Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The feeder operation management method provided by the application can be applied to the application environment shown in fig. 1. Wherein the data collection server 102 communicates with the feeder management server 104 over a network. The data collection server 102 is configured to collect feeder operation data generated during feeder operation, and send the feeder operation data to the feeder management server 104 for management and analysis. The management terminal data acquisition server 104 acquires feeder line operation data; obtaining a main supply line analysis result and a standby supply line analysis result corresponding to the feeder line operation data through an N-1 analysis method; determining a feeder line adjusting scheme corresponding to the feeder line operation data according to the analysis result of the main supply line and the analysis result of the standby supply line; and feeding back a feeder line adjustment scheme. The data collection server 102 and the feeder management server 104 may be implemented by independent servers or a server cluster formed by a plurality of servers, or may be cloud servers.
In one embodiment, as shown in fig. 2, a feeder operation management method is provided, which is described by taking the feeder management server 104 in fig. 1 as an example, and includes the following steps:
step 201, obtaining feeder line operation data.
The feeder operation data is various data generated in the operation process of the feeder, and includes related data of a main supply line and related data of each standby supply line in the feeder. For example, the feeder line corresponds to the coincidence data, the current data and the like, the feeder line operation analysis can be carried out based on the data, and the abnormal operation conditions of the feeder line, such as heavy overload operation, low load operation and the like, with uneven load distribution can be identified. The feeder operation management method of the application may specifically perform feeder operation management based on feeder operation data of a certain time period, where the obtained feeder operation data is operation data in a fixed time period.
Specifically, the feeder operation management method is specifically used for ensuring that a feeder operation mode is in a normal state so as to ensure safe and economic operation of a power grid. The feeder line fault tripping power failure event can be effectively reduced through the operation management of the feeder line, the power failure time of customers is reduced, and the satisfaction degree of the customers using power is improved. Before the feeder operation management is performed, analysis needs to be performed according to current feeder operation data to determine that a corresponding feeder is abnormal, and corresponding adjustment is performed.
And 203, acquiring a main supply line analysis result and a standby supply line analysis result corresponding to the feeder line operation data through an N-1 analysis method.
The N-1 analysis method is used for analyzing the feeder operation process based on an N-1 principle, wherein the N-1 principle is also called a single failure safety inspection rule and is a technical requirement from the perspective of safe operation of a power grid. Power system design regulations dictate that network designs must meet certain safe operating requirements. The relatively common network safety operation requirement is that the test is met, that is, after one of all lines is arbitrarily disconnected, each operation index of the system can still meet the given requirement. In the initial stage of forming a network structure in network planning, the most important principle is that overload does not occur on a network, that is, the network can meet the requirement of safe power transmission, and therefore, overload verification after line-by-line disconnection is required. When any line is disconnected, overload can be caused to other lines of the system or the system is disconnected, and the network does not meet the N-1 test. In this case, some grid planning method must be applied for network expansion until the N-1 test is satisfied. In fact, in power grid planning, the N-1 test principle is a technical criterion for evaluating planning schemes formed by various planning methods, and is also a simple planning method. The inspection principle is often used in conjunction with heuristic methods, and if the influence of economic factors is not considered, any planning scheme can pass the N-1 inspection, i.e. it can be proved that it has certain technical feasibility.
Specifically, in the scheme of the application, the obtained feeder line operation data can be analyzed through an N-1 analysis method to obtain a corresponding analysis result. The analysis result specifically comprises the analysis result of the main supply line and the analysis result of the standby supply line. In one embodiment, in the analysis result, the main supply line or the standby supply line with the abnormality can be labeled correspondingly, and the labeling mainly includes possible reasons for feeder line operation errors.
And step 205, determining a feeder line adjustment scheme corresponding to the feeder line operation data according to the analysis result of the main supply line and the analysis result of the standby supply line.
The feeder line adjustment scheme refers to a corresponding reference scheme for governing problems found in the feeder line operation process, for example, for an overload feeder line load problem, a corresponding feeder line conformity adjustment scheme can be given according to a feeder line load reason determined in a line analysis result. The feeder operation and maintenance personnel of the power grid can perform corresponding feeder adjustment based on the feeder adjustment scheme.
Specifically, after the feeder management server 104 determines the analysis result of the main supply line and the analysis result of the auxiliary supply line, for the feeder line in which an abnormality occurs, a corresponding adjustment suggestion may be given according to the analysis result of the main supply line and the analysis result of the auxiliary supply line.
