Firstly, the transient stability of the modes by which some kinds of huge power suppliers are connected with AC power grid is analyzed and compared in detail; then a detailed transient stability simulation of a certain large-scale demonstration system is performed; finally some helpful conclusions are obtained: in the general situation, the bundling power transmission mode is favorable to increase the stability of sending system; if it is helpful to evidently increase the inertia of the equivalent leading group, the mode that connects the huge power supplier with sending system will be helpful to enhance the stability of sending system, however it is necessary to perform simulation and analysis while these principles are applied to FACT systems.

首先从机制上对几种大电源接入交流系统方式的暂态稳定性进行了详细的分析和比较；然后对大型算例系统进行了详尽的暂态稳定仿真；最终得出了一些有用的结论：一般情况下，打捆送电方式有利于提高送出系统的稳定性；如果有助于显著增加领前群的惯量，则与送端系统相联的方式也有助于提高送电系统的稳定性，但仍要结合具体系统进行分析。

But disconnect the load and the output correctly, in the time, I fail to understand why it suddenly occurred to power does not output voltage may also be due to eircuit the power protection, since switching power supply does not have the problem, according to the circuit diagram check switching power supply external power supply module one by one, if the hinge-counter, discovered its signal line wrap wire close to counter one end of the triadha into the signal lines, causing a short circuit input line.

可是断开负载，其输出正常，在百思不得其解之时，笔者突然想到电源不能正常输出电压也有可能是由于负载短路使电源保护造成的，既然开关电源本身没有问题，按照电路图检查开关电源外围的供电模块逐一排查，当检查到折页计数器时，无意中发现其信号线外缠绕的钢丝线接近计数器的一端扎进了信号线中，造成输入线短路。

The definition of instantaneous reactive power in sinusoidal circuit is still a pending problem and should be studied further. The authors consider that the theory of instantaneous power should be studied on the basis of the original definitions of instantaneous active and reactive power.

针对研究近一个世纪还没有解决的瞬时无功功率界定与定义的问题，该文认为应从原始瞬时有功功率、瞬时无功功率界定来研究瞬时功率理论。

Using solar cell to absorb solar energy and store into battery by DC-DC charger during daytime. When in the night, battery will be discharged to white LED by optical sensor and control circuit. Since the weather maybe cloudy or rainy, there is a spare AC power supply loop consist of transformer, bridge rectifier, filter and voltage regulator to prevent battery undercharge or circuit maintain. When the output current of battery is less than the preset value, the power source of white LED lamp will be switched over to spare AC power supply loop by the comparative and switching circuit.

用太阳能板，在日间吸收太阳光，将能源用DC-DC充电器储存於蓄电池中，夜间时由光感测控制电将蓄电池放电，提供白光LED灯所需的电源，为预防阴雨天蓄电池充电足或电故障维修，将使得灯无法点，另有市电经变压器与整稳压后之预备供电回，於蓄电池输出电低於预设值时，将白光LED灯电源换至市电预备回。
