The invention discloses an online real-time test method and an online real-time test device of turbine unit running heat consumption rate. The online real-time test method of the turbine unit runningheat consumption rate includes: obtaining main steam flow parameters and reheat steam flow parameters; confirming main steam flow according to the main steam flow parameters by using the Flugel formula; confirming reheat steam flow according to the reheat steam flow parameters by using the Flugel formula; confirming net heat input of turbines according to the main steam flow and the reheat steam flow; obtaining power of generators of the turbines; confirming the heat consumption rate of a turbine unit according to the net heat input of the turbines and the power of the generators. By using theonline real-time test method and the online real-time test device of the turbine unit running heat consumption rate, high accuracy heat consumption rate can be obtained online in real time.
Description
Technical field [0001] The invention relates to the field of thermal power generation, in particular to an online real-time test method and device for the operating heat consumption rate of a steam turbine unit. Background technique [0002] The steam turbine is one of the main equipment of thermal power plants, and the heat consumption rate is the most important indicator reflecting the economic performance of the steam turbine unit. There are usually two methods to obtain this index: one is the test method, that is, under specific operating conditions, through the unit performance test means, the measurement of dozens of parameters, the use of steam turbine side regenerative system balance calculation, and finally obtain Unit test heat consumption rate; the second is the online method, which is mainly used in the Safety Instrumented System (SIS) of the plant-level monitoring information system and the steam turbine operation optimization system developed by some professional un...
