Space charge density around the conductor surface is a boundary condition in the ionized field computation of HVDC transmission lines. Upstream finite element method is a common method to study ionized field problem. In this method, the distribution regularity of space charges around the conductor surface needs to be determined before computation. The difference of distribution assumptions will cause different results. In this paper, three distribution assumptions of space charges around conductor surface in ionized field computation are summed up. The effect of these assumptions is evaluated by a reduced-scale experiment in the laboratory. Finally, computation results of -800kV unipolar and ±800kV bipolar equivalent single transmission lines are discussed, and the percentage of relative error is given.
导体表面空间电荷密度是高压直流输电线路电离场计算中的一个边界条件。上游有限元法是研究电离场问题的常用方法。在这种方法中,需要在计算前确定导体表面周围空间电荷的分布规律。分布假设的不同会导致不同的结果。本文总结了电离场计算中导体表面空间电荷的三种分布假设。这些假设的影响是通过实验室缩小规模的实验来评估的。最后讨论了-800kV单极和±800kV双极等效单线的计算结果,并给出了相对误差百分比。

There are various incentive policies promoting the integration of renewable energy in power system planning. This paper proposes an entropy based matter-element model for incentive policy evaluation. A comprehensive evaluation system is established, which includes evaluation indexes concerning the cost, reliability, environmental effects and operational flexibility of the planning result. On this basis, entropy method is applied to objectively assess the weight of the evaluation indexes in varying criteria. Moreover, with coordinate transformation introduced into the matter-element model, the incentive policies are distinguished by more balanced and dispersed grades. Case study based on a real-world power system shows that the proposed matter-element model better distinguishes different incentive policies than the conventional model, with more reasonable, flexible and objective conclusion. This model can also be used to further analyze the role that future power system plays in energy revolution.

Renewable energy sources (RES) and HVDC links are typically interfaced with the grid by power converters, whose performance during grid faults is significantly different from that of traditional synchronous generators. This paper investigates the performance of grid-connected voltage source converters (VSCs) under unbalanced faults. Conventional positive-sequence synchronous reference frame (SRF) control is presented first, followed by three different negative-sequence current control strategies considering reactive power injection and converter current limit. The simulation results indicate that the performance of VSCs varies with their control strategies. Negative-sequence current control is necessary to restrict converter current in each phase under unbalanced faults. Among presented control strategies, the balanced current control strategy complies with the present voltage support requirement best and further requirements should be specified if a set of controlled unbalanced current is expected under unbalanced faults.
可再生能源(RES)和高压直流输电链路通常通过电源变流器与电网连接,其在电网故障时的性能与传统的同步发电机有很大不同。研究了不平衡故障下并网电压源变换器的性能。首先介绍了传统的正序同步参考帧控制,然后提出了考虑无功功率注入和变流器限流的三种不同的负序电流控制策略。仿真结果表明,vsc的性能随控制策略的不同而变化。负序电流控制是在不平衡故障情况下限制变换器各相电流的必要手段。在所提出的控制策略中,平衡电流控制策略最符合目前的电压支持要求,如果在不平衡故障下期望得到一组受控的不平衡电流,则需要进一步规定要求。

In this paper, basic principles, advantages and disadvantages, development and applications of different types of fault current limiter (FCL) are described. Effects on safety and stability of power grid and optimization configuration are also expounded with the application of FCL in aspects of relay protection, reclosure, transient power angle and voltage stability. In addition, several key problems of FCL engineering application are summarized. The development trends of FCL research and application are also proposed. It points out that FCL will play a unique role in fields such as improving the transmission capacity of DC Receiving-side, reducing the risk of commutation failure, improving power quality, enhancing large-scale new energy integration capability and so on. Due to the limitation of technical and economic constraints, economical FCL based on the normal electric equipment is still the first choice for application at present. However, with the increasing maturity of large-capacity and high-voltage self-turn-off power electronic devices, solid-state current limiter based on power electronic technology will become the research and application hotspot in the future.

