This disclosure relates to systems and methods for tuning combustion dynamics in a combustor. In one embodiment of the disclosure, a method includes providing, via at least one sensor, combustion dynamics amplitude data associated with a combustor. Method may allow monitoring, by an equipment controller communicatively coupled to the at least one sensor, the combustion dynamics amplitude data. Themethod may allow detecting at least one change in acoustic pressure amplitude associated with combustion in the combustor. In response to detection of the change in the acoustic pressure amplitude, the method proceeds with determining a fuel split change to at least two fuel circuits configured to supply fuel to the combustor, and applying the fuel split change to the combustor. 本发明涉及用于调谐燃烧器中的燃烧动力的系统和方法。在本发明的个实施例中，种方法包括通过至少个传感器提供与燃烧器相关联的燃烧动力振幅数据。方法能够允许通过以通信方式连接到所述至少个传感器的设备控制器监测所述燃烧动力振幅数据。所述方法能够允许检测与所述燃烧器中的燃烧相关联的声压振幅的至少个改变。响应于检测到所述声压振幅的所述改变，所述方法继续确定被配置成将燃料供应到所述燃烧器的至少两个燃料回路的燃料分离改变，并将所述燃料分离改变应用于所述燃烧器。
