Introduction

Description

The Event Log Widget is designed to display alarms and events generated by assets in renewable energy operations. It provides a structured view of event data, including event descriptions, priority levels, and calculated properties. Users can filter events to limit results to those relevant to a particular use case. Events can be grouped by event code or parent asset to streamline analysis and response workflows.

Purpose

This widget helps operations and maintenance teams monitor asset health and respond to critical events efficiently. By centralizing alarms and event data, it supports fault tracking, performance diagnostics, and compliance reporting across Solar, Wind, and Battery Energy Storage Systems (BESS).

Target Audience

Business Users: Operations managers, asset owners, and compliance officers who need visibility into asset-level events and alarms.
Technical Users: Engineers, analysts, and system integrators responsible for configuring event monitoring and diagnostics in dashboards and reports.

Key Features & Use Cases

1. Event Grouping

Group events by event code, parent asset, or other metadata to simplify navigation and analysis.

Use Case – Wind Farm Fault Tracking
An operations manager groups turbine fault events by event code to identify recurring issues across multiple turbines, enabling targeted maintenance planning.

2. Event Details

Each event entry includes a description, priority level, and calculated properties such as duration, frequency, or impact.

Use Case – BESS Alarm Monitoring
A dashboard displays battery system alarms with priority levels and calculated downtime energy losses, helping teams prioritize high-risk issues.

3. Filtering & Sorting

Users can filter events by time range, asset type, priority, or event category to focus on relevant data.

Use Case – Solar Site Compliance Review
A compliance officer filters the event log to show only high-priority inverter alarms from the past 30 days, supporting audit documentation.

4. Real-Time & Historical Views

Supports both real-time event monitoring and historical event analysis for trend identification and reporting.

Use Case – Fleet-Wide Event Analysis
An analyst reviews historical fault events across multiple solar sites to identify patterns and recommend system upgrades.

Data Types Used

The Event Log Widget uses structured event data, typically including:

Timestamp – When the event occurred.
Event Code – Identifier for the type of event or alarm.
Asset – The asset that generated the event (e.g., turbine, inverter, battery module).
Description – Textual explanation of the event.
Priority Level – Severity rating (e.g., status, warning, alarm).
Calculated Properties – Derived metrics such as event duration, frequency, or energy loss.

These data types support both operational monitoring and strategic analysis across renewable energy assets.

Widget Use in BI App Types

Use in Dashboards

In dashboards, the Event Log Widget provides real-time visibility into active alarms and recent events. It helps operations teams respond quickly to faults and monitor asset health across sites.

Example – Solar Operations Dashboard
A dashboard displays inverter alarms grouped by event code, with priority indicators and calculated downtime. This enables fast triage and dispatch of maintenance crews.

Use in Reports

In reports, the widget supports historical event analysis and compliance documentation. It helps stakeholders review past incidents, assess asset reliability, and support regulatory reporting.

Example – Quarterly BESS Fault Report
A report includes a filtered event log showing all critical battery system alarms over the past quarter, grouped by asset and summarized by frequency and impact.
