本研究结果总结如下：1。采用可控直流电源构建了带整流器的FC模拟器，并对其进行了测试，验证了所构建FC模拟器的有效性。FC并网逆变器的研制FC并网逆变器采用基于dsp的控制系统，作为电力线调节器。因此，平衡和正弦源电流通过FC.3产生直流功率。FC发电系统家庭用电剩余电量的确认我们已经证明，当家庭用电电量发生突然变化时，存在剩余和亏缺电量。由于日本电力法规不允许FC发电系统将其产生的电力注入电力系统，因此需要抑制剩余电力。从而确定了飞轮发电机的转动惯量。在PSIM软件上构建了直流电机驱动系统的飞轮模拟器，其中直流电机驱动系统作为飞轮。转动惯量是可控的。因此，所构建的飞轮模拟器适用于各种家庭使用。以一个典型的日本家庭为背景，构建了一个带有飞轮发电机模拟器的FC发电系统。在家用FC发电系统中，负荷条件发生了突变。因此，如上所述，存在着盈余和赤字权力。通过数字计算机仿真，证明了飞轮发电机能很好地抑制FC发电系统产生的富余和亏缺功率。根据美国能源部的发展计划，到2010年，重整器的响应时间将少于25秒。这意味着EDLC可以用来抑制剩余和亏缺功率。因此，我们开发了一个家庭使用的EDLC模拟器。少

The summary of this research results is as follows:1. Development of the FC simulator with a reformer The FC simulator with a reformer has been constructed using a controllable dc power supply, and tested to demonstrate the validity of the constructed FC simulator.2. Development of the grid-connectable inverter for the FC The grid-connectable inverter for the FC has been constructed with a DSP-based control system, where the inverter acts as a power line conditioner. Thus the balanced and sinusoidal source currents are obtained generating the dc power by the FC.3. Confirmation of the surplus power in the home uses of the FC generation system We have demonstrated that the surplus and deficit power exits when the consumed power in a home is suddenly changed. Suppressing the surplus power is needed because the injection of the power generated by the FC generation system to power systems is not permitted by Japanese low. Thus the moment of inertia of the fly-wheel generator is decided.4. C … More onstruction of the fly-wheel generator The fly-wheel simulator with the dc motor drive system has been constructed on PSIM software, where the do motor drive system acts as a fly-wheel. The moment of inertia is controllable. Thus the constructed fly-wheel simulator is useful for various home uses.5. Construction of a FC generation system for home uses A FC generation system with a fly-wheel generator simulator has been constructed considering a typical Japanese home. In home uses of the FC generation system, the load conditions are suddenly changed. So the surplus and deficit power exists as described the above. We have demonstrated that the surplus and deficit power generated by the FC generation system are perfectly suppressed by the fly-wheel generator by digital computer simulation.6. Development of a EDLC simulator According to the development plan of the DOE, the response time of a reformer will be less than 2s by 2010. This means that an EDLC can be used to suppress the surplus and deficit power. Thus we have developed an EDLC simulator for home uses. Less
