【摘要】：在当今电力消耗量持续增长的同时,化石燃料燃烧所导致的严重污染使得能源与环境的矛盾日益凸显。可再生能源电力在电力供应中的份额势必要加重,但是可再生能源的引入会增加目前电力系统的复杂性及不安全性。研发高效、清洁的储能技术是解决可再生能源电力发展瓶颈问题的关键。本文首先利用热力学理论知识分析了等温压缩空气储能的原理,提出了基于蓄液单元和蓄气单元的液体活塞专利技术,确定了等温压缩空气储能系统温控的实现方案。结合直线电机直线往复运动的特性以及抽水蓄能发电效率高、技术成熟的优点,提出液体活塞通过液压传动机构与直线电机直连和与虚拟抽水蓄能装置连接两种储能方案。对等温压缩空气储能系统通过液压传动机构与永磁直线电机直连的储能方案进行仿真。分别研究了系统储能和发电阶段的控制策略,在MATLAB/SIMULINK中建立了储能阶段和发电阶段的系统仿真模型,进行仿真研究,仿真结果验证了方案及控制策略的可行性。对等温压缩空气储能系统通过液压传动机构与虚拟抽水蓄能装置连接的储能方案,分别就发电过程和储能过程进行分析,并结合实例进行了详细计算分析。对永磁直线电机进行控制系统仿真,仿真结果验证了方案的可行性。最后,对本文提出的直线电机应用于等温压缩空气储能的两种方案进行总结,分析各自应用领域,对未来等温压缩空气储能系统研究工作的重点及直线电机在等温压缩空气储能领域中的应用进行了展望。
[Abstract]:In today's electricity consumption continued to grow at the same time, the serious pollution caused by combustion of fossil fuels makes the contradiction between energy and the environment has become increasingly prominent. Renewable energy power in the power supply of the share is bound to increase, but the introduction of renewable energy will increase the complexity of the power system and safety. To develop an efficient and clean storage. Technology is the key to solve the bottleneck problem of the development of renewable energy power.
This paper first analyzes the principle of isothermal compressed air energy storage based on the theory of thermodynamics, and puts forward the patent technology of liquid piston based on liquid storage unit and storage unit, and determines the realization plan of the temperature control of the isothermal compressed air energy storage system.
Combined with the characteristics of linear reciprocating motion of linear motor, and the advantages of high efficiency of pumped storage and mature technology, two energy storage schemes of liquid piston connected directly to a linear motor and a virtual pumped storage device are put forward.

The control strategy of the system of energy storage and power generation stage respectively, established in MATLAB/SIMULINK simulation model of energy storage system stage and power generation stage, simulation research, the simulation results verify the feasibility and scheme control strategy.
Isothermal compressed air energy storage system through the hydraulic transmission mechanism and virtual water pumping device connected storage solutions to energy storage, power generation and storage process respectively, process analysis, and gives an example of the detailed calculation and analysis. The simulation of control system of permanent magnet linear motor, the simulation results verify the feasibility of the scheme.
Finally, the two schemes of linear motor based on isothermal compressed air energy storage are summarized, analyzed their application areas, focus on the future of isothermal compressed air energy storage system research and the work of the linear motor in the isothermal compressed air energy storage applications in the future.
