Description

Technical Field

[0001] The present invention relates to the technical field of communication architecture design, and particularly relates to a communication architecture and a communication method for network-source information interaction. Background Art

[0002] At present, there are mainly two ways to realize the communication between the power grid and the power plant. One is the way that the RTU (Remote Terminal Unit) master station on the first zone of the power grid side issues instructions to the RTU sub-station on the power plant side. This way is usually used to transmit AGC (Automatic Generation Control) control instructions and relevant data such as the actual power generation load of the power plant, and has a relatively high safety level. The other is that some power grid information is transmitted from the third zone of the power grid side to the third zone of the power plant side through a power dedicated line. The above two communication connection methods each have their own targeted objects, advantages and disadvantages. Among them, the first way is mainly for signals with strong real-time performance such as AGC control instructions, and has limited bandwidth. The second communication method is mainly for signals with weak real-time performance, but is not directly connected to the first zone of the power plant. The above two communication connection methods are relatively mature. However, at present, new requirements for network-source coordinated operation emerge, that is, the mutual communication requirements between the power grid and the power plant are more vigorous. Under this network-source coordinated operation mode, it is required to have high reliability of operation and also require that power grid information can act on the first zone of the power plant side. Therefore, any one of the above two methods is difficult to simultaneously meet the new requirements for network-source coordinated operation, and there is an urgent need to expand a new network-source coordinated communication architecture.

[0018] See Figure 1, an embodiment of the present invention provides a communication architecture for network-source information interaction, including a dispatching control system 211, a first auxiliary server 222, a second auxiliary server 123, a third auxiliary server 115, a unidirectional isolation gateway, an optimization control cabinet 114, and a distributed control system 111; the third auxiliary server 115 and the optimization control cabinet 114 are located in Area 1 on the power plant side, the dispatching control system 211 is located in Area 1 on the power grid side 210, the first auxiliary server 222 is located in Area 3 on the power grid side 220, and the second auxiliary server 123 is located in Area 3 on the power plant side 120; the unidirectional isolation gateway is located between Area 1 and Area 3 on the power plant side; the power plant side 100 includes Area 1 on the power plant side and Area 3 on the power plant side 120, and the power grid side 200 includes Area 1 on the power grid side 210 and Area 3 on the power grid side 220; See Figure 1 In the dashed part in [reference], in the order of the signal transmission direction, the dispatching control system 211, the first auxiliary server 222, the second auxiliary server 123, the unidirectional 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 according to the current spot clearing data and the first output signal, and 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 dispatching control system 211; Similarly see Figure 1 In the dashed part in [reference], in the order of 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; in the second auxiliary server 123 is used to obtain the second status signal according to the second output signal, and 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 Area 1 on the power plant side 110.

[0019] By setting the first communication line of the unidirectional isolation gateway and the optimization control cabinet 114, the information on the power grid side can act on Area 1 on the power plant side and be used for auxiliary production on the basis of ensuring operation reliability, providing a feasible and reliable path for the information on the power grid side to act on Area 1 on the power plant side. Through the second communication line, the relevant information after information processing with Area 1 on the power plant side can be displayed in Area 3 on the power grid side 220 to assist the power grid dispatching operation personnel to make adjustments, meet the new network-source coordinated operation requirements, and add a new implementation way for the mutual perception between the power grid side and the power plant side on the current basis, making full use of the power dedicated network in Area 3 on the power grid side 220 to support the information intertransmission of larger-capacity data. At the same time, since neither the first communication line nor the second communication line passes through the RTU (Remote Terminal Unit), the security of the entire control system can be guaranteed without affecting the normal production operation under the original communication method.

[0020] In some of these embodiments, the decentralized control system 111 is used to collect the real-time operation data of the current unit and send it to the three areas on the power plant side 120 and the first area on the grid side 210 respectively. The real-time operation data includes first real-time operation data and second real-time operation data. The first real-time operation data is the real-time operation data transmitted to the first area on the grid side 210, and the second real-time operation data is the real-time operation data transmitted to the three areas on the power plant side 120. That is, the real-time operation data is the status signal of the first area on the power plant side 110. Among them, the real-time operation data is transmitted to the first area on the grid side 210 through the RTU communication method as the first real-time operation data; Specifically, an RTU master station 212 is set in the first area on the grid side 210, and an RTU slave station 112 is set in the first area on the power plant side 110. There are two-way signal connections between the dispatching control system 211 and the RTU master station 212, between the RTU master station 212 and the RTU slave station 112, and between the RTU slave station 112 and the decentralized control system 111 respectively. Among the real-time operation data sent by the decentralized control system 111, the first real-time operation data is transmitted to the dispatching control system 211 after passing through the RTU slave station 112 and the RTU master station 212 in sequence; In some of these embodiments, a first database 113 is also set in the first area on the power plant side 110, and a second database 122 is also set in the three areas on the power plant side 120; There are one-way signal connections between the decentralized control system 111 and the first database 113, and between the first database 113 and the second database 122 respectively. The second output signal is transmitted to the second database 122 through the first database 113. The second auxiliary server 123 obtains the second output signal through the second database 122. That is, the second real-time operation data is transmitted to the second database 122 located in the three areas on the power plant side 120 through the first database 113. The database transmission method uses a dedicated interface and encryption technology to ensure the security of data during transmission, and can realize the comprehensive management and efficient utilization of the second real-time operation data, providing strong support for the intelligent operation and decision-making of the power plant.

