SUB-STATION AUTOMATION

power

Basically to fully leverage the investment in a modern substation automation system, customers need a solution with advanced product and domain expertise across the enterprise to fully extract the value of the investment in time and resources.

For overall asset management and optimization strategies, network operators are looking more opportunities for monitoring and management of substation asset. Now training regimes are heading to a significant reduction in user costing performance, at the lower total cost of ownership while also providing both communications network integration and data security.

For reduction in the cost of total life cycle demands the systems conception and the design of each element for integration, installation and maintenance /operation from the outlet. This includes effective and efficient configuration tools and testing systems.

It has become a challenge to manage all aspects of increasingly complex substation automation systems for customers like utilities and Industrial.

Our system is capable to communicate all make of IED’s over IEC 61850.

HYDRO-TURBINE CONTROL SYSTEM

“We have developed a system using 2 Nos. of Micro Logix 1400 PLC (Allen Bradley) & One SLC 5/05 hardware & PLC (RS Logix 500) & SCADA (Factory Talk View SE) software. System is highly rugged, flexible & cost effective.”

Challenge

To develop a system for data monitoring from Governor, Protection Relays, Energy Meters. That has been achieved very well by our existing PLC based system.

Solution

Developed a highly rugged, flexible & cost effective. Read the data from Governor, Protection Relay, Energy Meters on Modbus network on 3 PLC’s & all the PLC’s are inter-connect on Ethernet Network.

Also develop the 14 SCADA display.

What is Governor?

Governor is commonly used to control the Turbine unit. Hydro turbine governor is one of the important auxiliary equipment’s in a hydroelectric generating set, a general term that describes one or more devices consist of realizing adaptive water-turbine and responsive control mechanism and indicators

What is Protection Relay?

A protective relay is a relay, the principal function of which is to protect service from interruption or to prevent or limit damage to apparatus. In electrical engineering, a protective relay is a device designed to trip a circuit breaker when a fault is detected

System Configuration

The system, which we created for HYDRO TURBINE CONTROLING consist of Compact Logix Series for feedback and controlling , One Micrologix 1400 used for Reading the Temp. data & Governor-1 Data & Second Microlox 1400 used for reading the Governor-2 Data,4- Multi Function Energy Meters,2- Protection Relays  & others logic. SCADA System  was developed to have data logging , controlling and visualizing all important and desirable parameters at a glance.

System Implementation

We implemented the entire system within 10 man-days. User friendly Allen Bradley software &

Hardware helped us to complete system in such short time.

Our new test system based on AB hardware’s and RS LOGIX 5000 software is highly flexible, rugged, and cost-effective.

Vibration Module

“We have developed a system using Allen Bradley PLC, Vibration Module, Accelerometers ( Both contact and non-contact type), Panel View Plus 6 HMI (Allen Bradley) hardware & RSLogix 5000, Factory Talk View Studio software. System is highly flexible & cost effective, Each module measures and reports the overall vibration level between selected high and low pass filters, as well as gap or bias voltage for each channel & we guarantee measurement accuracy within ± 2 microns”.

 Challenge

To develop a system for accurate measurement overall vibration level between selected high

and low pass filters, as well as the gap or bias voltage for each channel & measurement accuracy within ± 2 microns.

Solution

Developed a highly flexible & cost effective, designed for real time monitoring of overall (direct) vibration levels & we guarantee measurement accuracy within ± 2 microns with Allen Bradley world class Automation control system.

System Configuration

The Direct Vibration modules are intelligent 6-channel monitors that are designed for real time  monitoring of overall (direct) vibration levels. Each module measures and reports the overall vibration level between selected high and low pass filters, as well as the gap or bias voltage for each channel. The module can power and accept input from Integrated Electronics Piezo Electric (IEPE) accelerometers. They can also accept signals from standard eddy current probe systems and most standard voltage output measurement devices such as a velocity or pressure transducer making them well-suited for general machine monitoring and protection.

The vibration module includes six 4-20mA output channels. The 4-20mA outputs are arranged into two isolated banks of three outputs each. Each bank of 4-20mA outputs is electrically isolated from the other bank and from circuit power and ground. The isolation provided is up to 250V. The Direct Vibration Modules can accept input from any Allen-Bradley non-contact eddy current probe, a standard IEPE accelerometer, a velocity transducer, or AC voltage output measurement device. The vibration modules require a dedicated 24V dc power supply or an isolated 24V dc power supply wired in reverse to power a standard 24V non-contact eddy current probe driver. You can use the Allen-Bradley 1606-series power supply for this purpose. The vibration modules requires an external DC power supply to provide loop power.

To determine the minimum voltage across the total loop, add the resistance of all loads in the loop. Wire the loop-powered 4-20mA connection to the terminal base unit of the XM-161. A 250 ohm resistor is the recommended load.

The system uses the MicroLogix 1400(PLC) for controlling the entire process & Panel View

Plus 600(HMI) to monitor the status of Vibration Monitoring System for particular unit.

System Implementation

We implemented the entire system within 4 man-days. User friendly Allen Bradley software &

Hardware helped us to complete system in such short time.

The IEPE Power in the vibration module is configurable in channel pairs: Channels 1 and 2, Channels 3 and 4, and Channels 5 and 6. When you have different transducer types, such as an IEPE accelerometer and a non-contact sensor, the non-IEPE powered transducers cannot be in the channel-pair with the IEPE transducer. For example, when you are connecting a single IEPE accelerometer and a single non-contact sensor to the vibration module, wire the accelerometer to channel 1 and enable the IEPE Power Channels 1 and 2 parameter. Wire the non-contact sensor to channel 3 and disable the IEPE Power Channels 3 and 4 parameter.

A special cable  is required for this serial connection. The connector that inserts into the PC is a DB-9 female connector, and the connector that inserts into the module is a USB Mini-B male connector.

The Direct Vibration Modules can accept input from any Allen-Bradley non-contact eddy current probe, a standard IEPE accelerometer, a velocity transducer, or AC voltage output measurement device. The vibration modules require a dedicated 24V dc power supply or an isolated 24V dc power supply wired in reverse to power a standard 24V non-contact eddy current probe driver. You can use the Allen-Bradley 1606-series power supply for this purpose. The system carries out the overall vibration level between selected high and low pass filters, as well as the gap or bias voltage for each channel which is displayed on the Panel View Plus 6(HMI).