And step 207, feeding back a feeder line adjustment scheme.
Specifically, after the feeder line anomaly analysis is performed and the corresponding analysis result is obtained, the corresponding main supply line analysis result and the standby supply line analysis result may be fed back to the feeder line operation and maintenance personnel.
The feeder operation management method comprises the steps of obtaining feeder operation data; obtaining a main supply line analysis result and a standby supply line analysis result corresponding to the feeder line operation data through an N-1 analysis method; determining a feeder line adjusting scheme corresponding to the feeder line operation data according to the analysis result of the main supply line and the analysis result of the standby supply line; and feeding back a feeder line adjustment scheme. The feeder abnormal operation mode analysis function is provided, the abnormal operation state of the feeder is found based on the feeder operation data, a corresponding adjustment scheme is provided, the abnormal operation mode of the feeder is found in time, efficient and accurate feeder operation management is carried out, and safe operation of a power grid is guaranteed.
In one embodiment, as shown in FIG. 3, step 203 comprises:
and acquiring the main supply maximum load current corresponding to the feeder line operation data.
And when the main supply maximum load current is smaller than a first preset current threshold, obtaining the standby supply maximum load current corresponding to the feeder line operation data.
When the maximum load current of the backup power supply is smaller than a first preset current threshold value, the main power supply circuit is judged to normally operate, and when the maximum load current of the backup power supply is larger than or equal to the first preset current threshold value, the main power supply circuit is judged to abnormally operate.
The main supply maximum load current is a maximum current value of a time point corresponding to a maximum load in a preset time period of a main supply line of the feeder group, and the standby supply maximum load current is a maximum current value of a time point corresponding to the maximum load in a preset time period of each standby supply line. The first preset current threshold may be set according to the current main supply and secondary supply maximum load currents in the historical data, where the power grid actually operates normally. In a specific embodiment, the current value of the main supply line is generally greater than or equal to 50A and the current value of the auxiliary supply line is less than 50A in the feeder group in the standard wiring mode summarized by historical experience. The first preset current threshold may be set to 50A.
Specifically, when a main supply line analysis result corresponding to feeder line operation data is determined through N-1 analysis, it can be determined based on historical empirical data that a maximum load current of a main supply line in the feeder line is generally larger than a certain first preset current threshold, and a maximum load current of an auxiliary supply line is generally smaller than the first preset current threshold, at this time, it can be seen that the main supply maximum load current is smaller than the first preset current threshold based on the N-1 analysis, and when the main supply maximum load current is smaller than the first preset current threshold, the auxiliary supply maximum load current corresponding to the feeder line operation data is obtained. If the maximum load current of the standby power supply is smaller than the first preset current threshold, the possible overall power supply in the current time is considered to be low, and the main power supply circuit is judged to operate normally. When the standby power supply circuit with the maximum load current greater than or equal to the first preset current threshold exists, the current of the main power supply circuit is surpassed by the standby power supply circuit, and the condition that the main power supply circuit is abnormal in operation can be judged. According to the method and the device, the abnormity analysis of the main supply line is carried out through the main supply line and the maximum load current of the standby supply line, the abnormal line can be effectively found out, and the effectiveness of feeder line management is guaranteed.
In one embodiment, step 203 further comprises: obtaining the standby maximum load current corresponding to the feeder line operation data; and when the maximum load current of the backup power supply is greater than or equal to a first preset current threshold, judging that the backup power supply circuit is abnormal in operation.
The standby supply maximum load current refers to a maximum current value of a time point corresponding to the maximum load in a preset time period of each standby supply line. Specifically, when the backup lines are analyzed, the analysis and evaluation may be performed based on the maximum load currents corresponding to all the backup lines. Specifically, when the analysis result of the backup power supply line corresponding to the feeder operation data is determined through N-1 analysis, since it can be determined based on historical empirical data that the maximum load current of the backup power supply line is generally smaller than the first preset current threshold, it can be directly seen whether the maximum load current corresponding to each backup power supply line flows greater than or equal to the first preset current threshold based on N-1 analysis, if so, the maximum load current corresponding to each backup power supply line is greater than or equal to the first preset current threshold. This indicates that the current backup power supply line has an excessive current and an abnormal power supply line. The method and the device for analyzing the abnormal state of the backup power supply circuit carry out the abnormal analysis of the backup power supply circuit through the maximum load current of the backup power supply circuit, can effectively find out the abnormal circuit, and guarantee the effectiveness of feeder line management.
