摘要

针对采用大滑压储气区间的压缩空气储能系统

在储能阶段储气库压力低于末段压缩机额定/最低出口压力时

系统充气负荷由压缩机和出口调节阀协同控制的问题

搭建了某150 MW/1 200 MWh绝热压缩空气储能系统的全工况动态仿真模型。该模型基于多学科仿真建模技术

实现了热力系统动态特性与控制系统在统一平台的实时求解

在此基础上提出了多种压缩机与出口调节阀的控制策略

并对不同运行方案的调节效果进行验证。仿真实验结果表明:压缩机对流量变化的响应更敏感

在系统流量波动时始终处于调节状态;综合考虑全滑压范围内工艺系统的稳定输出和平均能效

当储气库压力低于末段压缩机额定/最低出口压力时

宜优先采用压缩机压力/压差控制与出口调节阀流量控制联合的运行方案

相较于其他方案

该方案下前三段压缩机导叶角度基本维持不变

可最大程度减少出口调节阀的节流能耗

并在储气区间中压阶段使电耗率最大降低0.30%。

Abstract

To addresses the coordinated control of the compressor and outlet regulating valve for managing the charging load in a compressed air energy storage (CAES) system with a wide sliding pressure storage range

specifically under conditions when the pressure in the air storage reservoir falled below the rated/minimum outlet pressure of the final-stage compressor during the energy storage stage

a full working-condition dynamic simulation model of a 150 MW/1 200 MWh adiabatic compressed air energy storage system was developed. Utilizing the multidisciplinary co-simulation approach

the model enabled real-time simulation of the thermodynamic system's dynamic behavior and the control system on a unified platform. Multiple control strategies for the compressor and the outlet regulating valve were proposed

and the regulatory performance of different operational schemes was verified. Simulation results indicate that the compressor responds more sensitively to flow variations and remains actively involved in regulation during system flow fluctuations. Considering both the stable output of the process system and the average energy efficiency across the entire sliding-pressure range

a combined control strategy which integrates compressor pressure/differential pressure control with outlet valve flow control is recommended when the reservoir pressure is below the final-stage compressor's rated/minimum outlet pressure. Compared to other strategies

this approach keeps the guide vane angles of the first three compressor stages essentially constant

minimizing the throttling energy loss of the outlet regulating valve

and achieving a maximum reduction in the energy consumption of 0.30% during the medium pressure phase of the gas storage interval.
