Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
To realize smooth control instruction issuing of the remote centralized control center, the following problems are solved: the instructions of the remote centralized control center can reach a public network through a forward isolator for transmission. The instruction transmitted to the wind power plant can enter a fan operation system of the wind power plant through the reverse isolator again, and therefore instruction issuing is completed. The whole process is required to meet the authority identity authentication of the instruction system. And enables instructions to arrive and execute reliably. The newly designed command control system does not affect the structure of the original system.
Two ends of the public network are respectively connected with the wind power plant and the remote centralized control center, and a forward isolator and a reverse isolator are respectively arranged at the two ends according to the data flow direction. However, in the existing system, because the system communication mechanism becomes complex in the mode of adopting the bilateral isolators, under the conditions of not strict early safety requirement and larger technical implementation difficulty, the flexible method for reducing the safety requirement is mostly adopted:
1) double-sided replacement of physical isolators with firewalls at the junction
And firewall is set at the interface between the wind power plant end and the centralized control center end and the public network, and the firewall is configured with a safety access rule to perform communication safety protection.
2) Double-side set-up communication encryptor for encrypting communication content
Encryption communication equipment is respectively arranged at two ends of a public network to immediately encrypt/decrypt communication contents between the wind power plant and the centralized control center
3) And encrypting the communication channel by adopting a VPN virtual network mode.
An access device of a VPN virtual network is arranged at a centralized control center end to carry out encryption limitation on a security authority account
4) By adding isolators on one side
Because the quantity of the centralized control center and the wind power field is in a one-to-many relationship, a set of forward isolation and reverse isolation is generally arranged in the centralized control center to send and receive data.
5) Mechanisms combining the above modes
Because the above modes can not meet the requirement of secondary safety protection of the power system, in order to improve the system safety, a communication mechanism adopting the above modes is combined at the same time.
The existing schemes all belong to flexible schemes and are remedial measures on the premise that technical conditions cannot meet safety requirements. With the stricter and stricter requirements of the country on the secondary safety protection of the production system, the schemes and the technologies have hidden dangers and the requirements of rectification.
The protection of preventing hot wall has and prevents that hot wall is breached, leads to the danger that whole system sinks.
The encryption machine is set up to enhance the privacy of the communication content, but the encryption machine only has an encryption function and has no capability of preventing intrusion.
Several other implementations do not completely isolate the communications of the public network from the physical design. There is a risk of damage from external intrusion.
The final solution is only the solution of setting forward isolators and reverse isolators at both ends of the public network channel. However, after the isolator is set, the internal communication mechanism of the software itself is broken, and the original normal data acquisition and control instruction issuing of the system can be restored by elaborate design.
Based on the problems, the method adopts a new thought and a new method, basically does not change the software operation communication mechanism of the original system under the condition of secondary safety protection isolation, adopts the mode of a transfer server and a transfer agent, and realizes reliable butt joint of two ends by designing corresponding transfer bridging software and respectively matching with the working modes of software systems at two ends of a wind power plant and a centralized control center. And moreover, a communication mechanism is optimized as much as possible, and the transmission capability is improved.

The operation principle of the remote control system of the wind turbine provided by the present application is described below with a specific embodiment, fig. 6 is a schematic structural diagram of another remote control system of a wind turbine according to the embodiment of the present application, and as shown in fig. 6, the remote control command system of the physical isolation condition is composed of 3 subsystems: a centralized control side subsystem, a transfer system and a substation side subsystem.
Under the condition of adding forward isolation and reverse isolation on both sides, a plurality of links are added between the substation system and the centralized control system for data forwarding and exchange. The remote control instruction system consists of three parts:
A. the substation side is connected with the system and deploys a corresponding program GAPClient _ sublist
B. The transfer system is provided with a transfer server and runs a corresponding program GAPClient _ transfer
C. The centralized control side is connected with the system and is used for deploying a corresponding program GAPServer
For the original working system of the wind farm substation and the centralized control center, the original system structure and working mode can be maintained under the support of the three functions. The specific remote control instruction functions and working modes are as follows:
a) the centralized control center initiates a control command to be issued to the centralized control side docking system GAPServer >;
b) the < centralized control side docking system GAPServer > gives an instruction to the < transfer system GAPClient _ transfer > through the forward isolator;
c) the < transfer system GAPClient _ transfer > analyzes and recombines the instruction, and delivers the instruction to < sub-station side docking system GAPClient _ sublit > through a reverse isolator, it needs to be explained that the data transmission of the reverse isolator has a set of subsystems, and the data transmission can be realized only when the strict requirements of the subsystems are completely met;
d) and finally, the substation side docking system GAPClient _ sublist gives the instruction information to the work system of the substation to complete instruction issuing.
