The invention discloses a method and system for determining the electric field intensity of line on-line monitoring equipment. The method comprises the steps: building a shared iron tower three-dimensional model according to the parameter information of a power transmission iron tower and a communication equipment antenna; based on the shared iron tower three-dimensional model, taking a power transmission iron tower and a power transmission wire as metal scatterers, loading a power supply according to the transmitting power of a communication equipment antenna, and determining a shared iron tower electromagnetic interference mathematical model; determining an electric field integral equation at the on-line line monitoring equipment according to the shared iron tower electromagnetic interference mathematical model; and calculating an induced current generated on the surface of the shared iron tower, solving the electric field integral equation by utilizing the induced current, and determining the electric field intensity of the line on-line monitoring equipment. The method for determining the electric field intensity at the line on-line monitoring equipment can provide data supportfor the radio frequency electromagnetic field radiation immunity requirement of the line on-line monitoring equipment sharing the iron tower.
Description
technical field [0001] The invention relates to the technical field of electromagnetic compatibility of high-voltage power transmission and substation engineering, and more specifically, to a method and system for determining electric field strength at a line online monitoring device. Background technique [0002] The power and communication sharing tower refers to the installation of communication equipment on the power tower, and the attachment of communication facilities such as cables, antennas and RRUs to the power tower itself, so as to realize the sharing of power and communication infrastructure resources. Sharing iron towers is a new mode of social resource sharing. First, using power iron towers to carry communication facilities can effectively reduce the land resources occupied by new communication iron tower base stations, protect the environment, beautify the landscape, and help build a beautiful China; Used in communication construction, it can promote fast and...
