“…The electrical environment under an HVDC transmission line is characterized by several different electrical parameters. These parameters are the electric field, the ion current density, the space charge density, the radio interference, the audible noise, and the magnetic field [2, 3]. The electric field under transmission lines is one of the important parameters for evaluation of electromagnetic environment concerned by people.…”

A wireless sensor network-based distributed measurement system is designed for collecting and monitoring the electric field under the high voltage direct current (HVDC) transmission lines. The proposed system architecture is composed of a group of wireless nodes connected with electric field sensors and a base station. The electric field sensor based on Gauss's law is elaborated and developed. For the design of wireless node, the ARM microprocessor and Zigbee radio frequency module are employed. The proposed system has been used in China's state grid HVDC test base and the in situ power transmission projects. Based on the experimental results, the proposed measurement system demonstrates that it can adapt to the complex electromagnetic environment under the transmission lines and can accomplish the accurate, flexible, and stable demands of the electric field measurement.

“…Theoretical and experimental research has been executed for numerous a long time in order to understand and control the corona effect. Indeed, many of these studies were aimed at reducing its harmful effects which manifest themselves on high voltage electric power transmission lines [1][2][3][4]. Currently, the corona discharge is at the basis of several industrial applications, such as electrostatic dust precipitation [5], surface treatment [6][7], ozone generation [8][9], painting and spraying powders [10], granular mixtures separation [11][12], etc.…”

“…High Voltage Direct Current (HVDC) transmission systems are more favorable than the conventional High Voltage Alternating Current (HVAC) systems because of their economical, technical, and environmental advantages for long distance and bulk power transmission. To date, a ±800 kV HVDC transmission system has been in commercial operation and a ±1000 kV transmission system is being studied on a research basis in China [ 1 ]. The electrical environment under HVDC transmission lines is characterized by several different electrical parameters.…”

In the wireless sensor networks (WSNs) for electric field measurement system under the High-Voltage Direct Current (HVDC) transmission lines, it is necessary to obtain the electric field distribution with multiple sensors. The location information of each sensor is essential to the correct analysis of measurement results. Compared with the existing approach which gathers the location information by manually labelling sensors during deployment, the automatic localization can reduce the workload and improve the measurement efficiency. A novel and practical range-free localization algorithm for the localization of one-dimensional linear topology wireless networks in the electric field measurement system is presented. The algorithm utilizes unknown nodes' neighbor lists based on the Received Signal Strength Indicator (RSSI) values to determine the relative locations of nodes. The algorithm is able to handle the exceptional situation of the output permutation which can effectively improve the accuracy of localization. The performance of this algorithm under real circumstances has been evaluated through several experiments with different numbers of nodes and different node deployments in the China State Grid HVDC test base. Results show that the proposed algorithm achieves an accuracy of over 96% under different conditions.
