Description

Technical Field

[0001] The present invention belongs to the field of intelligent control of generator sets, and particularly relates to a control method and system for the adaptive operation of the main steam pressure of an energy storage generator set under various working conditions. Background Art

[0002] The adaptive operation of the main steam pressure of an energy storage generator set under various working conditions is a complex process involving multiple technical aspects, requiring in-depth understanding and precise control of the operating characteristics of the unit, load demand, and the performance of the energy storage system. The following are some key considerations for the adaptive operation of the main steam pressure of an energy storage generator set under various working conditions: 1) The main steam pressure and temperature are key parameters affecting the operating efficiency and safety of the steam turbine. During the commissioning process, it is necessary to ensure that the pressure and temperature of the main steam match the design values of the unit to avoid efficiency reduction or equipment damage caused by parameter deviation from the design values.

[0003] 2) When the main steam pressure increases, although the steam flow rate will decrease to some extent, it is necessary to pay attention to preventing problems such as overloading of the unit and overloading of diaphragms and moving blades. On the contrary, when the main steam pressure decreases, it is necessary to increase the steam flow rate to maintain the rated power, which is extremely likely to cause an increase in the load of each stage of the non-regulation stage and even the problem of overloading.

The control system for adaptively putting into operation the main steam pressure of the energy storage generator set under various working conditions according to claim 8, wherein, It also includes that the power being greater than 10% of the rated power (012) is connected to the seventh non-module (030).

10. Control method for adapting and putting into operation the main steam pressure of a energy storage generating unit under various operating conditions, characterized in that, The method is based on the control system for the operation adaptation of the main steam pressure of the energy storage generator set according to claim 9, and includes: In the first step, judge the actual working state of the main steam pressure protection input (034) of the energy storage generator set. When the main steam pressure (001) of the energy storage generator set meets the preset value of the first greater comparison module (013), and the main steam pressure limit setting value error (002) is 0, and the main steam pressure limit protection input (003) is 1, the main steam pressure being less than the low limit value of the main steam pressure (004) is 0, and the main steam pressure being greater than the high limit value of the main steam pressure (005) is 0, then the main steam pressure protection input (034) of the energy storage generator set is 1. This state indicates that the main steam pressure protection of the energy storage generator set has been input, and the change of the main steam pressure can be monitored comprehensively at any time; In the second step, judge the actual working state of the main steam pressure protection input permission (035) of the energy storage generator set. When the main steam pressure (001) of the energy storage generator set meets the preset value of the first greater comparison module (013), and the main steam pressure limit setting value error (002) is 0, then the main steam pressure protection input permission (035) of the energy storage generator set is 1; when the main steam pressure being greater than the high limit value of the main steam pressure (005) is 0, or the main steam pressure being less than the low limit value of the main steam pressure (004) is 0, or the energy storage generator set being disconnected (006) is 0, or the main steam pressure limit protection being withdrawn (007) is 0, or the steam turbine having tripped (008) is 0, or the main steam pressure channel failure (009) is 0, then the main steam pressure protection input permission (035) of the energy storage generator set is 1; In the third step, judge the actual working state of the main steam pressure limit action (036) of the energy storage generator set. When the main steam pressure being greater than the high limit value of the main steam pressure (005) is 1, then the main steam pressure limit action (036) of the energy storage generator set is 1. This state will limit the change of the main steam pressure of the energy storage generator set to ensure the safe and stable operation of the unit.
