Embodiment Construction

[0034] like figure 1As shown, a method for automatically generating a transmission network topology map applied to cloud SCADA provided by the present invention comprises steps:

[0035] S1: Take the substation or power station in the transmission network as the point in the topology of the transmission network, use the transmission line as the connection in the topology of the transmission network, and randomly generate the initial topology map of the transmission network; where the connection is a straight line segment ; The two ends of the connecting line are respectively connected to two points; in this embodiment, the initial topology of the transmission network can be directly randomly generated by existing methods or software (for example: automatic arrangement plug-in method), or manually drawn in the software Region drawing generation is a prior art, and it is not the content to be protected by this application, so it will not be described in detail here.

Abstract

The invention provides a method for automatically generating a power transmission network topology graph applied to a cloud SCADA. The method comprises the steps of (S1) randomly generating an initialtopology graph of a power transmission network, (S2) calculating a modified coordinate of each point in the initial topology graph of the power transmission network, (S3) counting and obtaining the number cross_tt of intersection points existing in an initially modified power transmission network topology diagram, (S4) initializing an endpoint distance threshold d_max and taking the initially modified power transmission network topology diagram as a topology diagram of the current power transmission network, and (S5) to (S8) updating the topology diagram of the power transmission network by aforce guiding algorithm and reducing the intersection points. According to the method, the intersection points of the topology diagram are greatly reduced, therefore, the topology diagram of the power transmission network is clearer, the analysis and design work of the staff of a power grid are facilitated, and the strong protection is provided for the monitoring control, scheduling, analysis, planning and the like of a power system.

Description

technical field [0001] The invention relates to the technical field of power system distribution network automation, in particular to a method for automatically generating transmission network topology diagrams applied to cloud SCADA. Background technique [0002] SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) system is a computer-based production process control and scheduling automation system. It can monitor and control the operating equipment on site to realize various functions such as data collection, equipment control, measurement, parameter adjustment and various signal alarms. With the continuous expansion of the scale of the plant, the sharp increase in the amount of data collected, and the rapid development of computer technology, in order to meet the requirements for easy scalability, scalability, and high reliability, it is urgent to break the original storage "IOE" architecture and important The "active-standby...