[0021] The dispatching control system 211 is used to obtain dispatching operation data according to the first real-time operation data, and is used to send the first real-time operation data and the dispatching operation data to the first auxiliary server 222 respectively; The first auxiliary server 222 is used to obtain the current spot clearing data, is used to obtain a first status signal according to the dispatching operation data, the first real-time operation data and the current spot clearing data, and is used 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 an auxiliary production decision according to the first status signal; The second auxiliary server 123 is used to obtain a second status signal according to the second real-time operation data, and to transmit the second status signal to the first auxiliary server 222 along a second communication line.

[0022] The first auxiliary server 222 processes the current spot clearing data, dispatching operation data, and first real-time operation data to obtain a 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 optimization control cabinet 114 processes the first status signal to obtain an auxiliary production decision, realizing the automatic operation control of the first area 110 on the power plant side after perceiving the power grid information; The second auxiliary server 123 processes the second real-time operation data, completes the real-time calculation and perception of the operation status of the first area 110 on the power plant side, and reversely transmits the calculation result to the first auxiliary server 222 located in the third area 220 on the power grid side along the second communication line, completes the display of relevant information, and assists the power grid dispatching operation personnel to carry out operation adjustment.

[0023] In addition, edge computing can be realized by setting the first auxiliary server 222 and the second auxiliary server 123, that is, the first auxiliary server 222 only processes or calculates the data related to production control, and the second auxiliary server 123 only processes or calculates the information related to the power grid, and then realizes the communication of a small amount of data, which can effectively reduce the amount of data to be transmitted and improve the transmission speed.

[0024] In some of these embodiments, the dispatching control system 211 is further used to send dispatching operation data to the distributed control system 111, and the distributed control system 111 is located in the first area 110 on the power plant side; The optimization control cabinet 114 is further used to send the decision to the distributed control system 111; The distributed control system 111 is further used to obtain the current control instruction according to the dispatching operation data and the auxiliary production decision, and to control the current unit according to the current control instruction.

[0025] The distributed control system 111 processes the dispatching operation data and the auxiliary production decision, fully considers the information of the dispatching agency and the power grid side, and meets the requirements of network-source coordination.

[0026] In some of these embodiments, a main server 221 is further set in the third area 220 on the power grid side, and a shift supervisor switch 121 is further set in the third area 120 on the power plant side; The existing communication architecture between the power grid and the power plant is as Figure 2As shown in the figure, the dispatching control system 211 in the first area 210 on the grid side generates dispatching operation data. The dispatching operation data is transmitted to the distributed control system 111 after passing through the RTU master station 212 and the RTU slave station 112 in sequence, completing the operation control of the current unit. At the same time, a main server 221 is set in the third area 220 on the grid side. The main server 221 receives the dispatching operation data and the current spot clearing data from the dispatching control system 211, and transmits them to the shift supervisor switch 121 located in the third area 120 on the power plant side for display respectively. The distributed control system 111 in the first area 110 on the power plant side is connected to the first database 113. The first database 113 is located in the first area 110 on the power plant side, and the distributed control system 111 transmits signals to the first database 113 unidirectionally. The first database 113 transmits the data to the second database 122 located in the third area 120 on the power plant side. The existing communication architecture only performs production control on the current unit through the dispatching operation data of the dispatching control system 211. The dispatching operation data and the current spot clearing data are only displayed on the shift supervisor switch 121, and the coordinated operation of the grid and the power source, that is, the mutual communication between the power grid and the power plant, cannot be achieved.

[0027] The first communication line further 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, an optical - electrical converter 125 is set 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 uses the Modbus RTU communication protocol based on the 485 serial port; the combination of the optical - electrical converter and the Modbus RTU communication protocol based on the 485 serial port can realize the signal communication between the electrical network and the thermal network; In the prior art, the shift supervisor switch 121, the second database 122 and the second auxiliary server 123 in the third area 120 on the power plant side belong to different network partitions. Among them, the shift supervisor switch 121 belongs to the electrical control system network partition. The shift supervisor switch 121 is connected to the main server 221 through the CMS system and the router 124 via optical fiber A. The CMS system and the router 124 are set in the third area 120 on the power plant side; while the second database 122 and the second auxiliary server 123 belong to the thermal control system network partition. The thermal control system network partition further includes the first database 113 and the distributed control system 111 in the first area 110 on the power plant side. The electrical control system network partition and the thermal control system network partition are isolated from each other. See Figure 4 , so the mutual transmission of grid - source information cannot be achieved.

