为确定云广±800kV线路对地及交叉跨越距离,首先根据国内外资料确定有影响的环境标准,包括静电场、合成场强、离子流密度、无线电干扰及可听噪声等,在公众能到达的地方,按美国电科院EPRI Report EL2257推荐的方法进行静电场、合成场强、离子流密度计算,根据计算结果确定其导线最小对地距离;再根据系统确定的操作过电压倍数及电气绝缘强度(空气间隙)来确定在人不宜到达地方的交叉跨越距离;部分区域综合考虑地面合成场强及电气绝缘强度的影响确定相关距离。根据以上结论提出了±800kV线路导线对地最小距离及交叉跨越间隙的建议值。

This paper focuses on advanced analysis techniques and design considerations of DC interference generated by HVDC electrodes during normal bipolar and temporary monopolar operations on neighboring metallic utilities, with a special emphasis on buried gas and oil pipelines. This study examines the level of pipeline corrosion, the safety status in the vicinity of exposed appurtenances and the impact of DC interference on the integrity of insulating flanges and impressed current cathodic protection (ICCP) systems. Computation results obtained for different soil models show that different soils can lead to completely different DC interference effects. The results and conclusions presented here can be used as a reference to analyze the severity of DC interference on pipelines due to proximate HVDC electrodes.

This paper focuses on linear-quadratic(LQ)optimal control for a class of systems governed by first-order hyperbolic partial differential equations(PDEs).Different from most of the previous works,an approach of discretization-then-continuousization is proposed in this paper to cope with the infinite-dimensional nature of PDE *** contributions of this paper consist of the following aspects:(1)The differential Riccati equations and the solvability condition of the LQ optimal control problems are obtained via the discretization-then-continuousization method.(2)A numerical calculation way of the differential Riccati equations and a practical design way of the optimal controller are ***,the relationship between the optimal costate and the optimal state is established by solving a set of forward and backward partial difference equations(FBPDEs).(3)The correctness of the method used in this paper is verified by a complementary continuous method and the comparative analysis with the existing operator results is *** is shown that the proposed results not only contain the classic results of the standard LQ control problem of systems governed by ordinary differential equations as a special case,but also support the existing operator results and give a more convenient form of computation.
