Visual modeling method for capability description file of direct-current protection control device

Abstract

The invention discloses a visual modeling method for a capability description file of a direct-current protection control device. A plurality of logic equipment is arranged in the capability description file of the device, a plurality of logic nodes are arranged in each logic equipment, and each logic node is provided with a plurality of data members; and the visual modeling method for the capability description file of the direct-current protection control device comprises the following steps that: visual programs are divided into a plurality of applications according to functions, a plurality of pages are managed by each application, the logic equipment is mapped into an assembly of a plurality of applications, and an application name list which can be managed by the logic equipment is arranged by signs; the operation of visual modeling is carried out for events, remote signalling, remote measuring, remote control, remote regulating and fixed values; and the capability description file of the device is automatically formed. Complicated technical terms can be shielded for application personnel according to the method, the configuration of a model is intuitively carried out in a mode of figuring, the workload of the configuration is relieved, the method is also related with application programs automatically, the capability description file of the device is automatically formed, and the correctness of the configuration is ensured.

Description

technical field [0001] The invention belongs to the field of direct current protection control, and in particular relates to a visual modeling method for device capability description. Background technique [0002] In addition to the three functions of control, protection and monitoring, the DC control and protection system also includes the configuration and communication maintenance of the entire system. In the current DC control system, a dedicated or custom communication protocol is often used to communicate with the control system of the operator. This situation mainly has the following problems: 1) The information of the DC control and protection host needs to be connected to the remote dispatcher through telecontrol , the remote dispatching often adopts the standard IEC60870-5-103 or IEC60870-5-101 protocol. During the conversion process, manual information configuration and point-to-point operations are required, which is not conducive to project implementation; 2) I...

Problems solved by technology

In the current DC control system, a dedicated or custom communication protocol is often used to communicate with the control system of the operator. This situation mainly has the following problems: 1) The information of the DC control and protection host needs to be connected to the remote dispatcher through telecontrol , the remote dispatching often adopts the standard IEC60870-5-103 or IEC60870-5-101 protocol. During the conversion process, manual information configuration and point-to-point operations are required, which is not conducive to project implementation; 2) In the converter station, often There are also communication control and protection equipment, which may not be compatible with the special communication protocol. When these equipment are connected to the control system of the operator, the work of protocol conversion is required.

Manual writing requires developers to have a deep grasp of the XML format, but most application developers are only familiar with event description configuration, and format errors often occur during configuration, which consumes a lot of time and effort

However, specialized tools are limited by the XML format and the kama standard. The model file of a device needs to manually input thousands of variable names, which often results in a mismatch between the configured variable address information and the application program, which brings a lot of proofreading. workload
