Solar Power Plant Management

The main Harmony SCADA dashboard displays all vital plant data with live updates and sub-second resolution.

What data is shown?

• AC and DC power per inverter
• Daily and cumulative energy
• Inverter status and temperature
• Pyranometer data (irradiance, temperature)
• Key Performance Indicators (KPIs) with custom definitions
• PR (Performance Ratio) calculation per IEC 61724

How to use

After logging in, you see the plant overview at a glance. Click any inverter for more details. Data updates with sub-second resolution.

The Harmony SCADA reporting system generates highly detailed technical, financial, and managerial reports compliant with solar power plant standards.

Output Formats

• PDF Reports: Professional visual layouts with selectable page borders (Simple, Elegant, Technical), custom project logos, and page numbering.
• Word (DOCX) Reports: Fully editable text documents styled to match corporate templates.
• Excel & CSV Outputs: Clean, structured data tables containing processed metrics for engineer-level calculations.

Analytical Sections & Features

• Key Performance Indicators (KPIs): Complete summary of Plant Availability, Capacity Factor (CF), Inverter Efficiency, and Specific Yield (kWh/kWp).
• Physics-Based Digital Twin (EPI): IEC 61724-1 compliant comparison of expected target production vs. actual production using real-time irradiance, cell temperature, DC capacity, and temp coefficients.
• Inverter Health Analysis: Thermal stress analysis (temperature vs. efficiency correlation), contribution %, and technical downtime tracking (daylight non-operational hours).
• String-Level Diagnostics & Mismatch: Peer-to-Peer Diagnostics (IEC 61724-1) comparing string currents against peer signatures to detect faults or shadowing, with visual color codes (Blue for stable, Red for critical >15% deviation warning to prevent hotspots).
• Soiling & Cleanliness Analysis: Integrates with MMS (Maintenance Management System) completed work orders to capture panel wash events, calculate PR gain before/after washing, analyze costs, and rank soiled inverters.
• Alarms Summary: Aggregated count and duration of faults categorized by severity level.

Connect to inverters via standard Modbus and SunSpec protocols. Features: variable definition, auto polling, manual read/write, remote control. Supports SMA and other Modbus/SunSpec-compatible inverters.

Single Line Diagram design with IEC 60617 symbols, smart connections, gauges and live charts. Drag & drop, multi-sheet support. Symbols link to inverters for real-time data display.

Harmony SCADA is built on HTML5 web technology. No client install, centralized updates, Canvas graphics for SLD and charts, WebSocket for real-time data. Same interface on mobile, tablet and desktop.

The integrated Harmony SCADA Maintenance Management System (MMS/CMMS) is designed to plan, track, and optimize preventive and corrective maintenance activities across the solar power plant.

Key Capabilities

• Work Orders Management: Create, edit, and track status for Preventive Maintenance (PM) and Emergency Maintenance (EM) work orders with assignments and log details.
• Equipment Health Tracking: Assess the health score of critical assets like inverters, transformers, and switchgears based on active and historical logs.
• Spare Parts & Inventory: Monitor stock levels, receive automated low-stock warnings, and track parts consumption per work order.
• Cost Accounting & Analytics: Calculate actual O&M expenses by tracking labor costs (man-hours), spare parts costs, and third-party contractor expenses.
• Upcoming Task Scheduler: Smart calendar and list of upcoming tasks (such as scheduled solar panel cleaning or annual switchgear maintenance).

Full control over requests sent to inverters and equipment. Tier-based request management for optimal speed and reliability.

Tier-based System

Poll intervals for each tier are configurable in project settings.

• Tier 1 (Critical): Vital variables like power and status — e.g. every 10 seconds
• Tier 2 (Important): Energy, temperature, main parameters — e.g. every 15 seconds
• Tier 3 (Diagnostic): Low-frequency data — e.g. every 30 seconds or more

Request Management

Request delay between reads, max requests per cycle, parallel workers for faster multi-inverter reading. Automatic prioritization for control commands.

Weather data and forecast for planning and analysis.

Pyranometer data

• Irradiance (solar radiation)
• Ambient and panel temperature
