Description
Technical Field
The invention relates to the technical field of power dispatching station state monitoring, in particular to a remote station topological online state monitoring method and system for power dispatching.
Background
The power dispatching is an effective management means for ensuring safe and stable operation of a power grid, supplying power to the outside reliably and carrying out various power production operations in order. With the development of computer technology, network communication technology and field bus technology, power scheduling tends to be automated gradually in the development process of the power scheduling, the scheduling between a central office station and each remote station is more and more perfect, in the automatic power scheduling process, in order to guarantee the communication between the remote station and the central office station, the power scheduling between the central office station and the remote station is usually realized on the basis of a power communication private network and further by adopting a proper scheduling number-placing mode, and a scheduling telephone is used as the most direct means for commanding power scheduling command, and requires high reliability of access operation between the central office station and the remote station and including remote station terminal equipment, and in many cases, a worker cannot master the power scheduling in time because the remote station terminal equipment can find faults when needing to be used. Therefore, the remote sites are managed in a comprehensive mode, the running state of the remote sites is monitored on line, faults or abnormalities of terminal equipment running of the remote sites are found in time, and high reliability of power dispatching achieved by applying a dispatching number-marking mode between the local central station and the remote sites is guaranteed.
The prior art discloses a remote visual monitoring method for a network topology of an electric power monitoring system, which realizes the instant check of the network topology in the environment of a power plant and a transformer substation which are relatively closed by the electric power monitoring system through the remote retrieval and restoration of the network topology of the power plant or the station at the remote end of the electric power monitoring system, meanwhile, the remote visual monitoring and early warning of the network topology structure and the system operation condition of the station end of the power plant and the station end of the electric power monitoring system are realized by receiving the operation state and the network safety data of the equipment of the station in real time, correlating the operation state and the network safety data to the topology portrait of a network safety management center in time and dynamically refreshing the node state of each equipment of the topology portrait, thereby ensuring the processing efficiency of the station end of the electric power monitoring system to the emergency to a great extent. However, in practical situations, remote sites are relatively dispersed and have a wide range, especially, the positions of some unmanned sites are remote, even the power integrated data network cannot cover, if the operation data of the remote sites and the terminal access devices thereof are remotely retrieved directly through the network management center of the central office station, the received retrieved data often has a large deviation from the actual data, if the network is abnormal or the data has a problem in the transmission process, the received data does not have a reference value, unforeseen faults or abnormalities are more likely to occur, the communication reliability between the central office station and the remote sites cannot be ensured, and if a worker judges the operation states of the remote sites and the terminal access devices by using the error data, the wrong result is obtained, and the power scheduling is more difficult to be planned.
Disclosure of Invention
In order to solve the problems of scattered distribution, wide range and remote positions of remote sites and difficulty in online monitoring and overall management in power scheduling, the invention provides a remote site topological online state monitoring method and system for power scheduling.
In order to achieve the technical effects, the technical scheme of the invention is as follows:
a remote site topological online state monitoring method for power scheduling comprises the following steps:
s1, preliminarily dividing remote sites into different initial site groups;
s2, further screening remote stations in the same initial station group to obtain a final station group;
s3, selecting a main remote station from the final station group, taking a remote station except the main remote station as a slave remote station, connecting the main remote station with a central office station, and connecting the main remote station with the slave remote station in each final station group;
s4, respectively confirming the link conditions between the main remote station and the central station monitoring platform of the local side in each final station group and between the main remote station and the slave remote station in each final station group in a dispatching and number-releasing response mode;
s5, each main remote station transmits topological connection data of remote stations in a final station group to a local central station monitoring platform, and the local central station monitoring platform images the topological connection data of each remote station to form a topological connection mapping image;
s6, defining normal operation indexes of each remote station and terminal access equipment thereof, endowing each operation index of each imaged remote station and terminal access equipment thereof with a reference standard, and setting a reference threshold error of each index;
s7, setting the central station of the local end, the remote station and the terminal access equipment of the remote station to start to operate, packaging the self operation log by the slave remote station of each final station group and transmitting the self operation log to the master remote station, packaging the self operation log by the master remote station and transmitting the self operation log and the operation log transmitted by each slave remote station to the monitoring platform of the central station of the local end;
s8, the central local station monitoring platform receives and analyzes the packed operation logs, compares each operation index in the operation logs of each remote station with a reference standard, and judges whether the distance between each operation index and the reference standard does not exceed the reference threshold error of each index, if so, the remote station is in a normal operation state; otherwise, an abnormal operation site exists, and the index with the distance from the reference standard exceeding the corresponding index reference threshold value error and the corresponding remote site are screened out from the topological connection mapping image and serve as the abnormal site.
