Problems solved by technology

[0004] The first and most serious problem is that the existing domain name management function is highly coupled with other power dispatching services and is not an independent application process. Unstable operation will affect the production safety of the power system
[0005] Second, the existing domain name management only supports one type of cross-scheduling organization data transmission, poor scalability, and domain registration, domain routing and other functions are not perfect enough to meet the requirements of multi-type cross-regional data transmission in a distributed environment
[0006] Third, the network programming model is simple, with small concurrency and low response efficiency, and cannot support large-scale distributed agents to perform cross-region positioning requests

Embodiment 1

[0042] figure 1 It is a flow chart of the domain name management method of the present invention, such as figure 1 A power domain name management method based on a dispatching data network is shown, comprising the following steps:

[0043] In the step of step 1 domain report, dynamic proxy service (distributed proxy) in the local scheduling organization reports online dynamics to the domain name reporting module in real time, and the domain name reporting module collects and monitors the state and the operating load information of the dynamic proxy service in real time;

[0044] Step 2: In the step of domain registration, the actively registered dispatching agency initiates domain registration to the visited dispatching agency, and the domain registration module of the actively registered dispatching agency sends a domain name registration connection request to the receiving registration module of the registered dispatching agency;

[0045] The receiving registration module o...

Embodiment 2

[0049] figure 2 It is a schematic diagram of the module of the domain name management method of the present invention, and the transmission of information is as follows: figure 2 As shown, the domain reporting module is provided with a monitoring thread and a domain reporting processing thread, and the monitoring thread is responsible for monitoring the registration request of the local dynamic proxy service (distributed proxy), and wakes up the domain reporting processing thread processing request; the distributed proxy (dynamic proxy service) Provide dynamic proxy services for regulatory agencies in different regions, and the underlying data exchange data through distributed agents.

[0050]The domain report processing thread is responsible for receiving the registration information of the local dynamic proxy service and saving the information in the local buffer.

[0051] The domain registration module includes a domain registration thread and a receiving response thread...

Abstract

The invention relates to a power domain name management method based on a dispatching data network. The power domain name management method comprises: a domain reporting step: a dynamic agent service in a local dispatching mechanism reports an online dynamic state in real time to a domain name reporting module; a domain registration step: a domain registration module of an active registering dispatching mechanism sends a domain name registration connection request, and a registered dispatching mechanism sends back response information; a domain synchronization step: the registered dispatching mechanism pushes information of a gateway application process state of the local dispatching mechanism in real time to the active registering dispatching mechanism; a domain positioning step: and a gateway applies the active registering dispatching mechanism to send a domain positioning request to the local so as to request information of a gateway application state of the registered dispatching mechanism. According to the method disclosed by the invention, an independent and stable domain name management process is formed, information interaction efficiency of different domains and different levels of dispatching mechanisms is improved, and security of operation of a power system is improved.

Description

technical field [0001] The invention relates to the field of electric power system communication, in particular to an electric power domain name management method based on a dispatching data network. Background technique [0002] Currently, in the smart grid dispatching control system ("D5000 system" for short), the domain name management function can only support remote service access, and is highly coupled with the existing D5000 remote service agent function. As the scale of the power grid continues to expand, the amount of data interaction between dispatching systems is increasing day by day. The existing domain name management function is difficult to meet the needs of the power system for wide-area message transmission and wide-area sharing of service information. Therefore, an independent, unified, and efficient power domain name management mechanism is urgently needed to support a wider range of wide-area dispatching services, realize unified management of domain nam...
