Smart Condenser in Power Generation Case Study

Smart Condenser Operations: Optimize Cooling Systems and Maximize Plant Efficiency using Pulse® Digital Twin Technology

Overview

Condensers play a critical role in maintaining the efficiency of power plants, as their performance directly impacts the overall thermal cycle. Challenges such as vacuum drops, fouling, and scaling can significantly affect the heat rate, making it essential to keep condensers operating at peak performance. Pulse's Intelligent Digital Twin (IDT) empowers power plants with real-time monitoring, early issue detection, and actionable insights to prevent performance decline and ensure optimal condenser efficiency.

Discovery

Condenser operations face challenges like fouling, scaling, and poor heat transfer, which increase turbine losses and reduce efficiency. Additionally, fluctuating turbine loads and changing ambient conditions require frequent adjustments to cooling systems, such as cooling tower fans and water pumps.

Mismanagement in these areas often goes unnoticed until significant energy losses occur. There was a strong need for a powerful system capable of detecting these inefficiencies early, identifying root causes, and optimizing operations in real-time. Pulse's Intelligent Digital Twin fills this gap, offering a smart, data-driven solution that ensures smooth and efficient condenser performance while minimizing energy losses and costs.

Condenser Discovery Process

Challenges

Condenser operations in power plants are often influenced by a variety of factors that can reduce efficiency and increase energy losses if not managed effectively. Below are some of the key challenges that need to be addressed:

  • Fouling and Scaling: These issues reduce the heat transfer ability of condensers making the system work harder and use more energy. Additionally, air leakage operations can also impact performance.
  • Sub-optimal Fan Operation: Insufficient fan operation leads to ineffective cooling or excess fan operations leading to sub-cooling conditions.
  • Auxiliary Equipment Reliability: Operating condition and health of auxiliary cooling equipment like Cooling Water Pumps and Fans.

Approach

Pulse's utilizes an AI-driven framework to track and improve condenser performance. The solutions delivered to the client were the following:

Real-Time Data Monitoring:

Pulse continuously tracks crucial parameters for condenser performance concerning varying conditions in steam flow and ambient weather conditions.

Predictive Analytics:

Pulse uses multi-variate predictive models to identify early signals of performance or reliability issues in the condenser and notify the operator.

Pulse Digital Twin Approach

Diagnostics:

Digital Twins with deep domain expertise help identify the most likely cause of the deterioration and accordingly also provide prescriptive actions.

Recommendations:

In some cases where real-time intervention helps, Pulse provides recommendations for ideal cooling tower fan operations to optimize for the cooling requirement of the plant or the right time for backwashing of the condenser if applicable.
