Distribution Automation Solutions

Distribution-AutomationDistribution Automation is an important component of the Smart Grid and is essential to enhance grid efficiency and reliability, reduce frequency and duration of outages, improve restoration time and cut operational costs. Distribution Automation solution is an end-to-end solution encompassing all aspects of remote monitoring, control and regulation of a utility’s distribution assets and networks.

The distribution automation solution enables real-time automated remote monitoring of key distribution utility equipment including Distribution Transformers (DT), Capacitor Banks (CB), Ring Main Units (RMU), Auto Reclosers, Sectionalizers and Fault Passage Indicators (FPI) and integrates it with SCADA/DMS systems.

Distribution Transformers (DT)

Our secure, robust and scalable SYNC 2100 series of products with in-built IO modules, wireless communication capabilities and advanced substation automation protocols are ideal for remote monitoring of DTs. DTs are critical equipment located near customer premises and help to step down the grid voltage to usable consumer levels. DT monitoring is essential to ensure reliable power supply to consumers and improve maintenance of associated devices and our SYNC2100 series enables just that. SYNC 2100 comes with the necessary IP ruggedness to withstand the elements. With embedded capabilities such as protocol conversion and low-scale data concentration, the solution is cost effective as it eliminates the need for multiple products. The solution can be customized such that it is compatible with SCADA systems and allows integration of data with distribution management systems of utilities.

Capacitor Banks

The automated capacitor bank control unit comprises the SYNC 2111/2121 feeder remote terminal units (FRTUs) and switching control mechanisms connected to three-phase capacitor banks, where the capacitor phase switches are operated by motor controlled load break switches/relays. The micro RTU switches banks and monitors reactive power and voltages of the phases, operation mode selected (auto, manual). Capacitor banks are switched based on the rules configured in the SYNC 2101 micro RTU and existing system parameters (V, KVAr). Capacitor banks are deployed in the distribution network, either within the station or across the network, and help improve the power factor of the system and thereby overall efficiency and the SYNC2111/2121 FRTUs provide the ideal support.

Ring Main Units

The SYNC 2111/2121 feeder remote terminal units (FRTUs) automate the monitoring of Ring main units (RMUs). RMUs are critical control devices in the distribution network that allow power to be supplied to consumers from alternative sources when the main source of supply fails. By allowing multi-input multi-output interconnection of the distribution network, RMUs provide redundancy and ensure reliable power supply to end consumers. Each substation will need to monitor 500-600 RMUs and manual control and monitoring of these devices will be tedious. Our FRTUs come with appropriate communication interfaces and help monitor switchgear status indicators remotely, easing the process and removing the need for manual monitoring.

Auto Reclosers and Sectionalizers

The SYNC 2100 series of intelligent remote terminal units (RTUs) provide a field interface to remotely monitor the operations of sectionalizers and auto reclosers. This data is consolidated and transmitted to the data concentrator unit at the control center to be integrated in to the SCADA /DMS operations of the utility. Autoreclosers and sectionalizers are located on the distribution network to ensure reliable power supply and helps avert permanent blackouts due to transient faults. Reclosers work in conjunction with sectionalizers. The entire distribution network is divided into different sections for ease of operations and maintenance. Remote monitoring as provided by the SYNC2100 series of RTUs is thus critical and saves time and increases efficiency.

Fault Passage Indicators

The SYNC 2100 series of intelligent RTUs enables automated remote monitoring of Fault passage indicators (FPIs) from the control center and helps in speedy restoration of power in case of outages. FPIs are installed at strategic points on the distribution network and communicate with the control center. When a fault occurs, FPIs transmit the exact position of the faulty section of the network to the control center allowing maintenance crews to be immediately dispatched to the location of the fault. This reduces the duration of blackouts and helps improve customer service.
