Description

Technical Field

[0001] This invention relates to the field of communication architecture design technology, specifically to a communication architecture and communication method for network-source information interaction. Background Technology

[0002] Currently, there are two main methods for communication between the power grid and power plants. One method involves the power grid's master station (RTU) sending commands to the power plant's RTU substation. This method is typically used to transmit AGC (Automatic Generation Control) commands and data related to the power plant's actual load, offering a high level of security. The other method involves the power grid's third zone transmitting some grid information to the power plant's third zone via dedicated power lines. Each of these communication methods has its own target audience and advantages / disadvantages. The first method primarily targets signals with high real-time requirements, such as AGC control commands, but has limited bandwidth. The second method primarily targets signals with lower real-time requirements but is not directly connected to the power plant's first zone. These two communication methods are relatively mature. However, new demands for grid-source coordinated operation are emerging, meaning the need for mutual communication between the power grid and power plants is becoming increasingly strong. This grid-source coordinated operation requires both high operational reliability and the ability for grid information to be applied to the power plant's first zone. Therefore, neither of the above two methods can simultaneously meet the new network-source coordination operation requirements, and there is an urgent need to expand to a new network-source coordination communication architecture. Summary of the Invention

[0019] In some embodiments, the communication protocol for signal transmission between the first auxiliary server and the main server adopts the IEC104 protocol.

[0020] In some embodiments, a photoelectric converter is provided between the second auxiliary server and the shift supervisor switch.

[0022] When the second status signal is input to the duty officer's switch, it is transmitted via the Modbus RTU communication protocol based on the 485 serial port.

Through the second communication line, relevant information processed from Zone 1 of the power plant can be displayed in Zone 3 of the power grid, assisting power grid dispatching personnel in making adjustments and meeting new requirements for coordinated grid-source operation. Furthermore, since neither the first nor the second communication line passes through the RTU, the security of the entire control system is guaranteed, and normal production operation under the original communication method is not affected.

Detailed Implementation

[0046] To clearly illustrate the technical features of this solution, the implementation methods of this application will be described in detail below with reference to the accompanying drawings and embodiments. This will allow for a full understanding and implementation of how this application uses technical means to solve technical problems and achieve corresponding technical effects. The embodiments of this application and the various features within them can be combined with each other without conflict, and the resulting technical solutions are all within the protection scope of this application.

[0047] See Figure 1 This invention provides a communication architecture for network-source information interaction, including a dispatch control system 211, a first auxiliary server 222, a second auxiliary server 123, a unidirectional isolation gateway, an optimization control cabinet 114, and a distributed control system 111. The optimization control cabinet 114 is located in Zone 1 on the power plant side, the dispatch control system 211 is located in Zone 10 on the power grid side, the first auxiliary server 222 is located in Zone 30 on the power grid side, and the second auxiliary server 123 is located in Zone 30 on the power plant side. The unidirectional isolation gateway is located between Zone 1 and Zone 3 on the power plant side. The power plant side 100 includes Zone 1 and Zone 3 on the power plant side 120, and the power grid side 200 includes Zone 110 and Zone 3 on the power grid side 220.

[0048] See Figure 1 In the dashed section, along the signal transmission direction, the dispatch control system 211, the first auxiliary server 222, the second auxiliary server 123, the one-way isolation gateway, and the optimization control cabinet 114 form a first communication line. In the first communication line, the first auxiliary server 222 is used to obtain the current spot clearing data and the first output signal, and obtain the first status signal based on the current spot clearing data and the first output signal. The first status signal is transmitted from the first auxiliary server 222 to the optimization control cabinet 114 along the first communication line. The first output signal is the output signal of the dispatch control system 211.

[0049] See also Figure 1 In the dashed section, along the signal transmission direction, the distributed control system 111, the second auxiliary server 123, and the first auxiliary server 222 form a second communication line. The second communication line transmits the signal from the power plant side zone 110 through the power plant side zone 3 120 to the power grid side zone 3 220. The second auxiliary server 123 is used to obtain the second status signal based on the second output signal. The second status signal is transmitted from the second auxiliary server 123 to the first auxiliary server 222 along the second communication line. The second output signal is the status signal of the power plant side zone 110.

[0050] By setting up a one-way isolation gate and optimizing the first communication line of the control cabinet 114, information from the power grid side can be applied to the power plant's first zone 110 for auxiliary production while ensuring operational reliability. This provides a feasible and reliable path for information from the power grid side to be applied to the power plant's first zone 110. The second communication line enables the display of information processed by the power plant's first zone 110 in the power grid's third zone 220, assisting power grid dispatching personnel in making adjustments and meeting new requirements for coordinated grid-source operation. This adds a new means of mutual sensing between the power grid side and the power plant side, fully utilizing the dedicated power grid network of the power grid's third zone 220 to support larger-capacity data transmission. Furthermore, since neither the first nor the second communication line passes through an RTU (Remote Terminal Unit), the security of the entire control system is guaranteed, and normal production operation under the original communication method is not affected.