Distribution companies (DSCOs) are trying to reduce the high real loss and manage the poor voltage profile, so power loss minimization and voltage profile improvement are the main and important tasks to be faced by electrical engineers in the distribution system (DS). To achieve this goal, distribution system reconfiguration (DSR) is one of the greatest keys and vital analysis to reduce power loss and enhance system voltage profile. In this paper, Modified particle swarm optimization (MPSO) is used for solving the DSR with the objective of minimizing real power loss in the presence of a regular of some constraints. To prove the applicability of the proposed method, MPSO has been applied on operated example the standard IEEE 33-bus system and the results compared with the other popular algorithms. It observed from the numerical results of the test that the real power loss is reduced by 31%, the average system voltage enhanced by 2% and 2.5% improves the minimum voltage.

In line with the inevitable requirements of social and economic development, smart distribution network (SDN) has become a major trend of the world's power grid development currently. In this paper, in-depth analysis and evaluation on benefits of user's demand response is conducted under the smart distribution network. Taking full account of the diversity of SDN participating subjects and the difference of their core interests in the market environment, we establish the relevant evaluation index system. In order to reflect the real benefits of each index more realistically and effectively, each index of different subject comprehensively covers the definite and interval data. Grey Relational Analysis-Technique for Order Preference by Similarity to Ideal Solution (GRA-TOPSIS) is used to evaluate the demand response performance of intelligent distribution network. In the evaluation process, we innovatively introduce the Expert Scoring-Interval Centric Distance (ESICD) into subjective and objective comprehensive weight method, and do objective and comprehensive empowerment for each index. At the same time, the resolution coefficient is adjusted dynamically, which will make the results more scientific and objective. Finally, under different matching mechanisms, a numerical example, evaluated synthetically on the benefit of the demand side resources with wind and light as the main body, is given to verify the feasibility of the evaluation method. Simultaneously, matching combinations with optimal demand side resources are selected, thereby, providing a strong reference to development ideas for the future development of demand-side.

The rated transmission voltage of HVDC transmission project has reached 800kV, when transfer capacity to 10000MW, rated current will be upgraded from 5000A to 6250A. This will cause the local temperature of fittings being very high; therefore studying the reliability of existing fitting after capacity enhanced is very necessary. In this paper, a two-way suspension fitting is taken for the research object, thermal-electric coupled field is used for the finite element method (FEM). In the case of the rated current is 5000A, when the contact resistance takes different values and change the material properties of the strands of the fitting, obtain the temperature distribution. It also test this existing fitting with the reliability after capacity enhanced. The above researches are of certain significance to reduce the local temperature rise of the valve hall fittings and provide the basis for the design of HV valve hall fittings.
高压直流输电工程的额定输电电压已达到800kV,当输电容量达到10000MW时,额定电流将由5000A提升到6250A。这将导致配件的局部温度非常高;因此,研究现有拟合在扩容后的可靠性是十分必要的。本文采用双向悬架拟合作为研究对象,采用热电耦合场进行有限元分析。在额定电流为5000A的情况下,当接触电阻取不同值并改变接头各股的材料特性时,得到温度分布。并对现有管件进行了容量增强后的可靠性测试。以上研究对降低阀厅管件局部温升具有一定的意义,为高压阀厅管件的设计提供依据。

The above researches are of certain significance to reduce the local temperature rise of the valve hall fittings and provide the basis for the design of HV valve hall fittings.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131261708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stability issues will arise with multiple HVDC links feeding an AC power network, among which voltage stability is of great significance. In this paper, the quantitative relationship is obtained between static voltage stability and the associated factors by using the multivariate regression analysis. The information aggregation approach is employed to derive independent variables for constructing a multivariate regression model. Simulation results on a five-infeed HVDC system verify the effectiveness of the method.
当多个高压直流线路接入交流电网时,会产生稳定性问题,其中电压稳定性具有重要意义。本文采用多元回归分析方法,得到了静态电压稳定性与相关因素之间的定量关系。采用信息聚合的方法导出自变量,构建多元回归模型。仿真结果验证了该方法的有效性。