In the technical scheme, the characteristics of dispersion, wide range and remote position of remote stations are considered, the remote stations are preliminarily divided into different initial station groups, all the remote stations are disassembled in a group form, then the remote stations in the initial station groups are further refined and screened, final station groups are divided, a main remote station is selected from the final station groups to be connected with a central office station, and the main remote station in each final station group is connected with a slave remote station, which is equivalent to using the main remote station as a relay, so that the communication pressure of the central office station directly connected with each remote station is reduced, and the communication reliability is improved; and on the premise of confirming the link condition between the main remote station and the central office station and the link condition between the main remote station and the slave remote station in each final station group, the method is divided into two layers: the method comprises the steps of firstly transmitting topological connection data of remote stations to form topological connection mapping images, secondly, after standard operation indexes of each remote station and terminal access equipment of the remote station are determined, the remote stations package operation logs of the remote stations and send the operation logs to a central office station monitoring platform, the central office station monitoring platform screens out indexes with the distance from a reference standard exceeding a corresponding index reference threshold error and corresponding remote stations in the topological connection mapping images through analysis and comparison, on-line monitoring is conducted on the operation states of the remote stations on the premise that overall management of the remote stations is achieved, and reliability of electric power scheduling is further guaranteed through a scheduling number releasing mode between the central office station and the remote stations.
Preferably, the process of preliminarily dividing the remote sites into different initial site groups in step S1 is as follows:
s11, setting a distance division threshold epsilon, and determining the physical distance between any one remote station and other remote stations in the remote stations;
and S12, preliminarily dividing the remote sites of which the physical distances to other remote sites do not exceed epsilon into different initial site groups by taking the distance division threshold epsilon as a reference to obtain different initial site groups.
Here, the physical distance is used as a threshold standard, and the remote sites are macroscopically divided in a group form, so that the distributed, wide-range and remote sites with remote positions can be managed comprehensively.
Preferably, when the remote stations in the same initial station group are further screened in step S2, the remote stations in the same initial station group send messages to each other:
if the message receiving interfaces of the remote stations in the same initial station group can receive messages sent by other remote stations except the remote stations, the remote stations which receive the messages sent by other remote stations except the remote stations belong to the same final station group; if the message receiving interface of the remote station in the same initial station group can not receive the message sent by any other remote station except the remote station, the remote station is an isolated remote station and is reserved independently;
if the message receiving interface of the remote station in the same initial station group can receive the messages sent by other remote stations except the remote station, the remote station which receives the messages sent by other remote stations except the remote station is reserved, and the following processing is carried out:

finally, the same initial site group may be divided into several final site groups and/or several isolated remote sites.
On the premise of dividing the macroscopic physical distance angle, the attribution relation of the remote sites is further refined on the basis of message transmission, and for a certain remote site, if messages sent by other remote sites except the remote site can be received during division and screening, it is indicated that no problem exists in communication with other remote sites, the remote sites are classified into the same final site group, and the subsequent overall management is facilitated; the remote stations which can absolutely not receive the messages sent by the remote stations except the remote stations are isolated, if the remote stations are forced to be grouped into the same final station group with other remote stations, the response or transmission of the messages is adversely affected in the subsequent overall management, and the reliability of power dispatching cannot be guaranteed; for the far-end stations which are further reserved and are screened in a message mutual sending mode, on the premise of dividing the macroscopic physical distance angle, a final station group is divided again, namely the same initial station group is possibly divided into a plurality of final station groups only, a plurality of final station groups and a plurality of isolated far-end stations, and the far-end stations are also possibly divided into the isolated far-end stations completely due to the improper basis of the macroscopic physical distance.

Here, as the remote station in the final site group, it is certain that the remote station can receive the messages sent by other remote stations except for the remote station itself, but considering the transmission delay between the stations, in order to take account of the quality of communication, the remote station with the highest response speed is selected as the main remote station in the final site group.