[0051] In some embodiments, the distributed control system 111 is used to collect real-time operating data of the current unit and send it to the power plant side zone 3 120 and the grid side zone 1 210 respectively. The real-time operating data includes first real-time operating data and second real-time operating data. The first real-time operating data is the real-time operating data transmitted to the grid side zone 1 210, and the second real-time operating data is the real-time operating data transmitted to the power plant side zone 3 120. That is, the real-time operating data is the status signal of the power plant side zone 110. Among them, the real-time operating data transmitted to the grid side zone 1 210 via RTU communication is the first real-time operating data.

[0052] Specifically, an RTU master station 212 is set up in Zone 10 on the power grid side, and an RTU substation 112 is set up in Zone 10 on the power plant side. The dispatch control system 211 and the RTU master station 212, the RTU master station 212 and the RTU substation 112, and the RTU substation 112 and the distributed control system 111 are respectively connected by bidirectional signals. In the real-time operation data sent by the distributed control system 111, the first real-time operation data is transmitted to the dispatch control system 211 after passing through the RTU substation 112 and the RTU master station 212 in sequence.

[0053] In some embodiments, the power plant side zone 110 is further provided with a first database 113, and the power plant side zone 3 120 is further provided with a second database 122.

[0054] The distributed control system 111 is connected to the first database 113 and the first database 113 is connected to the second database 122 by unidirectional signals. The second output signal is transmitted from the first database 113 to the second database 122. The second auxiliary server 123 obtains the second output signal through the second database 122. That is, the second real-time operating data is transmitted from the first database 113 to the second database 122 located in the third zone 120 of the power plant. The database transmission method uses a dedicated interface and encryption technology to ensure the security of the data during transmission. It can realize the comprehensive management and efficient utilization of the second real-time operating data, and provide strong support for the intelligent operation and decision-making of the power plant.

[0055] The dispatch control system 211 is used to obtain dispatch operation data based on the first real-time operation data, and to send the first real-time operation data and the dispatch operation data to the first auxiliary server 222 respectively;

[0056] The first auxiliary server 222 is used to acquire current spot clearing data, to obtain a first status signal based on scheduling operation data, first real-time operation data and current spot clearing data, and to transmit the first status signal to the optimization control cabinet 114 along the first communication line; the optimization control cabinet 114 is used to obtain auxiliary production decisions based on the first status signal.

[0057] The second auxiliary server 123 is used to obtain a second status signal based on the second real-time operating data, and to transmit the second status signal to the first auxiliary server 222 along the second communication line.

[0058] The first auxiliary server 222 processes the current spot clearing data, scheduling operation data and first real-time operation data to obtain the first status signal, completes the real-time calculation and perception of the power grid operation status, realizes the logic of transmission, configuration interface, switching, etc. through the first communication line, and the first status signal is processed by the optimization control cabinet 114 to obtain auxiliary production decisions, realizing the automatic operation control of the power plant side zone 110 after sensing the power grid information.

[0059] The second auxiliary server 123 processes the second real-time operating data, completes the real-time calculation and perception of the operating status of the power plant side zone 110, and transmits the calculation results in reverse along the second communication line to the first auxiliary server 222 located in the power grid side zone 3 220, completes the display of relevant information, and assists the power grid dispatching and operation personnel in making operation adjustments.

[0060] Furthermore, edge computing can be achieved by setting up a first auxiliary server 222 and a second auxiliary server 123. That is, the first auxiliary server 222 only processes or calculates data related to production control, and the second auxiliary server 123 only processes or calculates information related to the power grid, thereby enabling communication of a small amount of data, which can effectively reduce the amount of data transmitted and improve the transmission speed.

[0061] In some embodiments, the dispatch control system 211 is also used to send dispatch operation data to the distributed control system 111, which is located in Zone 110 on the power plant side.

[0062] The optimized control cabinet 114 is also used to send decisions to the distributed control system 111;

[0063] The distributed control system 111 is also used to obtain current control commands based on scheduling operation data and auxiliary production decisions, and to control the current unit based on the current control commands.

[0064] The distributed control system 111 processes scheduling operation data and auxiliary production decision-making, fully considers information from the dispatching agency and the power grid side, and meets the needs of grid-source coordination.

