When microgrid is operated in islanded mode, VSGs can be divided into non-frequency regulation units and frequency regulation units, the former can generate power and participates in primary frequency control according to dispatching to mitigate system frequency deviation due to disturbances; the latter can offer referential voltage of microgrid and use secondary frequency regulation to implement no-error frequency control.

微电网孤岛运行时，将虚拟同步发电机分为非调频发电单元和调频发电单元，前者既能按照功率调度指令发电，又能参与一次调频，缓解扰动情况下系统频率的波动，后者提供微电网参考电压，并利用二次调频实现频率的无差控制。

Through theoretic reckoning and simulating analyzing, several control strategies for shunt APF were compared and chose ip-iq arithmetic ofthe instantaneous reactive power theory control strategy as the right scheme to produce the instructing current. Based on it, some new control arithmetic was subjoined to suppress the resonance in system and balance the dc side capacitor voltage. Two topologies of main circuit were compared and chose the three-phase voltage-source converter with a split-capacitor as its main circuit structure. The numerical scales of the dc side capacitor and inductance of reactors were calculated. The high-pass filters were designed to eliminate effectively the highfrequency harmonics produced by APF.

通过理论计算和仿真分析，比较了并联型APF的几种控制策略的优点和缺点，从中选择瞬时无功理论控制策略i_p-i_q计算方式为指令电流产生的算法，并在此基础上增加了抑制系统谐振和平衡直流侧电容电压的控制；比较了并联型APF主电路的两种常见形式，从中选择了三相电压型变流器的主电路形式；算出适合该APF的直流侧电容和出线电感的参数；设计出能有效消除APF产生的高次谐波的高通滤波器。

In this way users can acquire various kinds of local information in time. Users can also visit local equipment status informations or control it to carry out defence actions by the order set beforehand in short message. Thus a kind of bidirectional security and defense system syncretizing initiativeness and passiveness has been realized.

这样用户便可以及时地了解现场的各种信息，用户也可以通过手机短信息的方式，以预先设定好的指令来访问现场各种设备的状态信息或者控制现场设备执行防范动作，从而实现了—种双向的主动和被动相结合的安全防范系统。

Developing a system is simply a matter of transcribing what I already know, into the appropriate programming instructions

我知道答案，开发系统简单的仅仅是将我所知道的东西翻译为适当的程序指令。

As a wheelchair, the controller enables the user to drive and then provide an instruction to morph back into bed formation.

当它是轮椅的时候，控制系统可以让用户来驾驶并提供了如何转变到床模式的指令。

Secondly, using the model of the EMI, the optimizing the performance of the EMI of the Garfield is researched. Aim at the ARM7TDMI of the Garfield without the CACHE, using the burst transfer of the SDRAM, some caches are added in the Emirs the data or instruction can be perfected to the caches.

然后在外部存储控制器模型的基础上，对其架构进行优化，针对GARFIELD系列芯片使用的ARM7TDMI内核没有缓存的特点，利用SDRAM的突发传输特性，在外部存储控制器中加入CACHE，将数据或指令预取到CACHE中，减少对SDRAM访问的等待时间，从而提高系统性能。
