China's use of a high-tension power grid as opposed to more expensive underground cables, and its crushing dependence on coal – for 80 percent of its electrical power – left it especially vulnerable to the storms.

中国使用的是一种高压电网而不是较为昂贵的地下电缆以及其极度依赖煤炭-供其百分之八十的电力-使得它在暴风雨中特别容易受到攻击。

Thirdly, on the basis of the above research, the transfer capability homogeneousness concept is put forward. The relationship between power system existing operating mode and ATC is taken as the key, and the ATC optimal decision-making under power market is thoroughly studied.

再次，在上述研究的基础上，提出电网输电均匀性的新观点，以电力系统现存运行方式或调度与输电能力的紧密联系为主线，对市场环境下的ATC决策问题进行了深入研究。

Focusing on the conflict, the relationship between SED and network homogeneousness of power system is studied in this paper. The variation of the network homogeneousness under different dispatch models is analyzed. It is concluded that dispatch mode, transfer capability and its distribution should be considered combining with unification, coordination and compromise, to improve system's ability of withstanding some unexpected accidents.

对此矛盾，针对给定的负荷需求模式，研究SED与电网输电均匀性调度间的关系，分析不同调度方式下对输电能力使用的影响规律，得出输电能力及其分布应与调度方式统一、协调、折中地进行考虑，以提高系统抵御意外扰动的能力。

The proposed methods are testified in the large-scale electric network, and the results of real topology error identification indicate its feasibility and effectiveness.

采用实际电网对拓扑变化辨识、实用化等方法进行验证，结果表明了本文方法的可行性和有效性。

In the paper, the author did some research on the Graphical Model Platform of MGMS, the subsystem of MGMS. The GMP mainly has four functions as follows. The first aspect is the drawing function of micro-grid power system, including drawing power equipment, selecting power equipment and delete power equipment etc. The second aspect is the function of modifying parameters of power equipment. The third aspect is the function of topology automatic identification of the power system. The last aspect is advanced application function of GMP, including topology analysis and the real-time monitoring of the micro-grid power system which is in operation.

GMP主要要实现以下四个方面的功能：首先是设备绘图功能，包括鼠标绘制设备图元、鼠标选中设备图元、删除设备图元等基本的人机交互绘制微电网接线图功能；其次是修改已建设备的属性；再有是建立与建立的图形系统一致的电力系统网络模型，即对已绘图形的网络拓扑自动识别；最后是在此基础上的高级应用功能，包括电力系统网络拓扑的着色分析和运行数据的实时显示功能。

According to the disadvantage of great current made by 660V/1140V AC motor which works under the mine when the AC motor starts, it can make power system and motor impactive.

根据在煤矿井下工作的660V/1 140V交流电动机起动电流大，对电网及电机造成冲击的缺点，设计了一种新型的矿用隔爆型软起动器。

In this paper, an incidence matrix of nodes and lines matching the actual distribution networks is established, which is created automatically by computer.

本文建立了与实际配电网节线图相对应的节点与线段关联矩阵，给出了一种简单的计算机自动生成方法。

This method can meet the inconstant characteristic and perfect the distribution of the var flow of complicated power system.

这种方法的缺点在于补偿量不能随电网参数波动而改变，不能动态解决无功分布不合理、电压波动大的问题。

Firstly,the inductive reactance on the resonance point was estimated.

并利用Matlab仿真平台，建立了中性点经消弧线圈接地的电网模型。

Huntcapacitor compensation is simple and economic, but it can not follow the change of inductive loadin system, it can not achieve dynamic compensation of reactive power.

VC可以根据电网中无功功率的状况进行无功补偿，但是，在实际应用中SVC离不开具有时滞性的大容量储能元件，不能做到瞬时无功控制。
