Embodiment Construction
[0020] The method for layered sharing of electric power telecontrol raw data and equipment control includes the following steps:
[0021] Step 1. According to the interaction process of telecontrol raw data, the system architecture is designed into a three-layer model from bottom to top: substation layer, telecontrol raw data layer and automation system layer, where each system in the three-layer model uses the same telecontrol Channel table; telecontrol raw data layer includes telecontrol raw data sharing system;
[0022] Step 2. The data channel transceiver module in the telecontrol raw data sharing system establishes connections with multiple substations in the substation layer through a unified telecontrol channel table; the telecontrol raw data sharing system combines the received raw data with the telecontrol raw The telecontrol channel corresponding to the data establishes a shared data model corresponding to the channel and data;
[0023] Step 3. Multiple systems in t...

The invention relates to a method for hierarchically sharing power telecontrol original data and realizing equipment control. The method comprises the following steps of: firstly, designing a system into a three-layer model: a substation layer, a telecontrol original data layer comprising a telecontrol original data sharing system, and an automatic system layer; then, connecting the telecontrol original data sharing system with multiple substations in the substation layer; connecting multiple systems in the automatic system layer to a data publishing and control module, subscribing required data, distributing the ID to each automatic system by the telecontrol original data sharing system, and establishing a data publishing relationship table; and finally, sharing power telecontrol original data or controlling equipment. In the method disclosed by the invention, the various layers realize corresponding functions, and provide interlayer services; the coupling degree among diversified communication of the substations and the automatic systems is reduced; limitation of a communication line among the automatic systems and the substations is broken through; furthermore, the requirement of a substation telecontrol machine on the client side number of the various automatic systems is shielded; and thus, telecontrol original data network sharing is realized.
Description
technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a method for layered sharing of electric telecontrol original data and equipment control. Background technique [0002] The existing electric power automation system mainly relies on two communication methods, network channel and serial channel, to obtain telecontrol raw data. The raw data transmission of the substation terminal remote machine generally only satisfies four channels. Even if the substation uses data forwarding to increase the number of channels, it will face the practical problems of accessing more clients and maintaining the remote control channels of each substation. On the one hand, it is constrained by the limitation of the number of clients imposed by the telematics; on the other hand, it is constrained by the current layout of data network communication line resources. [0003] For the scheme of direct forwarding of telecontrol r...
