3 The Problem - 3 -

4 The Problem Optimized Operations Measuring efficiency in Coal Fired and Combined Cycle Power Plants can be a difficult process and may require a number of departments including Management, Operations and Maintenance Multiple Data Sources To better optimize plant performance, there are a number of complex and difficult calculations, estimates and measurements that need to be configured. Gathering all this data into a single and configurable interface is difficult and error-prone - 4 -

5 The Solution - 5 -

6 The Solution Exaquantum/PPC Determines Efficiency of Plant Equipment ASME compliant power performance calculation package suitable for power generation and process plants to determine the efficiency of plant equipment Performance Calculations The performance calculations provided include the measurement and estimation of parameters for the derivation of plant efficiency and equipment heat rate calculations found in a typical power station Optimize Plant Operations Provides an indicator of the plant s operational efficiency and facilitates optimized plant operations - 6 -

7 Key Benefits - 7 -

8 Key Benefits Collects Critical Power Plant Information Powerful, integrated and cost-effective platform for collecting critical power plant information from various sources. The resulting performance information is made available across the business to users in operations, management and maintenance Optimized Efficiency Performance information can be displayed on user screens and/or Yokogawa DCS HIS stations to provide supervisors and operators with the necessary information to take corrective actions to optimize efficiency Enables Different Scenarios to be Tested What-If tool allows different input scenarios to be tested to determine the viability of cost reduction and performance improvement initiatives - 8 -

9 Key Features - 9 -

10 Features Real-Time Process Data PPC obtains real-time process data from a Process Control System(s) via an OPC DA interface making the collection of process data easy to configure and maintain A user can manually enter process data, LIMS data, etc. for use by PPC calculations Improved Power Plant Efficiency Improved power plant efficiency is achieved through continuous improvement and early diagnosis of problems. Maintenance Implemented Ideal Actual Deviation

11 Features Tag Validation Validation of tag (data point) names for erroneous entries and/or non-existent tags are clearly identified, enabling simple correction by a PPC administrator. The acquired data is also subjected to tag quality checks (Good/Bad/Uncertain including IOP) enabling calculations where the source value quality check has failed to be clearly highlighted. Expression Builder Syntax PPC includes a powerful expression equation builder to provide users with the ability to define and refine their calculations and/or constants The expression builder syntax allows for both simple and comprehensive calculation definitions Steam Table Routines Users can access steam table routines from the Expression Builder. Steam data is in accordance with IAPWS-IF

12 Features User Configurable Data Users can use Microsoft Excel to provide the following: Custom functions based on 2D or 3D curve data in order to represent, for instance, equipment performance curves, degradation curves, etc. Custom Units of Measure Once configured, the information is exported into PPC using the supplied Microsoft Excel add-in

13 Features What-If and Recalculation Capability Users can manually change input values to view the derived results to simulate the effect on plant performance This facility also allows for the correction of bad data in reports

14 Calculations

15 Calculations ASME Compliant Calculations PPC supports Coal Fired and Combined Cycle Power Plants, and is adaptable to other power plant types by incorporating ASME compliant calculations, curves, etc. to vary the plant capacity, equipment characteristics and power plant type (thermal, combined cycle, etc.). Calculation Templates Templates are provided for all power performance calculations to simplify and reduce configuration time. These templates are constantly evolving and an up-to-date list can be supplied upon request. Feed Water Heaters Boilers Steam/Water Heat Exchangers Steam Turbine Generators Gas Turbines Condensers Aggregated Process Data PPC uses aggregated process data to improve power calculations accuracy through all inputs being time coherent

16 Calculation Methods The following calculation methods are employed. Heat Loss Method Efficiency Estimation Input/Output Method Efficiency Estimation

17 Example HP Turbine Efficiency The HP Turbine Efficiency function block is used to evaluate the performance of a High pressure Turbine. The following are the required PPC Inputs with the resulting outputs (Calculations). A document is available to allow customers to assess whether they have sufficient instrumentation to satisfy the PPC input requirements
