Benefits of technology

This patented method uses an equation called Thermal Balance Compensation (TBC) that corrects any errors or deviations caused by factors like temperature differences between different parts inside the system's components during use. By calculating specific values based on these measurements, it can accurately determine how well the component operates at its best level without overheated or damaged due to changes made throughout their lifetime. Additionally, TBC helps optimize power usage while reducing fuel consumption. Overall, this technology allows engineers to better predict future behavior and make informed decisions about maintenance tasks.

Problems solved by technology

Technological Problem: Current methods used for calculating peak shaping capacities (PTC) are either too conservative or time-consuming because they only take measurements from specific locations within an operating range that may lead to incorrect results.

Abstract

The invention discloses a method for determining the peak shaving capacity of a heat supply unit based on actual measurement performance parameters. According to the method, actual measurement performance data (main engine actual measurement cylinder efficiency, pipeline actual measurement pressure loss, heater actual measurement end difference and the like) based on unit main and auxiliary machine operation characteristics are used, combined with a variable working condition theory of a steam turbine, through unit heat balance correction calculation, refined modeling simulation of a unit heatsupply working condition is carried out, and accurate determination of thermoelectric characteristics under the unit heat supply working condition is realized, so that peak load regulation capabilitycharacteristics under the unit heat supply state are determined, and powerful technical support is provided for power grid peak load regulation and energy-saving scheduling.
