Enterprise Protection Information System EPIS

The Intelligent Lifecycle Management Platform for Protective Relays and IEDs

 

Modern power grids demand more than a relay database. IPS®EPIS is the enterprise-grade software platform that manages the complete lifecycle of your protective relays and Intelligent Electronic Devices, from the initial change request through development, approval, commissioning, and final verification. Designed for transmission and distribution utilities, EPIS ensures the highest levels of power system security, reliability, and regulatory compliance.

Enterprise Protection Information System

A Unified Platform for Protection Asset Intelligence

EPIS provides a digital twin of your protection assets, creating a single, authoritative source of truth for all relay and IED data across your enterprise. Our platform goes beyond simple inventory management to deliver deep, component-level visibility into every device in your protection scheme.

As a core module within the Grid Operation Support portfolio, EPIS is natively integrated with our CIM-based Network Model Management (NMM) solution, ensuring relay settings are always aligned with your network’s actual topology. This integration eliminates the dangerous gap between the network model used for protection studies and the settings deployed in the field.

Core Capabilities of the Enterprise Protection Information System

Full lifecycle and workflow management

Full Lifecycle and Workflow Management

EPIS manages the complete relay settings and configuration lifecycle through a structured, configurable workflow engine. Every change request is initiated, tracked, reviewed, approved, and verified within the system. Role-based access controls ensure that only authorized personnel can modify critical protection parameters, and a comprehensive audit trail records every action taken, providing an irrefutable record for compliance and post-event analysis.

Native Integration with Network Model Management

The native integration between EPIS and Network Model Management (NMM) is a defining capability of our solution. The NMM serves as a central repository for the CIM-based network model, importing data from engineering tools such as CAPE and SCADA systems. EPIS consumes this model to ensure that relay settings are always calculated and verified against the correct network topology, for both current conditions and planned future configurations. This integration directly addresses one of the most significant sources of protection of miscoordination in modern utilities.

Extensive vendor-agnostic relay and IED library

Extensive Vendor-Agnostic Relay and IED Library

Our continuously updated master-type library includes detailed data models for protective relays and IEDs from all major manufacturers, including SEL, GE (GE Vernova), ABB (Hitachi Energy), Siemens, Schneider Electric, and many others. This vendor-agnostic approach means your protection team can manage your entire mixed fleet of devices, regardless of manufacturer, from a single, unified dashboard.

NERC PRC Compliance and Regulatory Reporting

EPIS provides comprehensive support for NERC PRC regulations, including PRC-023 (Transmission Relay Loadability), PRC-025 (Generator Relay Loadability), PRC-026 (Relay Performance During Stable Power Swings), and PRC-027 (Relay Loadability). The system automates the generation of compliance reports, tracks maintenance activities against PRC-005 requirements, and provides alerts for upcoming compliance deadlines. When a NERC audit occurs, your compliance team can produce the required documentation in minutes rather than days.

NERC PRC compliance and regulatory reporting
Support for the IEC 61850 and IEC 61970 standards

IEC 61850 and IEC 61970 Standards Support

As the industry transitions to digital substations based on IEC 61850, EPIS supports it as Configuration Item Management, including file management
+ life-cycle attributes such as Configuration Item Family, Configuration Item Type, Configuration Item Status, Version. The system’s CIM-based architecture aligns with IEC 61970, ensuring seamless interoperability with other utility systems and future-proofing your investment as standards continue to evolve.

Component-Based Digital Asset Modeling

Our platform enables detailed modeling of digital assets through a hierarchical, component-based structure. Each relay or IED can be decomposed into its individual components, hardware modules, software versions, firmware, communication interfaces, and managed independently. This granular visibility supports proactive maintenance, vulnerability management, and precise version control, providing the foundation for a true digital twin of your protection infrastructure.

Enterprise-Wide Protection Coordination Process

EPIS supports the enterprise-wide area-protection coordination process, enabling protection engineers to manage and verify coordination among relays across different substations and voltage levels. By integrating protection data with the network model, the system enables evaluation of relay settings under current and future network conditions, reducing the risk of miscoordination and improving overall system reliability.

Measurable Outcomes for Your Utility

The value of EPIS extends beyond operational efficiency. It directly impacts the reliability of your grid, the safety of your workforce, and the financial performance of your utility.

Reduced Risk of Protection Misoperation

By ensuring that relay settings are always accurate, current, and aligned with the network model, EPIS directly reduces the risk of relay misoperations, one of the leading causes of major grid disturbances.

Accelerated compliance readiness

Accelerated Compliance Readiness

Automated reporting and a comprehensive audit trail transform NERC PRC compliance from a reactive, labor-intensive exercise into a proactive, continuous process. Utilities report significant reductions in the time and resources required to prepare for regulatory audits.

Improved engineering productivity

Improved Engineering Productivity

Automatic data import from engineering tools, standardized test templates, and automated report generation frees your protection engineers from administrative tasks, allowing them to focus on high-value engineering work.

Faster response to network changes

Faster Response to Network Changes

When network topology changes, due to maintenance, fault response, or planned upgrades, EPIS provides the data and workflow tools to rapidly evaluate and update protection settings, minimizing the window of vulnerability.

Cybersecurity by design

Enhanced Cybersecurity Posture

Role-based access controls, a complete audit trail, and support for NERC CIP-related IED management practices contribute to a stronger cybersecurity posture for your critical infrastructure.

Frequently asked questions

EPIS utilizes a bidirectional, native integration with the Network Model Management (NMM) module. It maps CIM (IEC 61970) topology data directly to protection zones. When a network topology change occurs, the system flags affected relays and can trigger a re-evaluation of settings against the updated short-circuit model imported from engineering tools like CAPE or Aspen OneLiner, ensuring protection schemes remain valid.

The workflow engine is pre-configured to support PRC-027-1 compliance by automating the tracking of the 72-month wide-area coordination study intervals. It triggers alerts when studies are due, links the approved coordination study documentation directly to the specific relay settings applied in the field, and maintains an immutable audit trail of the engineering approvals and implementation dates.

Absolutely. The component-based digital asset model allows engineers to track specific firmware versions down to the individual communication or processing module within an IED. When a vendor issues a security advisory or firmware patch, you can instantly query the database to identify all affected devices across the enterprise and initiate a bulk change-management workflow to apply the patch.

EPIS features a robust master-type library with native parsers for proprietary vendor formats, including SEL (.rdb, .txt), GE (.urs). It extracts the raw setting values and maps them to a standardized, vendor-agnostic data model for enterprise-wide reporting and comparison, while still retaining the original native file as an immutable attachment for direct upload back to the relay.

Yes. Through the IPS® Relay Expert (RELEX) module, protection engineers can define standardized, template-based calculation formulas. The system can automatically pull line impedances, CT/PT ratios, and fault currents from the integrated network model to populate these formulas, significantly reducing manual calculation errors and standardizing protection philosophies across the grid.