[0065] In some embodiments, the power grid side zone 220 is also equipped with a main server 221, and the power plant side zone 120 is also equipped with a shift supervisor switch 121.

[0066] The existing communication architecture between power grids and power plants, such as Figure 2 As shown, the dispatch control system 211 in the first zone 210 of the power grid generates dispatch operation data. The dispatch operation data is transmitted sequentially through the RTU master station 212 and the RTU substation 112 to the distributed control system 111 to complete the operation control of the current unit. At the same time, a master server 221 is set up in the third zone 220 of the power grid. The master server 221 receives the dispatch operation data and the current spot clearing data from the dispatch control system 211 and transmits them to the shift operator switch 121 located in the third zone 120 of the power plant for display. The distributed control system 111 in the first zone 110 of the power plant is connected to the first database 113. The first database 113 is located in the first zone 110 of the power plant, and the distributed control system 111 transmits signals unidirectionally to the first database 113. The first database 113 transmits data to the second database 122 located in the third zone 120 of the power plant. The existing communication architecture only controls the production of the current unit through the scheduling and operation data of the scheduling and control system 211. The scheduling and operation data and the current spot clearing data are only displayed on the shift supervisor's switch 121, which cannot realize the coordinated operation of the grid and the power plant, i.e., the mutual communication between the grid and the power plant.

[0067] The first communication line also includes a main server 221 and a shift supervisor switch 121. Along the signal transmission direction, the main server 221 and the shift supervisor switch 121 are sequentially arranged between the first auxiliary server 222 and the second auxiliary server 123. The communication protocol for signal transmission between the first auxiliary server 222 and the main server 221 adopts the IEC104 protocol. In some embodiments, a photoelectric converter 125 is arranged between the second auxiliary server 123 and the shift supervisor switch 121. When the first status signal is output through the shift supervisor switch 121, it is transmitted via a Modbus RTU communication protocol based on a 485 serial port. The photoelectric converter, combined with the Modbus RTU communication protocol based on a 485 serial port, can realize signal communication between the electrical network and the thermal network.

[0068] In the existing technology, the shift supervisor switch 121, the second database 122, and the second auxiliary server 123 within the third zone 120 of the power plant belong to different network partitions. The shift supervisor switch 121 belongs to the electrical control system network partition, and is connected to the main server 221 via fiber optic A through the CMS system and router 124, which is located within the third zone 120 of the power plant. The second database 122 and the second auxiliary server 123 belong to the thermal control system network partition, which also includes the first database 113 and the distributed control system 111 within the first zone 110 of the power plant. The electrical control system network partition and the thermal control system network partition are isolated from each other. (See [link to relevant documentation]). Figure 4 Therefore, it is impossible to achieve mutual transmission of network source information.

[0069] To enable the mutual transmission of grid source information between the grid side and the power plant side, a photoelectric converter 125 is installed between the second auxiliary server 123 located in the electrical control system network partition and the shift operator switch 121 located in the thermal control system network partition. The photoelectric converter 125 transmits information with the shift operator switch 121 through the spare fiber core B of the shift operator switch 121. The photoelectric converter 125 transmits information with the second database 122 through the network cable C.

[0070] The second communication line also includes a main server 221 and a shift supervisor switch 121. Along the signal transmission direction, the shift supervisor switch 121 and the main server 221 are sequentially arranged between the second auxiliary server 123 and the first auxiliary server 222. A photoelectric converter is installed between the second auxiliary server 123 and the shift supervisor switch 121. When the second status signal is input to the shift supervisor switch 121, it is transmitted via the Modbus RTU communication protocol based on the 485 serial port.

[0071] Both the main server 221 and the shift supervisor's switch 121 are part of the power plant's existing network infrastructure. Without affecting the operation of the original system, the first auxiliary server 222 communicates bidirectionally with the main server 221, using the IEC104 protocol for signal transmission. Bidirectional communication is added between the main server 221 and the shift supervisor's switch 121, also using the IEC104 protocol. Furthermore, bidirectional communication is established between the shift supervisor's switch 121 and the second auxiliary server 123 via a photoelectric converter combined with Modbus based on a 485 serial port. The RTU communication protocol enables signal communication between the electrical network and the thermal network. The second auxiliary server 123 communicates unidirectionally with the one-way isolation gate, with signal transmission from the second auxiliary server 123 to the one-way isolation gate. The communication protocol between the second auxiliary server 123 and the one-way isolation gate uses TCP / IP network communication. The one-way isolation gate also communicates unidirectionally with the third auxiliary server 115, with signal transmission from the one-way isolation gate to the third auxiliary server 115. The communication protocol between the one-way isolation gate and the third auxiliary server 115 uses TCP / IP network communication. The third auxiliary server 115 communicates unidirectionally with the optimization control cabinet 114, with signal transmission from the third auxiliary server 115 to the optimization control cabinet 114. The signal transmission between the third auxiliary server 115 and the optimization control cabinet 114 uses Modbus based on a 485 serial port. The RTU communication protocol optimizes the unidirectional transmission of signals from the control cabinet 114 to the distributed control system 111. The optimized control cabinet 114 and the distributed control system 111 are hard-wired to realize mutual perception and information exchange between the grid side status and the power plant side status. It has high reliability and does not affect the operation safety of the original system, providing a feasible path for grid information to act on the power plant side zone 110.

