SCADA for electrical utilities refers to the use of supervisory control and data acquisition systems to monitor, manage, and control electrical infrastructure such as substations and distribution networks. Applications can range from localized HMI SCADA systems in substations to centralized control rooms overseeing larger electrical networks.

iPower for Proficy is purpose-built for electric utility operations. It extends Proficy iFIX or CIMPLICITY with real-time data communication, dynamic data displays, alarm and event management, and secure operator supervisory control. Its scalable architecture supports applications ranging from individual substations to larger, multi-server utility control rooms.

In power grids, SCADA systems provide monitoring and supervisory control of substations, breakers, transformers, IEDs, and other field equipment. They collect real-time data from remote devices and present operating conditions to control room personnel, helping operators identify abnormal conditions and respond to issues.

These systems support the safe and reliable delivery of electricity by giving operators visibility into electrical infrastructure and the ability to monitor alarms, equipment status, and other operational information from a centralized HMI SCADA environment.

SCADA systems monitor electrical infrastructure by connecting to field devices such as breakers, switchgear, IEDs, RTUs, and other equipment and presenting real-time information through an HMI. Operators can view one-line diagrams, monitor equipment status, manage alarms, and perform authorized supervisory control actions.

iPower provides capabilities designed specifically for electrical operations, including real-time data communication, dynamic data displays, alarm and event management, control tagging, interlocks, select-before-operate control, and other tools that support consistent operator workflows.

An electric utility SCADA system typically combines several core capabilities:

Real-time communications: Connect SCADA with RTUs, IEDs, PLCs, and other electrical equipment.
HMI visualization: Present equipment status, alarms, one-line diagrams, trends, and other operational information to operators.
Supervisory control: Allow authorized operators to control electrical equipment using defined operational and safety procedures.
Alarm and event management: Identify changing or abnormal conditions and maintain records of operational events.
Historical data: Collect operational information for trending, analysis, reporting, and auditing.
Security and control safeguards: Help manage user access and support controlled operator actions.

iPower brings these capabilities together with electrical-specific tools and workflows while building on Proficy iFIX or CIMPLICITY HMI SCADA.

","title":"What are the key components of a SCADA system in an electric utility context?"},{"body":"

SCADA systems can exchange operational information with other utility, industrial, and enterprise systems using open communication standards and interfaces. This can allow organizations to connect operational data with applications used for visualization, analysis, reporting, and broader operational workflows.

iPower supports open technologies and interfaces including OPC and OPC UA, MQTT, SQL, ODBC, DNP3, IEC 61850, ICCP, and other industry protocols. This open architecture provides flexibility for connecting electrical equipment and sharing operational information with other systems.

","title":"How does SCADA integrate with other utility and enterprise systems?"},{"body":"

SCADA systems continuously collect operational data such as equipment status, measurements, alarms, and events. Providing operators with current information helps them understand system conditions, identify abnormalities, and determine when operational action may be required.

iPower combines real-time information with dynamic displays, alarm management, operator controls, and historical information to provide additional context for operational decisions. This can help operators respond more efficiently to changing electrical conditions and coordinate operational activities.

","title":"How does real-time data from SCADA systems support decision-making in utility operations?"},{"body":"

SCADA provides operators with real-time visibility into electrical infrastructure, including equipment status, measurements, alarms, and operational events. This visibility helps operators identify abnormal conditions, monitor system performance, and take appropriate supervisory control actions.

iPower adds electrical-specific control and alarm capabilities to Proficy HMI SCADA, including control tagging, interlocks, lockouts, select-before-operate control, alarm shelving, and sequence-of-events information. These capabilities help support consistent and reliable electrical operations.

","title":"What role does SCADA play in supporting reliable electrical operations?"},{"body":"

SCADA systems help utilities identify potential faults and abnormal conditions by continuously monitoring electrical equipment and field devices. Changes such as equipment trips, abnormal measurements, or other operational events can generate alarms and update equipment status within the HMI.

Operators can use this information to assess conditions and perform appropriate supervisory control actions. iPower provides alarm and event management, sequence-of-events information, one-line displays, equipment controls, and other capabilities that help operators investigate and respond to electrical system events.

","title":"How do electric utilities use SCADA for fault detection and response?"},{"body":"

SCADA can provide operational visibility into grid-connected generation and other distributed energy resources by collecting information from field devices and presenting equipment status, measurements, alarms, and other operational data to operators.

Open industrial and utility communication protocols can help SCADA systems connect with a range of electrical devices and systems. This gives operators greater visibility into connected assets and helps them monitor changing conditions within the electrical infrastructure.
