The frequency of broken-line fault occurred in distribution network is increasing over the past years. Broken-line fault will create negative sequence and zero sequence voltages, which will seriously affect the normal work of loads. However, distribution network has not equipped with special protection against broken-line fault yet. In this paper, single-phase broken-line fault in distribution network is studied, features of the voltages at both ends of the fault line and the current flowing through the fault line are analyzed by using symmetrical component method combined with phasor diagrams when various single-phase broken-line fault occurs, and it proposes the main criterion and the additional criterions based on the theoretical analyses, as well as a method to judge the section that the broken-line fault located. Finally, simulation analysis is carried out through PSCAD/EMTDC, which ensures the correctness of the theoretical analysis and the protection criterions.

This paper proposes an innovative solution to electrification of micro loads in the surroundings of high voltage transmission lines routes. Rural electrification of these loads is not trivial due to technical and economical aspects. These loads can be supplied by using the energy loss that is confined near to isolated shielding wires. The alternative consists of isolating a section of a shielding wire and needs a resonant reactor for voltage regulation. The main characteristics of the proposed system are presented, together with steady state results obtained with PSCAD and ATP programs.

An important purpose of building VSC-HVDC is to eliminate the overload and optimize the power flow in electric power network. From the points of the transmission network, a VSC-HVDC in electric power network influences the two end nodes' injection power of DC transmission line virtually and the injection power will further influence the distribution of branch power. The elimination of overload in electric power network that caused by VSC-HVDC has been considered when making transmission network expansion planning. A fast optimization model for power of transmission network including VSC-HVDC is built to minimize the network power loss. A new genetic operation called shift operation which will change the order of chromosome's local coding is added to the algorithm to keep the diversity of population. Garver-6 system is taken as an example to verify the correctness of the fast optimization model and prove that the genetic algorithm with shift operation can avoid local convergence more effectively. The genetic algorithm with shift operation is a beneficial attempt to improve the global convergence of genetic algorithm. The fast optimization model for power of transmission network including VSC-HVDC is proved to be practical.

With the development of smart distribution network, the distribution system is introduced with a large number of distributed generations (DGs). It becomes an active network that both the load and fault currents flow two-way, which leads to serious impacts on the protection's selectivity and sensitivity. In this paper, by analyzing current characteristics of a typical distribution network with DGs, a new distributed decision protection method which combines traditional over-current scheme and distributed wide-area protection is proposed. In this method, each line needs to install a smart terminal unit (STU) which obtains local data of current amplitude and direction in real time and processes them into logical values used to realize a specified logical operation. According to local and adjacent STU's calculation results, STUs can judge the fault area without synchronous sampling and isolate the fault by controlling the local protective devices accurately and quickly.
随着智能配电网的发展,配电系统引入了大量分布式代(dg)。负载电流和故障电流双向流动成为一个有源网络,严重影响了保护的选择性和灵敏度。本文通过分析典型配电网络的电流特性,提出了一种将传统过流方案与分布式广域保护相结合的分布式决策保护方法。在这种方法中,每条线路需要安装一个智能终端单元(smart terminal unit, STU),实时获取本地的电流幅度和方向数据,并将其处理成逻辑值,用于实现指定的逻辑操作。根据本地和相邻STU的计算结果,无需同步采样即可判断出故障区域,通过控制本地保护装置准确、快速地隔离故障。

the aim of this work is to develop an application which has the capability of modeling and optimizing regular shape (rectangular, square or L shape) ground grids under a two-layer soil model. The ground grid optimal design is the focus of this paper by using a 3-step optimization method: 1) using IEEE-80 equations to calculate touch and step potentials, which makes constraints continuous and differentiable for gradient descent methods; 2) using the optimal solutions from step 1 as the initial input into a pattern search algorithm by applying a more accurate but non-differentiable touch and step potential calculation method; 3) performing a perturbation test to determine whether the results from step 2 are globally optimal, otherwise using a genetic algorithm to re-optimize the solution from step 2 until it passes the perturbation test.

Fractional frequency transmission system (FFTS) is a promising solution to offshore wind power integration. The back-to-back modular multilevel converter (MMC) and modular multilevel matrix converter (M3C) are universally regarded as two promising ac/ac converter candidates of the next generation. This paper performs a detailed comparison between back-to-back MMC and M3C with special emphasis on their total capacitor and semiconductor ratings. The arm current and capacitor ripples are first analyzed, then comparison results of a 220 kV, 500 MW case is given. In terms of peak-current-based and RMS-current-based total semiconductor ratings the M3C is 42.56 % and 22.97 % larger respectively, while its total capacitor rating is merely 33.15% of the back-to-back MMC. The better candidate can be determined according to the quantitative comparison results and the latest prices of semiconductors and capacitors.

Facing the challenges posed by the penetration of a new fleet of renewable energy resources which are variable and distributed in nature, transmission organizations and grid operators around the world are in the process of enhancing their dispatch systems with broader capabilities and higher economic efficiency. Traditionally, static line rating (SLR) of a line is conservatively calculated under the “worst-case” operating conditions and are updated infrequently. These conservative assumptions may restrict the line capacity whenever the real weather condition is less stressful. More accurate assessment of transmission flow limits will directly impact the efficiency of system operations. Weather-based real-time dynamic line rating (DLR) is the current limit determined by real-time measurements of weather conditions surrounding the conductor. Increasing thermal line ratings, DLR has the potential to reduce transmission congestion and enhance operational efficiency. This paper applies DLR to the co-optimization problem of real-time energy and reserves using a security constrained economic dispatch (SCED) algorithm. Using real-time DLR, we demonstrate that the real-time SCED is able to dispatch the system more economically, relieve transmission congestion and reserve scarcity, and as a whole improved operational efficiency without compromising system security. Case studies are performed on a large power system of 48,000 transmission lines.
