Overhead lines are the main way of power transmission in HVDC system. The fault traveling wave propagates along the line after lightning stroke, which may cause accidents. Fault identification and protection design rely on traveling wave analysis and calculation. The time domain solution of transmission line telegraph equations is complicated. Analysis in the complex frequency domain can reduce the computational difficulty. Firstly, this paper decouples the DC transmission line through phase-mode transformation and establishes the model. Then, the post-lightning boundary conditions are introduced and the calculation network is established. On this basis, it solves the expression of traveling wave based on nodal analysis method. Finally, with the numerical inverse Laplace transform, calculation results in complex frequency domain are converted into time domain. The proposed method can reflect the transient process after lightning stroke, which has engineering value for protection design.

With the further increase in power demand for highly concentrated load centers and the gradual formation of a power system with a high proportion of new energy sources, China will face severe risk of voltage instability. In this paper, firstly, the load bus voltage equation of simple Thevenin equivalent system is derived, and then the P-V and V-Q curves are obtained respectively. Secondly, the mutual restriction relationship between active and reactive power of load is discussed when there is a real value solution to the voltage. Finally, the relationship between the voltage of critical points of the P-V curves and the reactive power of the load, and the relationship between the voltage of critical points of the V-Q curves and the active power of the load are deduced respectively. The relationship of one-to-one correspondence between critical points of P-V curves and critical points of V-Q curves is proved according to the mutual restriction between active power and reactive power of load and monotonicity of critical voltage and load power function.

With the increasing frequency of data circulation and sharing in power monitoring systems, traditional network-centric protection strategies are insufficient to resist the growing risk of data leakage. This article analyzes the security risks in existing typical data circulation and sharing scenarios based on the demand for data security sharing in power monitoring systems. A data security protection technology framework covering the source layer, interaction layer, and terminal layer has been proposed from the perspectives of basic protection capabilities and key protection technologies, as well as an evaluation method for the protection technology capabilities of data circulation and sharing. This provides a reference idea for effectively enhancing the data circulation and sharing protection capabilities of power monitoring systems. © 2023 IEEE.

Current transformer (CT) disconnection of bus is prone to maloperation of bus differential protection. The existing criteria for CT disconnection do not fully consider the distinction between heavy load high impedance fault and external metal fault transfer to internal high impedance fault. And not fully consider the influence of one-half wiring circulation and unbalanced impedance on CT disconnection zero sequence criterion. Based on the theoretical analysis of the characteristics of braking current variation and zero sequence current distribution in the event of internal fault, this paper puts forward a fast blocking criterion of CT disconnection based on braking current and zero sequence current, and carries out simulation verification. Both the theory and the simulation show that there is a drop of braking current in the event of internal fault. The distribution of zero sequence current in the event of CT disconnection is obviously different from that in the event of internal fault. The criterion proposed in this paper can effectively and reliably distinguish CT disconnection from internal fault. © 2020 IEEE.

Soft open point (SOP) is applied to the power service restoration of the distribution network because of the advantages of flexible control mode and optimizing the operation of the distribution network. Taking advantage of parallel collaborative between independent peer smart terminals unit (STU) in distribution network and information interaction ways of working, distributed power service restoration method of distribution network considering soft open point is put forward, which brings the superiority of SOP in the aspect of power service restoration into full play and avoids the problem of large information collection and calculation in the centralized power service restoration method. Firstly, the structure, control mode and power service restoration model of SOP are introduced, and then the distributed power service restoration method of distribution network with SOP is described, which mainly includes distributed network topology search and the expression and calculation of constraint conditions. Finally, a numerical simulation is carried out to verify the effectiveness of the proposed method. © 2020 IEEE.

Considering that different energy subsystems have different control characteristics in equipment operations, an optimal multi-time scale coordination method for electricity-heating integrated system scheduling is proposed. It merges three optimal scheduling models based on three-time scales of day-ahead, rolling, and real-time. The coordinated optimization of electricity and heating energies with the same dispatch instruction is fulfilled in day-ahead scheduling. And all feasible scheduling instruction cycles are traversed in the rolling stage to improve the stability of system economic operation. The calculation examples show that the proposed overall strategy for multi-time scale scheduling can achieve multi-energy complementarity, and the optimization results have less deviation from the actual load. © Published under licence by IOP Publishing Ltd.

Precise time synchronization is widely used in several domains such as Internet of Things (IoT), communication industry, power system and so on. Among all-time synchronization protocols, IEEE 1588v2 Protocol has received extensive attention, due to its submicrosecond accuracy and high-cost performance. However, it is not great enough in the convergence performance of synchronization in software-only system. Therefore, the aim of this paper is to speed up the convergence by control the jitter in software-only system. There are several methods proposed to reduce the jitter brought by soft timestamp and nonreal-time operating system. We compare and analyze various methods and choose clock servo system to experiment. The results of experiments verify that the clock servo system reduces the convergence time and improves the synchronization accuracy to some extent. © 2019, Springer Nature Singapore Pte Ltd.
