【Abstract】 Industries such as compressed air energy storage raise critical requirements on operation ranges of pressure ratio and mass flow of compression systems. Multi-compressor series-parallel design is adopted to achieve safety and stability under complex operation conditions, and accurate prediction and controlling strategies of system aerodynamic matching faces great challenges. A through-flowbased matching analysis method of multi-compressor series-parallel compression systems is proposed in this paper. The prediction models are established based on an in-house two-dimensional throughflow tool of axial compressors, coupling through-flow calculations with one-dimensional characteristics of pipe components The quasi-steady matching performances of the compression system can be analyzed for loading and start/stop processes. For a specific preliminary design of the multicompressor series-parallel system, matching analysis is conducted for operation windows and the start/stop process under varied operation modes. The impact mechanisms of controlling strategies such as bypass bleeding and IGV opening are discussed on the start/stop characteristics and matching performances. This study provides an enhanced and reliable method for the design, analysis and operation of multi-compressor systems更多还原
