[0051] Example 2

[0052] like Figure 1As shown, the high-emission temperature control method for energy storage generator sets provided by the present invention includes:

[0053] The first step is to calculate the actual control value of the target high exhaust temperature 030. When the automatic mode 003 of the high exhaust temperature loop of the energy storage generator set is 1, the output is the given high exhaust temperature 001 of the energy storage generator set. When the automatic mode 003 of the high exhaust temperature loop of the energy storage generator set is 0, the output is the actual high exhaust temperature 002 of the energy storage generator set.

[0054] The second step is to calculate the actual control value of the given high exhaust temperature 031.

When the high exhaust temperature regulation rate input 004 of the energy storage generator set is adjusted by the second limiting module 016, the high exhaust temperature regulation rate 032 is output.

[0056] The fourth step is to determine the actual working status of the high exhaust temperature regulation and maintenance 033. When the difference between the target high exhaust temperature 007 and the given high exhaust temperature 008 of the energy storage generator set is greater than 0.02, and the automatic mode 003 of the high exhaust temperature circuit of the energy storage generator set is 1, and the high exhaust temperature regulation button 005 of the energy storage generator set is 0, then the final output high exhaust temperature regulation and maintenance 033 is 1.

[0057] The fifth step is to determine the actual working status of the high exhaust temperature regulation function 034. When the high exhaust temperature regulation function button 005 of the energy storage generator set is 1, the final output of high exhaust temperature regulation function 034 is 1.

[0058] Example 3

[0059] like Figure 2As shown, through the implementation and application of the technology of this invention within the simulation range (specifically, within 0 to 6000 minutes), during the entire high-discharge temperature regulation process, without the use of this technology, the high-discharge temperature of the energy storage generator set increased too rapidly within the time range of 0 to 1000 minutes, severely affecting the stable operation of the energy storage generator set. After the implementation of this technology, it can be observed that the rate of increase of the high-discharge temperature curve after adjustment is well controlled, and its rate of change is stable. It will not cause accidental operating conditions due to sudden temperature rises or drops, thus ensuring the safe and efficient operation of the energy storage generator set.
