About the various ways it may be possible to provide an open grid including the outright purchase of hksar government , or even simply a fair tariff system for independent power producers to access the grid , said liam salter , director of asia - pacific climate and energy programme , wwf 开放电力网络的可行方法，包括由特区政府买下电力网络，或设立一个公平的收费机制，让独立的电力生产商加入输电网络。
With the rapid development of power net , more and more monitored nodes should be control . accordingly more nodes " voltage is out of delimitation . therefor , traditional method using experience of the operator cannot fit for the requirement of power system 随着电力网络不断增大，其需要监控的节点越来越多，监控节点电压越限的情况也日益增多，传统的根据运行人员经验来调节的方法已不能满足要求。
This paper analyses model and control system of upfc and tcsc , and respectively completes interface with network , upfc using equivalent load decoupled algorithm and tcsc using compensation algorithm . by programming software , transient stability computation for power system containing facts devices can is realized . the correctness and effectiveness are proved using numerical example in the modified epri - 36 bus system 本文详细分析了facts元件中upfc 、 tcsc的模型和控制系统， upfc采用等效负荷解耦算法， tcsc采用补偿法分别实现了与电力网络的接口，通过编制相关程序，实现了混合系统中含upfc 、 tcsc的暂态稳定计算，并以修改过的epri - 36节点系统为例，验证了该算法的正确性和合理性。
Its very nature makes it an especially good leapfrogger : it works using radio , so there is no need to rely on physical infrastructure such as roads and phone wires ; base - stations can be powered using their own generators in places where there is no electrical grid ; and you do not have to be literate to use a phone , which is handy if your country ' s education system is in a mess 正是它的那些特性使它成为一个很好的“跨越者” ：它使用无线电工作，因此不需要依靠像道路和电话线一类的物理基础设施；在没有电力网络的地方基站能使用自己的发电机供电；而且你不需要受过很多教育才能使用一部电话，如果你的国家的教育系统很糟糕的话它就很有用（很方便） 。
Through ( multi - level ) bordered block partition of the power system topology matrix , a bbdf coefficient matrix which is suitable for above decomposition is formed . when the equation is solved with parallel iterative method , convergence acceleration is achieved through damping newton method 通过采用(多重)对角加边的方法进行电力网络拓扑分割,以形成适合以上分解法求解的对角加边形式的系数矩阵,并行求解后并对迭代过程进行阻尼牛顿法修正,以达到加速收敛的作用。
My article integrated the characteristic of the present relay protective settings calculation on the basis of comprehensive analysis with the present technology and management system , introducing the adaptive concept . its purpose is that the relay protective settings of all the components or lines in the network can uphold protective integrality following the change no matter however the network changes . after programming an integrated relay protective settings calculation and management system for power plant , the validity and practicability of adaptive relay protective settings theory is proved 本文结合目前继电保护定值整定的特点，在对现有技术进行广泛分析的基础上，在继电保护定值计算和管理中引入了自适应的概念，它的目的是无论电力网络如何的发生变化，网络里所有元件(线路)的继电保护定值等能通过计算和管理适应这种变化而保持系统内保护的完整性。
This paper tries to analyze the detailed paths information between sources and flows based on the basic electrical principles and laws , and the electrical dissecting method can provide theoretical support for solving problems related to the paths between sources and flows 本文从电力网络的基本电气原理和规律出发,从如何正确分析电力网络源流之间发生电气供求关系的详细路径信息入手,系统地研究了电力网络源流路径的电气剖分方法,为解决许多与网络源流路径有关的问题提供了基础。
Therefore , the power department and users are concerned aboui harmonic and reactive compensation . the power department usually manage compute and measure the electric net " s harmonic condition and connected or new - connected harmonic load . and need to measure the harmonic vol tage current in some electric net " point . then , by manual making an in - depth analysis and statistics on measured - data , it can reduce harmonic harm on public not to take some effective measures 电力部门通常在实际中，需要对电网的谐波状况、已接入和新接入系统的谐波源负荷进行管理、计算及测量，需要对电力网络各点的谐波电压、电流实际水平进行测试，然后对测试数据进行人工分析统计，并以此采取相应措施降低或减少谐波对电网的危害。
Based on the brief introduction of the complexity of power system , this paper introduces the application of system complexity theory in power system and the research status , including self - organized criticality , cascading failure model , structure vulnerability and the evolution of cascading failure in complex power systems , and then further proposes that research on complex theory may provide a new area for the exploration of security and reliability of inter - connected power grids 摘要在简述电力系统复杂性的基础上，介绍了系统复杂性理论在电力系统中的应用以及研究概况，包括电力系统的自组织临界性、电力系统连锁故障模型和复杂电力网络的结构脆弱性和连锁故障演化等，进一步指出电力系统复杂性理论的研究可能为探索互联电力网络的安全性和可靠性提供一个新的方向。
However , by the time a lightning strike has traveled through the distribution network , surge arrestors will have dissipated a proportion of the charge , network impedance will have shaped the impulse and the residual energy can be represented in terms of its waveshape , and its peak current which is what will be present at a service entrance 然而，雷击经过电力网络进行传送以后，避雷放电器会将一部分能量泄放掉，网络的阻抗也会对电涌进行修整，而残余的能量将可以以它的波形来体现，其峰值电流也就是建筑物进入端将会出现的情况。
