    High voltage direct current (HVDC) / High voltage alternating current (HVDC) transmission lines have been implemented in many countries, including Australia, Brazil, China and Sweden and the safety concerns as the result of the high electromagnetic-radiation underneath the HVDC/HVAC lines have garnered increased public attentions. With the large-scale implementations of HVDC/HVAC transmission lines, the environmental impacts due to electromagnetic waves have become a focus of public attention in the following technical parameters: electric field, ion current density, space charge density, radio interference, audible noise, etc. Here, we report on the model, design and testing of electric field sensors to measure the electric field at the ground level under the HV transmission lines for the smart grid. This study utilized different principles to establish electric field measurement system based on the wireless sensor networks. Afterwards, these sensors were successfully tested and utilized at the national high-voltage test base.

    Simulation methods are widely-used in the field of railway planning and operations. However, the various tools are all lacking with respect to the standards they utilise as well as their published interfaces. For an end-user, the basic mechanism and the assumptions built into a simulation tool are unknown, which means that the true potential of these software tools is limited. One of the most critical issues is the lack of the ability of users to define a sophisticated workflow, integrated in several rounds of simulation with adjustable parameters and settings. This book develops and describes a user-based, customisable platform. As the preconditions of the platform, the design aspects for modelling the components of a railway system and building the workflow of railway simulation are elaborated in detail. Based on the model and the workflow, an integrated simulation platform with open interfaces is developed. Users and researchers gain the ability to rapidly develop their own algorithms, supported by the tailored simulation process in a flexible manner. The productivity of using simulation tools for further evaluation and optimisation will be significantly improved through the user-adaptable open interfaces.
