飞轮储能型二次调节流量耦联系统研究

利用二次调节技术四象限工作原理和流量耦联系统特点，并与飞轮储能系统相集成，提出了飞轮储能型二次调节流量耦联系统。该系统可把原来系统负载下降时转化为热能散失掉的势能存储为飞轮的机械动能，并回收利用。该系统解决了传统二次调节压力耦联系统不宜接入不能变量的液压缸或液压马达的缺点，是对传统二次调节压力耦联系统的拓展。在建立了系统的数学模型的基础上，通过仿真和试验研究表明了系统的可行性，但存在快速性不高和明显非线性的特性。

Flow-coupled Secondary Regulation System Integrated with Flywheel Energy Storage

The Flow-coupled Secondary Regulation System(FSRS) integrated with flywheel energy storage was proposed based on the four-quadrants working principle of the secondary regulation technology and the characteristics of the flow-coupled system and flywheel energy system. And the potential energy could be recovered and reused using this system. It solved the disadvantage of the conventional Pressure-coupled Secondary Regulation System(PSRS) that was the fixed displacement cylinder and motor was not suitable for the pressure-coupled system. Then, the mathematical model was established of the FSRS integrated with flywheel energy storage. Finally, the simulation and experimental results show that this system is feasible. However, the nonlinear characteristics and low rapidity should be solved.