Preferably, in step S4, the process of respectively confirming the link status between the master remote station and the central station monitoring platform in each final station group and between the master remote station and the slave remote station in each final station group in the form of a scheduling number assignment response is as follows:
s41, the main remote station of each final station group requests the central station of the local side to establish TCP connection, the central station of the local side and the main remote station perform identification and confirmation, and the two stations establish TCP connection after the identification and confirmation;
s42, the central local station sends a scheduling signal packet to the main remote station of each final station group, after receiving the scheduling signal packet, the main remote station of each final station group feeds back a response packet to the central local station, and simultaneously forwards the scheduling signal packet to the slave remote station of the final station group where the central local station is located, and each slave remote station feeds back the response packet to the main remote station of the final station group where the slave remote station is located;
s43, if the central office end station receives the response packets fed back by all the main remote end stations, the link condition between the main remote end station and the central office end station monitoring platform in each final station group is normal; otherwise, the central station monitoring platform reminds the staff to confirm and repair the link condition between the central station and the main remote station which does not receive the response packet until the main remote station feeds back the response packet to the central station to be normal;
s44, if the main remote station of the final station group where each slave remote station is located receives the response packet fed back by each slave remote station, the link condition between each slave remote station and the main remote station of the final station group where the slave remote station is located is normal; otherwise, the master remote station feeds back the slave remote station message which does not receive the response packet to the central office station monitoring platform, and the central office station monitoring platform reminds the staff to confirm the link condition between the master remote station and the slave remote station which does not receive the response packet until the slave remote station feeds back the response packet to the master remote station normally.
Here, the link condition is firstly determined, and if the link condition is normal, it means that the transmission channel has higher reliability when each remote site feeds back the operating state to the central office site monitoring platform, and on the premise of realizing the overall management of the remote sites, a guarantee is provided for finally realizing the online monitoring of the operating state of the remote sites.
Preferably, when the remote sites in the same initial site group are further screened in step S2, if a plurality of isolated remote sites exist after the same initial site group is divided, link conditions between each isolated remote site and the central site monitoring platform of the central site are respectively confirmed in a form of scheduling number-discharge response, and when the link conditions are normal, interconnection is established between each isolated remote site and the central site monitoring platform of the central site.
Preferably, in step S5, each master remote site transmits the remote site topological connection data in the final site group to the central site monitoring platform, the central site monitoring platform receives the end site topological connection data, and the physical position data of the remote site collected by the GPS locator is matched with the GIS electronic map to visualize the topological connection data of each remote site; meanwhile, the central station monitoring platform of the local side matches the physical position data of the isolated remote station with a GIS electronic map, and images the position data of the isolated remote station.
Preferably, the terminal access device of each remote station comprises an active terminal access device and a passive terminal access device, and the operation indexes of the active terminal access device comprise a CPU utilization rate, a memory utilization rate and a device response time; the operation indexes of the passive terminal access equipment comprise voltage, current and power;

Example 1
In order to solve the problem that in power scheduling, remote sites are difficult to monitor online and manage in a centralized manner due to dispersion, wide range and remote locations, in this embodiment, a remote site topology online status monitoring method for power scheduling is provided, and a flowchart of the method refers to fig. 1, as shown in fig. 1, the method includes the following steps:
s1, preliminarily dividing remote sites into different initial site groups;
s2, further screening remote stations in the same initial station group to obtain a final station group;
s3, selecting a main remote station from the final station group, taking a remote station except the main remote station as a slave remote station, connecting the main remote station with a central office station, and connecting the main remote station with the slave remote station in each final station group;
s4, respectively confirming the link conditions between the main remote station and the central station monitoring platform of the local side in each final station group and between the main remote station and the slave remote station in each final station group in a dispatching and number-releasing response mode;
s5, each main remote station transmits topological connection data of remote stations in a final station group to a local central station monitoring platform, and the local central station monitoring platform images the topological connection data of each remote station to form a topological connection mapping image;
s6, determining normal operation indexes of each remote station and terminal access equipment thereof, endowing each operation index of each imaged remote station and terminal access equipment thereof with a reference standard, and setting a reference threshold error of each index;
s7, setting the central station of the local end, the remote station and the terminal access equipment of the remote station to start to operate, packaging the self operation log by the slave remote station of each final station group and transmitting the self operation log to the master remote station, packaging the self operation log by the master remote station and transmitting the self operation log and the operation log transmitted by each slave remote station to the monitoring platform of the central station of the local end;
s8, the central local station monitoring platform receives and analyzes the packed operation logs, compares each operation index in the operation logs of each remote station with a reference standard, and judges whether the distance between each operation index and the reference standard does not exceed the reference threshold error of each index, if so, the remote station is in a normal operation state; otherwise, an abnormal operation site exists, and the index with the distance from the reference standard exceeding the error of the reference threshold value of the corresponding index and the corresponding remote site are screened out from the topological connection mapping image and serve as the abnormal site.