In one embodiment, before feeding back the feeder line adjustment scheme, the method further includes: acquiring the number of terminal users and the number of terminal nodes corresponding to feeder line operation data; and determining a terminal adjustment scheme corresponding to the feeder line operation data according to the number of the terminal users and the number of the terminal nodes. Step 207 comprises: and feeding back a feeder line adjusting scheme and a terminal adjusting scheme.
The Feeder Terminal device is called FTU (Feeder Terminal Unit) for short, and is installed on a Feeder line, monitors a column switch, completes the functions of remote measurement, remote control, remote signaling and fault detection, communicates with a distribution automation main station, provides the running condition of a distribution system and various parameters, namely information required by monitoring and controlling, including on-off state, electric energy parameters, phase-to-phase faults, grounding faults and parameters during faults, executes commands issued by the distribution main station, adjusts and controls distribution equipment, and realizes the functions of fault location, fault isolation and quick recovery of power supply in a non-fault area. The FTU is an intelligent terminal device installed on a distribution room or feeder. The intelligent power distribution system can communicate with a remote power distribution substation, sends the operation data of the power distribution equipment to the power distribution substation, and can also receive the control command of the power distribution substation to control and regulate the power distribution equipment. Specifically, when the feeder operation management is performed, the number of users and the number of terminal nodes corresponding to one feeder should be within a certain number range, and when the number of terminal users or the number of terminal nodes is abnormal, it may also be determined that the feeder operates abnormally, and at this time, corresponding feeder line adjustment may be performed to ensure that the feeder operates normally. According to the method and the device, the abnormity analysis of the backup supply line is carried out through the number of the terminal users and the number of the terminal nodes, the abnormal line can be effectively found out, and the effectiveness of feeder line management is guaranteed.
In one embodiment, after determining the feeder line adjustment scheme corresponding to the feeder line operation data according to the analysis result of the main supply line and the analysis result of the backup supply line, the method further includes:
and 302, generating feeder line alarm information according to the analysis result of the main supply line and the analysis result of the standby supply line.
And step 304, feeding back feeder line alarm information.
The feeder line alarm information is used for alarming operation and maintenance personnel. Specifically, when the main supply line analysis result or the backup supply line analysis result analyzes and determines that an abnormal main supply line or a abnormal backup supply line of the feeder line exists, corresponding feeder line warning information can be generated according to the reason of the abnormality and the corresponding specific line, and then a system message or a short message and the like inform a feeder line operation and maintenance worker of paying attention so that the feeder line operation and maintenance worker can determine whether to adjust the feeder line and how to adjust the feeder line according to a feeder line adjustment scheme fed back by the system in time. By feeding back the feeder line alarm information, the prompt of reminding can be effectively improved.
In one embodiment, obtaining feeder operational data comprises: and when the preset management period node is reached, obtaining feeder line operation data.
The preset management period node refers to a fixed time node in a management period, specifically, the feeder operation management method of the present application may perform feeder operation management in a timed manner, and the management period and the preset management period node may be set by operation and maintenance personnel according to actual conditions. Therefore, the abnormal condition of the feeder line operation mode can be automatically analyzed according to the analysis algorithm of the feeder line abnormal operation mode under the time frequency predefined by the system, so as to alarm in time. In another embodiment, the system may be specifically configured to "automatically trigger analysis after the feeder operation mode is adjusted" to implement the feeder operation mode analysis triggered by the service work order. When the operation and maintenance operation involves activities such as distribution network operation mode adjustment, comprehensive power failure and the like, the operation mode of the feeder line involved is analyzed by the operation mode conversion work order and the power failure application work order triggering system. In another embodiment, the system may be specifically configured to "manually initiate and analyze all feeder operation modes in a certain area by a user" or "manually initiate and analyze a single feeder operation mode by a user", and an operation and maintenance person manually specifies a feeder range and then triggers the feeder operation mode analysis as needed. In this embodiment, feeder operation management can be performed in time through periodic triggering, so that timeliness of feeder operation management is ensured. In addition, diversified feeder operation management can be realized by 'automatically triggering and analyzing after the feeder operation mode is adjusted' or 'manually initiating and analyzing all feeder operation modes in a certain area by a user'.
