Problems solved by technology

However, as the voltage level rises, the protection logic becomes more and more complex, and the development of new functional modules has seriously affected the progress of device development, which has nothing to do with labor cost control.
At the same time, a single functional module cannot cope with the complex trend of power grid wiring and the changing development of operation modes

Abstract

The invention discloses a method for developing an optimal protection measuring control device, and belongs to the technical field of electric automation. The method specifically comprises the steps of (1) creating a hardware environment; (2) processing protection variation by a Boolean manner; (3) decomposing protection logic; (4) traversing to find out a starting point of configuration; (5) traversing to find out an output element; (6) traversing to find out a feedback return ring; (7) creating a scheduling relationship and a connection line relationship based on the steps (4), (5) and (6) to operate the device. With the adoption of the method, the production device has the advantages of being fast to develop, high in efficiency, short in cycle, high in readability, and convenient to debug.

Description

Technical field [0001] The invention relates to a method for optimizing the development of a protection measurement and control device, and belongs to the technical field of electric power automation. Background technique [0002] With the continuous improvement of voltage levels, the smart grid has evolved into a high-order nonlinear and highly complex topology network. The stability of each device in the network has received great attention. Can the fault be located in time when the fault occurs, and the fault can be removed and the power supply restored with the least impact on the power grid. It has always been a research topic of smart grid technology. As an important device to ensure the self-healing of smart grids, protection measurement and control devices are widely used in power grids. In the EMS system of the master station, many units such as DTS simulation, static safety analysis, power grid failure analysis, etc. need to consider the influence of the protection m...
