- 2. Introduction BSES Yamuna Power Limited(BYPL), like power companies all over the world is actively looking at solutions to future proof the distribution network and make them ready for integration with smart grid transmission networks. As the only discom to have a 100% electrified area, we understand the importance of optimizing power distribution network. Strengthening and monitoring 11KV networks, we realize is the key to reduction of AT&C losses and ensuring power for all. Technology aids BYPL in managing material and manpower to monitor its network. BYPL now offers its expertise in the form of Modular Integrated Distribution Automation System (MIDAS) - the value-for-money solution in automation of 11KV/415Vdistributionnetwork. MIDAS is the result of our in-house pool of Engineers work to find solutions for predictive maintenance of networks, which allows for substantial reduction in maintenance costs while increasing reliability and quality of power supply. MIDAS allows for remote monitoring of the health of 11 KV network equipments, quick location of faults and even predicts faults prior to their occurrence. MIDAS is capable of sending auto alerts via sms. It is a cost effective, easy to use and implement solution to efficiently manage 11KV distribution grids with minimum service disruptions. 2. Distribution Transformer Unit (DT): Conveys input received from LT Palm Temperature Sensor (connected to R,Y,B line of DT, Oil Temperature sensor, Oil Level Sensor, Door Sensor) and sends it to the F R T U u s i n g R S - 4 8 5 communication. 3. RMU (Ring Main Unit): Monitors input from Isolator, Breaker, FPI, CBCT (neutral current), SF6 Gas pressure of RMU and sends it to the FRTU using RS-485 communication 4. Fault Passage Indicator (FPI): Provides visual or remote indication of a fault on the electric power system. 6. Communication medium: Modem, General Packet Radio Service (GPRS) 7. Front end web base application: Provides real time status of different substations and their corresponding parameters (sensors and meter data). FRTU Specifications To cater to ever increasing power demand, power distribution companies need to look at capacity augmentation and optimisation of their power distribution networks to eliminate bottlenecks. MIDAS has been specifically designed and developed to work at the 11KV/415V distribution substation level. So far similar SMART applications have been implemented only at 66KV grid level. On an average, rectifying distribution transformer downtime takes upto 24 hours. However, substations with predictive fault, conditioning monitoring system “MIDAS” in place, will be able to reducetheirdowntimebyapproximately85-90% Need Components Sensors Door Sensor Oil level Temperature Oil level Sensor LT Palm Temperature Sensor 1. Field Remote Terminal unit (FRTU): Indigenously developed by BYPL takes input from DT and RMU unit (sensors data), meter instantaneous parameters, fire sensor and sends it to a central server on periodic basis. 5. Core Balanced Current Transformer (CBCT): Ring type determines imbalances of transformer. • Power Requirement: Unregulated 220V+10% AC • Case: IP54/IP55 enclosure protection for Indoor Substation • IP 66/67 enclosure protection for Out Door Substation. • FRTU: Embedded hardware with 32-bit microcontroller • FRTU has internal EPROM (Erasable Programmable Read Only Memory) • Communicates with server on GPRS • RS-232/485 Interface • Flash memory of size 4 MB Functionalities • Remotely monitor • Condition of various assets such as transformer, switchgear etc • Energymeterdata(whichissentevery15min) • Fault detection in the network • Intrusion detection • Fire detection • Integration with SAP, GIS, OMS S M OSI G S AP ENERG Y AUDIT MIDAS OMS (Outage Management Solution) GIS (Geographic Information System) Benefits Features • InbuiltSMPS(Switched-ModePowerSupply) • Cost Effective • 8 AI Ports • 14 DI Ports • 8 DO Ports • Provision to integrate with smart meters • Low power consumption • Designed to work in harsh environment Predicting fault and Condition Monitoring: With the advantage of fault prediction discoms can take corrective actions in time which will translate to: • Reduced physical theft • Protection against fire • Lower effort • Reduced maintenance cost • Reduced downtime of equipment • Extension of equipment service life • Improved support for operations, maintenance andprotectionengineersand • Provide sustainable investments to future- proof 11KV network For the customer, implementation of MIDAS by a discom translates to higher reliability and availability of power.