After the command of the substation work system is successfully executed, the command execution result needs to be fed back to the centralized control center, and the feedback flow is opposite to the execution and delivery:
a) the < sub-station side docking system GAPClient _ sublist > is fed back to the < transfer system GAPClient _ transfer > through the forward isolation of the sub-station;
b) the format conversion and recombination are carried out on the transfer system GAPClient _ transfer, and then the information is fed back to the centralized control side butt joint system GAPServer through the master station reverse isolator;
c) and feeding back information to the centralized control working system.
In some optional embodiments of the present application, the remote control command is designed in a json format, where json is a lightweight data exchange format and a format with high readability, and supports various types of representations such as character strings, numbers, objects, and arrays.
According to an optional embodiment of the present application, the transmission mode of the remote control command and the feedback information takes 2 transmission forms under the physical isolation condition:
a) data packet form
The instruction content forms a communication packet that is transmitted between the transceiver programs, for example:
{"Name":"W3.DATAPOINT.A","Value":"10000","Type":1}
b) file form
The instruction content is written into a standard UTF-8 format file, and then the file transmission mode is used for transmitting the instruction content and the file.
In the command system, various application occasions are considered, an authentication mechanism is designed, in the application needing authentication, before a formal control command is sent, the authentication command can be sent, and after correct authentication feedback is obtained, the formal command is sent again.
The authentication command and the formal command are determined by a Type attribute in the command definition structure. The authentication information is initiated by the centralized control side and verified at the substation side:
an authentication instruction: { "Name": admin "," Value ": admin", "Type":2}
Authentication feedback: { "Name": admin "," Value ": addin", "Status": true "," Msg ": authentication pass" }
Programs < centralized control side docking system GAPServer > < transfer system GAPClient _ transfer > < substation side docking system GAPClient _ sublist > are all designed into a timing monitoring working mode, and in order to improve the sensitivity of an instruction system, the monitoring frequency of each subsystem is set to be 100 ms. The working properties are shown in the following table:
| module | Time spent on delivery | Feedback time | Total time consumption |
| GAPServer | 100ms | 100ms | 200ms |
| GAPClient_transfer | 1000ms | 1000ms | 2000ms |
| GAPClient_subsit | 100ms | 100ms | 200ms |
| Totaling: | 1400ms |
as can be seen from the above table, the process of instructing without authentication takes about 2.4 seconds, wherein 1.2 seconds is given, and 1.2 seconds is fed back. If pre-authentication is required, the entire instruction requires 2 round trips, requiring a period of around 4.8 seconds. It mainly takes time to be in the transit link. The file transmission mechanism of the reverse isolator in the transfer link has different performances of different models, and the performance of subsequent instruction issuing can be improved to a faster level under the continuous progress.
The technical scheme provided by the application designs a set of remote instruction system under the condition of meeting the secondary security and protection condition on the premise of not changing the working mode of the original system, and solves the safety problem of carrying out remote control on a production system on a public network private network. The designed transfer system and the virtual module have the characteristics of modularization, expandable functions and flexible deployment. The method has strong practicability and universality in real projects. With the continuous expansion of the new energy power scale, the system provides a reliable solution for the remote data transmission and the instruction control by using a large amount of cheap public network special lines, and can effectively reduce the difficulty, the cost and the flexibility of system construction.
The technical scheme provided by the application provides a concise interface and operation mode, and is easy to operate and deploy. Has very good effect on the use in actual projects. The concept and design of the scheme at present have originality in the field of wind power remote control.
