Abstract

The invention relates to a system for achieving condenser performance index on-line optimizing on the basis of a dynamic data exchange technology. The system comprises a distributed collecting systemand a condenser index on-line calculating system, wherein the distributed collecting system is used for collecting operation parameters of a condenser of a turboset in real time, and the operation parameters include the condenser circulating water inlet temperature and pressure, condenser circulating water outlet temperature and pressure, condenser vacuum and circulating flow, and steam turbine steam inlet flow; and the condenser index on-line calculating system is used for calculating the indexes of a condenser on the basis of the real-time collected condenser operation parameters and guidingoptimized operation of the condenser in real time through the calculating result. The dynamic data exchange technology is adopted and the data collecting system cooperates, on-line calculating of theperformance indexes of the condenser is achieved, the operation parameters are automatically adjusted through the calculating result, thus the condenser keeps in an optimal operation state, mistakenjudgment caused by human factors is reduced, and the operation economy of the set is improved.

Description

technical field [0001] The invention belongs to the technical field of optimizing performance indexes of wet-type cooling condensers of thermal power generating units, and in particular relates to an online optimization system for condenser performance indexes based on dynamic data exchange technology. Background technique [0002] The cold-end systems of domestic large and medium-sized thermal power plants are divided into wet cooling systems and air cooling systems. No matter which cold-end system basically has the function of online monitoring of condenser operating data, the main parameters monitored are condenser vacuum, circulating water in and out Water temperature, pressure, low-pressure cylinder exhaust temperature, hot well temperature, etc. Currently, the on-site data only stays in the monitoring function. If you want to know more about the performance index and operating status of the condenser, you must conduct a condenser performance test through a qualified th...
