loss.

2.10 The SCADA vendor shall have the option to implement the features of Alarm generation, association of the

synchronized to maintain database consistency.

2.13 When the SCADA Server starts up after recovery from failure, the real time and historical SCADA database

shall become identical to the active SCADA Server. The event indicating that this recovered SCADA

Server has become STANDBY shall denote that SCADA databases have been synchronized.

2.14 The failed SCADA Server on recovery if it finds itself isolated from the active SCADA Server in the Local

area network, it shall not become active SCADA Server automatically. Additionally, the active Server, if it

gets isolated from LAN (i.e. failure of both LAN connections) then it shall loss its active (primary) status

and the other SCADA Server (which is connected with the network Server) shall become active Server

automatically (i.e. implying that the disconnected Server from both LANs shall not become active

automatically). However, when the system is started for the first time, the network connectivity shall be

available and checked the SCADA Server being started first shall become active SCADA Server or by

operator choice.

2.15 For user presentation, the data source for SCADA displays, reports, trends, alarms/ events etc at HMI
