Case Studies

25kVA Inverter

The customer wanted to overcome production challenges for the control system of the inverter such as reducing the number of wirings for interconnections, increasing in failure rate, and multiple design changes as the company were using the traditional method. Gauranga took up the challenge of the design developments in the control system followed by validations as per the customer’s requirements.

Gauranga Soft-Tech offers outsourced design, development, and support services to hardware and software companies. We excel in providing hardware and software product engineering services. Our service portfolio includes software design and development services, application management services, hardware design, and development services, and custom manufacturing services.

Alarm Multiplexor

Client’s one of the locations in Mumbai’s power generation unit has an alarm management system. In this system, Alarms from various parts of the plants are consolidated at various different servers and displayed on multiple screens to form a control room where decisions are taken based on the information received by means of alarms. In order to revamp the old alarm multiplexor system and reduce the number of screens where the alarms are displayed, the Client decided to merge 5 server alarms to be received on one consolidated screen. The 5 systems are LCN, SER & Experion, Triconex, and MAX DNA systems.

ENE-Box Johnson Controls Android Application

The customer was in need of an Energy Monitoring/ Reporting utility that would be placed on-site to monitor the energy usage based on the Utility Type and other monitoring parameters. This application is needed to be user-friendly and accessible; hence this is being built for the Android Tablet Environment. The tablet would be interacting with the Metasys System which communicates based on BACnet Protocol. The tablet would be communicating with Metasys using Bacnet to pull all the required information for the reporting and mapping of the energy points in the building.

Lamination Machine Controller

The customer wants to microcontroller-based solution, which will eliminate the relays and contractor logic, and offer a touchscreen display to the user. This involves precise temperature controlling of two sets of rollers, with PID algorithm, motor control operations for the laminations, interfacing other safety sensors such as laser for hand detection, etc. Temperature measurement of the roller should be contactless IR sensing. The customer also wants to have different statistical data on the touch screen and has different configuration settings.

MVB Interface for 3x130KVA

The MVB bus stands for Multifunction Vehicle Bus, is used in railways to interconnect equipment of a consist. This bus operates on a two-wire Optic Glass Fibre (OGF) cable and has a fixed data transfer rate of 1.5 Mbit/sec (Manchester II encoding). The bus has two major components for communication, viz. Process Data is used for cyclic data circulation and Message Data is used for low-priority event-based communication.

The Client, in the process of enhancing its product portfolio, was in the new development of an auxiliary 3x130KVA converter project, for which they needed help in implementing the message data component of the MVB protocol, while the process data component was implemented by a third party. The process data component was implemented with a hardware unit that only processed data compliant, so the requirement also included identifying a hardware component that will enable the system to be message data compliant. Also, there was the unavailability of appropriate documentation from the Railways so the task expected to re-engineering the locomotive’s MVB communication with the existing auxiliary converter and thus identifying the packets to be sent by the new auxiliary system.

Solar 4G IOT logger

The customer wants to develop a 4G IOT logger, specifically for solar rooftops, which will be cost-effective and customizable. Some Industries operate solar plants along with diesel generators (DG), in that case, the solar plant generation has to be adjusted according to the load demand. Reverse flow to the DG should be avoided. Apart from this, there are some customers, who are yet to obtain grid export permission. For such customers, the solar plants will be operated, but, will produce only the much required for the load, and don’t allow any grid export. Apart from this, the logger should need to post the data to the cloud and should have an array of digital and analog inputs, USB expansion ports, Ethernet communication ports, isolated RS485 ports, etc. The device should also have the facility of talking multiple protocols to communicate with field inverters and other solar devices.