[0072] See Figure 3 The present invention also provides a communication method, which is implemented using a communication architecture for interaction between network and source information, including the following steps: within a zone 210 on the power grid side, the dispatch control system 211 obtains dispatch operation data based on the received real-time operation data;

[0073] The dispatch control system 211 transmits real-time operation data and dispatch operation data to the first auxiliary server 222 located in the third zone 220 of the power grid side, respectively;

[0074] Within zone 220 on the power grid side, the first auxiliary server 222 collects current spot clearing data;

[0075] Within the third zone 220 on the power grid side, the first auxiliary server 222 obtains the first status signal based on the scheduling operation data, real-time operation data, and current spot clearing data;

[0076] The first status signal is transmitted along the first communication line from the power grid side zone 3 220 through the power plant side zone 3 120 to the optimization control cabinet 114 located in the power plant side zone 110.

[0077] Within Zone 110 on the power plant side, the optimization control cabinet 114 obtains auxiliary production decisions based on the first state signal;

[0078] Within Zone 120 on the power plant side, the second auxiliary server 123 obtains the second status signal based on the received real-time operating data;

[0079] The second status signal is transmitted along the second communication line from the power plant side zone 120 to the first auxiliary server 222 located in the power grid side zone 220.

[0080] The first auxiliary server 222, located in the power grid-side zone 3 220, obtains the first status signal through processing. This signal is then transmitted to the power plant-side zone 1 110 via a first communication line with a unidirectional isolation gate, enabling auxiliary production decisions. This allows information from the power grid side to be applied to the power plant-side zone 1 110 for auxiliary production while ensuring operational reliability, providing a feasible and reliable path for this information. The second auxiliary server 123, located in the power plant-side zone 3 120, obtains the second status signal through processing. This signal is then displayed in the power grid-side zone 3 220 via a second communication line, assisting power grid dispatching personnel in making adjustments to meet new grid-source coordination requirements. Since neither the first nor the second communication line passes through the RTU, the safety of the entire control system is guaranteed, and normal production operation under the existing communication method is not affected.

[0081] This invention also provides a communication method, including the following steps: within a grid-side zone 210, obtaining scheduling operation data based on received first real-time operation data, wherein the first real-time operation data is real-time operation data transmitted by a power plant-side zone 110;

[0082] The first real-time operation data and the dispatch operation data were respectively transmitted to the power grid side, Zone 3, 220.

[0083] Collect current spot clearing data within Zone 220 on the power grid side;

[0084] Within Zone 220 on the power grid side, the first status signal is obtained based on dispatch operation data, first real-time operation data, and current spot clearing data;

[0085] The first status signal is transmitted along the first communication line from the power grid side zone 220 through the power plant side zone 120 and the one-way isolation gate to the power plant side zone 110.

[0086] Within Zone 110 on the power plant side, auxiliary production decisions are obtained based on the first state signal;

[0087] Within the third zone 120 on the power plant side, a second status signal is obtained based on the received second real-time operation data, which is the real-time operation data transmitted from the first zone 110 on the power plant side.

[0088] The second communication line transmits the signal from the power plant side zone 110 through the power plant side zone 3 120 to the power grid side zone 3 220. The second status signal is transmitted along the second communication line from the power plant side zone 3 120 to the power grid side zone 3 220.

[0089] By setting up a first communication line for a unidirectional isolation gate, and transmitting the first status signal to Zone 110 on the power plant side via this first communication line, auxiliary production decisions can be obtained. This allows information from the grid side to be applied to Zone 110 on the power plant side for auxiliary production while ensuring operational reliability. It provides a feasible and reliable path for grid-side information to be applied to Zone 110 on the power plant side. Through the second communication line, relevant information processed by Zone 110 on the power plant side can be displayed in Zone 3 on the grid side, assisting grid dispatching personnel in making adjustments to meet new grid-source coordination requirements. Since neither the first nor the second communication line passes through the RTU, the safety of the entire control system is guaranteed, and normal production operation under the original communication method is not affected.