Based on the technical processes of the steps S1 to S8, firstly, disassembling all remote stations in a group form on the whole, then, further, carrying out detailed screening on the remote stations of the group, dividing final station groups, selecting a main remote station from the final station groups to be connected with a local central station, and connecting the main remote station with a slave remote station in each final station group, namely, using the main remote station as a relay, so that the communication pressure of the local central station directly connected with each remote station is reduced, and the communication reliability is improved; then, link status between the master remote station and the central office station and link status between the master remote station and the slave remote station in each final station group are confirmed, and two levels are divided: firstly transmitting topological connection data of remote stations to form a topological connection mapping image, secondly, after determining standard operation indexes of each remote station and terminal access equipment thereof, packaging and transmitting self operation logs to a local central station monitoring platform by the remote stations, analyzing and comparing the local central station monitoring platform, screening out indexes with the distance from a reference standard exceeding a corresponding index reference threshold error and the corresponding remote stations from the topological connection mapping image as abnormal stations, and carrying out online monitoring on the operation state of the remote stations on the premise of realizing overall management of the remote stations.
In this embodiment, when the group is used to disassemble all the remote sites, the macro physical distance is firstly used as the threshold standard, and the physical distance is used as the group to divide the remote sites macroscopically, so that the remote sites that are dispersed, have a wide range and are far away from each other are conveniently managed in a comprehensive manner, specifically, in step S1, the process of preliminarily dividing the remote sites into different initial site groups is shown in a flowchart shown in fig. 2, and the process is as follows:
s11, setting a distance division threshold epsilon, and determining the physical distance between any one remote station and other remote stations in the remote stations;
and S12, preliminarily dividing the remote stations with the physical distance not exceeding epsilon with other remote stations into different same initial station groups by taking the distance division threshold epsilon as a reference to obtain different initial station groups.
Then, on the premise of dividing the macroscopic physical distance angle, the attribution relation of the remote site is further refined on the basis of message transmission. If the message receiving interfaces of the remote stations in the same initial station group can receive messages sent by other remote stations except the remote stations, the remote stations which receive the messages sent by other remote stations except the remote stations belong to the same final station group; if the message receiving interface of the remote station in the same initial station group can not receive the message sent by any other remote station except the remote station, the remote station is an isolated remote station and is reserved independently;
if the message receiving interface of the remote station in the same initial station group can receive the messages sent by other remote stations except the remote station, the remote station which receives the messages sent by other remote stations except the remote station is reserved, and the following processing is carried out:
for the mutual message transmission between any one of the reserved remote sites and other remote sites except the remote site, if the message receiving interface can receive the messages transmitted by other remote sites except the remote site, the remote sites which receive the messages transmitted by other remote sites except the remote site belong to the same final site group; if the message receiving interface can not receive the messages sent by other remote sites except the remote site or can only receive the messages sent by other remote sites except the remote site, the remote site is an isolated remote site and is reserved independently;
finally, the same initial site group may be divided into several final site groups and/or several isolated remote sites.
On the whole, for a certain remote site, if the messages sent by other remote sites except the remote site can be received during division and screening, the communication between the remote site and other remote sites is not problematic, and the remote sites are classified into the same final site group, so that the subsequent overall management is facilitated; the remote sites which can absolutely not receive the messages sent by the remote sites except the remote sites are isolated, if the remote sites and other remote sites are forcibly grouped into the same final site group, the response or transmission of the messages is adversely affected in the subsequent overall management, and the reliability of power dispatching cannot be guaranteed; for the far-end stations which are further reserved and are screened in the form of mutual message sending, on the premise of dividing the macro physical distance angle, a final station group is divided again, that is, the same initial station group may be divided into only a plurality of final station groups, a plurality of final station groups and a plurality of isolated far-end stations, and all the far-end stations are divided into the isolated far-end stations due to the improper basis of the macro physical distance.
After the attribution relationship of the remote stations is further refined, the relationship between the master station and the slave station is screened and divided from the perspective of communication pressure, if a certain remote station is taken as a 'master' station, the certain remote station must have the performance required to be taken as a 'relay', the response speed is high firstly, and for the remote stations divided into a certain final station group, the condition that messages sent by other remote stations except the self can be received is met, but in consideration of the transmission delay among the stations, in order to take the communication quality into consideration, the remote station with the highest response speed is selected as the master remote station in the final station group. Therefore, in this embodiment, when the main remote site is selected from the final site group, the remote sites in the same final site group send messages to each other, the message receiving interface of each remote site receives and responds to the messages sent by other remote sites except the remote site itself, and the remote site with the highest response speed is selected as the main remote site in the final site group.
After the attribution relation of the remote sites is refined, if the purpose of monitoring the online running state of the remote sites is finally achieved, the link serves as a link for information transmission between the central office station and the remote sites, the quality condition of the link must be clear, if the link is normal, the fact that a transmission channel has high reliability when each remote site feeds back the running state to the central office station monitoring platform means that the remote sites can finally achieve online monitoring of the running state of the remote sites on the premise that overall management of the remote sites is achieved.
