The principle of the novel single-phase hybrid active power filter is described in detail. Based on the above analysis, Kalman filtering approach for estimation of harmonics is presented to improve the speed and precision of harmonic detection, and it also can avoid the influence made by voltage distortion on harmonic detection. A new current control strategy based on energy balance is presented to regulate the active part absorbing or releasing active power and control the inverter to produce current opposite to the harmonic current reflowing in injection branch, the above method combined with harmonic current tracking control that keeps the stabilization of dc-side voltage and improve the reliability of the system.

At first the current sampling values pass through virtual digital CVTs. And then the voltage and current sampling values are processed by a low pass filter. According to the instantaneous value of transmission line voltage, the current instantaneous values of shunt reactors and P equivalent circuit capacitance can be calculated. After removing these two kinds of current, sampling value differential protection based on all components and fault component can be applied.

Just as I had set my Mast and Sail, and the Boat began to stretch away, I saw even by the Clearness of the Water, some Alteration of the Current was near; for where the Current was so strong, the Water was foul; but perceiving the Water clear, I found the Current abate, and presently I found to the East, at about half a Mile, a Breach of the Sea upon some Rocks; these Rocks I found caus'd the Current to part again, and as the main Stress of it ran away more Southerly, leaving the Rocks to the North-East; so the other return'd by the Repulse of the Rocks, and made a strong Eddy, which run back again to the North-West, with a very sharp Stream.

我刚竖起桅杆张好帜，船就开始向前行驶了。我发现四周水色较清，知道那股急流在附近改变了方向。因为，水急水则浊，水缓水则清，我知道那股急流在这儿已成了强弩之末了。不久我果然发现，在半海里以外，海水打在一些礁石上，浪花四溅。那些礁石把这股急流分成两股，主要的一股继续流向南方，另一股被礁石挡回，形成一股强烈的回流，向西北流回来，水流湍急。

To solve the above problems, a novel resonance injection type hybrid active power filter is presented, it allows the energy exchange between the DC-side capacitor and grid, DC-side voltage will be stabilized after the proposed control method base on the regulation of reactive current is adapted. On the other hand, a new current control method is proposed which is based on the control of error between injection current and harmonic current compensated by passive power filter using recursive PI.

在此基础上结合提出的基于基波无功电流闭环调节的直流侧电压控制方法，保证了直流侧电压的稳定；提出了采用递推积分将无源滤波器作用后电网谐波电流与注入支路补偿电流进行闭环比较控制以获得参考电流的方法，减小了误差，提高了系统的控制精度。

In this paper, we mainly study the alternating group A_4 actions on spin 4-manifolds. First we discuss the special action of A_4 on K3 surfaces of Fermat type, we compute the fixed points set of this action and some invariants of the group action, also we get some topological properties. Then we study the A_4 actions on general K3 surfaces and obtain some similar results.
