Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
As shown in fig. 1-5, the new energy remote centralized control center communication channel system constructed based on the private power network according to the present invention is divided into a centralized control center access system architecture module, a centralized control center-to-power network scheduling channel module, a terminal substation-to-centralized control center channel module, and a service data transfer system module according to different functions of the communication channel. If the remote centralized control center is compared with the brain of the whole system, the terminal sites are limbs and the trunk, and the communication channel is an artery and a capillary vessel which are communicated with the whole body. The centralized control center collects and controls the terminal substations uniformly, and the centralized control center platform realizes the monitoring of the terminal stations uniformly. The system is divided into a three-level framework of a group monitoring analysis layer, a centralized control center layer and a new energy substation layer. According to the node position and system positioning of the remote centralized control center in the whole power grid structure, the method can be roughly divided into three main channel requirements: a channel from the remote centralized control center to the provincial dispatching center; a channel from the remote centralized control center to the terminal station; and a remote centralized control center to a group unified management system channel.
Referring to fig. 2, the end station configures a dedicated data acquisition gateway machine, a network communication device, a network boundary secondary safety protection device, and a comprehensive protection device, accesses each service subsystem partition into a front-end acquisition system, and sends the system to a centralized control center through a specific channel, so as to implement unified monitoring and control by the centralized control center. The system is used for comprehensively collecting main information of all devices on site at the substation end, and fully utilizing efficient data transmission modes such as 'instant transmission, periodic transmission, calling transmission' and the like to realize data acquisition and transmission.
According to the difference of service types and the difference of requirements on channel reliability and instantaneity, data channels can be divided into two types: the first kind of data has high real-time, reliability and continuity requirements, and important production and dispatching data of the power station can pass through a special channel, and the second kind of conventional services such as video monitoring, administrative telephone and the like can pass through a service channel of a leased public network operator. The first type of data channel has high performance parameters and safety protection requirements, and meanwhile, due to geographical position reasons, it is difficult for power generation enterprises to build a special channel of the terminal station-centralized control center, and meanwhile, the national power grid has built complete optical cables and transmission channels covering various voltage levels, and the channel resources are fully utilized to build the data channel of the terminal station-power grid-centralized control center, so as to build a reliable and stable centralized control system.
Referring to fig. 3, the centralized control center access system architecture module is mainly used for establishing a dedicated channel between a centralized control center or a data center of each non-grid energy user and each operation and maintenance station and plant station which are relatively dispersed through the existing optical cable and transmission network channel, and accessing the centralized control center to a communication channel system; most of centralized control centers or data centers of all non-grid energy users are located in cities, all operation and maintenance stations and plant stations are scattered in relatively scattered suburbs, mountainous areas and the like, and a data channel between the operation and maintenance stations and the plant stations is a weak link; the national power grid is provided with a complete optical cable channel and a transmission net rack, all stations of 35kV and above are basically covered, and optical cables to nearby transformer substations are basically built in a terminal energy station along with a primary line; a special channel is established by utilizing the existing optical cable and the transmission network channel, so that the terminal substation is realized to establish a communication channel system to the centralized control center by utilizing the special power.
Referring to fig. 4, the module from the centralized control center to the power grid dispatching channel mainly includes a dispatching channel from the centralized control center to the power grid in combination with a specific position and a peripheral power grid architecture, so as to realize dispatching connection between the centralized control center and the power grid; the module mainly comprises an optical cable channel and a data channel, wherein the construction of the optical cable channel needs to be combined with the geographical position of a centralized control center, and two optical cable channels with completely different paths from the centralized control center to a nearby transformer substation or a dispatching station are constructed; the data channel is constructed by mainly utilizing the constructed optical cable channel to enable MSTP equipment or router equipment with an optical port configured in the centralized control center to directly reach or jump to a power grid station and open an optical path or a data channel to the power communication transmission network. In order to meet the diversity of the access service of the centralized control center and the flexibility of service configuration, MSTP is selected for realization.
The terminal substation-centralized control center channel module is mainly used for accessing a county-level access network, a prefecture convergence network and a provincial-level core network by utilizing original channel resources of the terminal substation, and finally realizing channel organization from the terminal substation to the centralized control center, wherein the terminal substation-centralized control center channel module comprises light path channel construction and service channel construction; when the terminal station is built, a related optical cable channel and a data channel to a nearby transformer substation are built in a matched manner, and a necessary 2M or hundred-million data channel is provided for power station access by using original channel resources.
Referring to fig. 5, the service data flow system module mainly uses a constructed transmission network architecture to transmit 2M or hundred megabyte data step by step, and finally realizes that the end service data is converged to the centralized control center by the end substation; the newly added service system of the terminal station in the service data circulation system module is accessed to the transmission equipment configured by the terminal station in the form of E1 interface or FE interface, then is accessed to the regional transmission network through the optical channel link to the local transmission network, and then the service enters the provincial transmission network through the interconnection and intercommunication of the provincial network transmission network and the local transmission network, and the landing of the service is realized by using the transmission network equipment configured in the centralized control center; as the new energy substation generally has small installed capacity and low network voltage, most of the originally accessed transmission networks are county-level transmission networks, and if some substations are accessed to provincial transmission networks, the service circulation can be realized directly through the provincial transmission networks. Because the data formats of the E1 interface service and the FE interface service in MSTP are different, there is a slight difference in terminal configuration.
The system architecture of the invention is as follows: the new energy centralized control center is positioned in the core of the urban area or region, an optical cable channel is built, a proper access station is selected to access the electric power optical cable network, and transmission equipment is built to access the electric power communication provincial core transmission network by relying on the built optical cable channel; the terminal substation accesses a county-level electric power access transmission network by using an original optical cable network accessed to a power grid and a configured and opened optical path, and constructs a transmission network channel and a data service channel from the terminal substation to a centralized control center by using the county-level access transmission network, the city-level convergence transmission network and the provincial-level core transmission network.
