A system for protection, control, metering, and monitoring of the delivery of electrical power is disclosed. Embodiments of the system provide input / output devices called bricks to receive analog and binary field data from primary equipment located in a power substation switchyard. The bricks are linked via fiber-optic patch cables and patch panels with one or more intelligent electronic devices (“IEDs”). In operation, the bricks convert the received binary and / or analog field data into digital signals, and transmit the digital signals synchronously to their associated IEDs using clock signals provided by each IED to the individual bricks. The bricks may accept a computer software code download from each of its master IED(s). Multiple code implementations, each tailored to the requirements of its master IED(s) can therefore co-exist on a single brick.

The invention discloses a three-dimensional transformer station semi-automatic reconstruction method based on laser point cloud data. The method comprises the steps: according to the existing standard of an electrical apparatus in the electric power industry, by collecting point cloud data and texture data of a transformer station, constructing a high-reality three-dimensional standard mode library of the electrical apparatus of the transformer station; by combining with the existing standard model of the transformer station, based on the laser point cloud data, performing ground feature extraction and identification, and automatically acquiring a position and a gesture of the electric apparatus in space; putting the three-dimensional electric apparatus into a corresponding point cloud three-dimensional scene, thereby completing vectorization of the point cloud data and further completing three-dimensional reconstruction of a transformer station scene. According to the three-dimensional transformer station semi-automatic reconstruction method based on the laser point cloud data, semi-automation of the three-dimensional reconstruction of the transformer station is achieved, and manual interference can be reduced, so that the production efficiency is improved, and the production cycle is shortened; by utilizing the precision advantage of laser point cloud, the precision of model products can be improved, and the whole simulation degree is high.

Systems, methods, and apparatus embodiments for electric power grid and network registration and management of physical and financial settlement for participation of active grid elements in supply and / or curtailment of power. Settlement is provided for grid elements that participate in the electric power grid following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. A multiplicity of active grid elements function in the grid for supply capacity, supply and / or load curtailment as supply or capacity, and are compensated through settlement for their functional participation in the electric power grid. Also, messaging related to settlement is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and / or grid operators.