[0028] To achieve the mutual transmission of grid-side and power plant-side grid-source information, an optical-electric converter 125 is set between the second auxiliary server 123 in the network partition of the electrical control system and the shift supervisor switch 121 in the network partition of the thermal control system. The optical-electric converter 125 transmits information to and from the shift supervisor switch 121 through the spare optical fiber core B of the shift supervisor switch 121, and the optical-electric converter 125 transmits information to and from the second database 122 through network cable C.

[0029] The second communication line further includes a server and the 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. An optical-electric converter is set 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 uses the Modbus RTU communication protocol based on the 485 serial port.

[0030] The main server 221 and the shift supervisor's switch 121 are both basic network architectures existing in the power plant. On the basis of not affecting the operation of the original system, two-way communication is carried out between the first auxiliary server 222 and the main server 221, and the communication protocol for signal transmission between the first auxiliary server 222 and the main server 221 adopts the IEC104 protocol. On the basis of the existing system, two-way communication is newly added between the main server 221 and the shift supervisor's switch 121, and the newly added two-way communication between the main server 221 and the shift supervisor's switch 121 adopts the IEC104 protocol. Two-way communication is carried out between the shift supervisor's switch 121 and the second auxiliary server 123, and signal communication between the electrical network and the thermal control network is realized through an optical-electric converter in combination with the Modbus RTU communication protocol based on the 485 serial port. One-way communication is carried out between the second auxiliary server 123 and the one-way isolation gateway, and the signal transmission direction is from the second auxiliary server 123 to the one-way isolation gateway. The communication protocol for signal transmission between the second auxiliary server 123 and the one-way isolation gateway adopts TCP / IP network communication. One-way communication is carried out between the one-way isolation gateway and the third auxiliary server 115, and the signal transmission direction is from the one-way isolation gateway to the third auxiliary server 115. The communication protocol for signal transmission between the one-way isolation gateway and the third auxiliary server 115 adopts TCP / IP network communication. One-way communication is carried out between the third auxiliary server 115 and the optimization control cabinet 114, and the signal transmission direction is 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 adopts the Modbus RTU communication protocol based on the 485 serial port. The optimization control cabinet 114 transmits the signal unidirectionally to the distributed control system 111. A hardwired connection is adopted between the optimization control cabinet 114 and the distributed control system 111 to realize the mutual perception and information intertransmission of the grid side state and the power plant side state, with high reliability and no impact on the operation safety of the original system, providing a feasible path for the grid information to act on the power plant side area 110.

[0031] See Figure 3 , the embodiment of the present invention further provides a communication method, which is realized by using the communication architecture of network-source information interaction, and includes the following steps: In the grid side area 210, the dispatching control system 211 obtains dispatching operation data according to the received real-time operation data; The dispatching control system 211 respectively transmits the real-time operation data and the dispatching operation data to the first auxiliary server 222 located in the grid side area 220; In the grid side area 220, the first auxiliary server 222 collects the current spot clearing data; In the grid side area 220, the first auxiliary server 222 obtains the first status signal according to the dispatching operation data, the real-time operation data and the current spot clearing data; The first status signal is transmitted from the third zone 220 on the grid side to the optimization control cabinet 114 located in the first zone 110 on the power plant side via the first communication line through the third zone 120 on the power plant side. Within the first zone 110 on the power plant side, the optimization control cabinet 114 obtains an auxiliary production decision based on the first status signal. Within the third zone 120 on the power plant side, the second auxiliary server 123 obtains a second status signal based on the received real-time operation data. The second status signal is transmitted from the third zone 120 on the power plant side to the first auxiliary server 222 located in the third zone 220 on the grid side via the second communication line.

[0032] The first auxiliary server 222 in the third zone 220 on the grid side obtains the first status signal through processing, and after transmitting the first status signal to the first zone 110 on the power plant side through the first communication line with a one-way isolation gateway, it can obtain an auxiliary production decision. It can apply the information on the grid side to the first zone 110 on the power plant side for auxiliary production while ensuring operation reliability, providing a feasible and reliable path for the information on the grid side to act on the first zone 110 on the power plant side. The second auxiliary server 123 in the third zone 120 on the power plant side obtains the second status signal through processing, and the second status signal can be displayed in the third zone 220 on the grid side through the second communication line to assist the grid dispatching operators in making adjustments to meet the new grid-source coordinated operation requirements. Since neither the first communication line nor the second communication line passes through the RTU, the security of the entire control system can be ensured without affecting the normal production operation under the original communication method.

[0034] By setting the first communication line of the unidirectional isolation gateway and obtaining the auxiliary production decision after the first state signal is transmitted to the first zone 110 on the power plant side through the first communication line, the information on the grid side can act on the first zone 110 on the power plant side and be used for auxiliary production on the basis of ensuring operation reliability, providing a feasible and reliable path for the information on the grid side to act on the first zone 110 on the power plant side. Through the second communication line, the relevant information after information processing with the first zone 110 on the power plant side can be displayed in the three - zone 220 on the grid side to assist the grid dispatching operation personnel in making adjustments and meeting the new requirements for coordinated operation of the power grid and power sources. Since neither the first communication line nor the second communication line passes through the RTU, the security of the entire control system can be guaranteed without affecting the normal production operation under the original communication mode.
