It is a process of promoting by the test main station commanding multiple test instruments. Any problem in the cooperative process between the test main station and the test instrument may lead to the failure of the FA test, which greatly reduces the reliability of the FA test. However, the existing FA test method does not study the cooperative promotion means of the test main station and the test instrument, and the reliability of the FA test is not high. SUMMARY

[0050] Embodiment one

[0051] Please refer to FIG. 1, which is a flowchart of a feeder automation test method provided by an embodiment of the present application, including the following specific steps:

[0052] S1, calculating the voltage effective value and the current effective value of each node in the power distribution network framework under different fault handling section conditions of the feeder automation system;

[0053] Preferably, before calculating the voltage effective value and the current effective value of each node in the power distribution network framework under different fault handling section conditions of the feeder automation system, it further includes: applying to the RTI runtime support environment for registration of a corresponding electrical quantity injection time window, until a time window registration success notification returned by the RTI is received; after receiving the time window registration success notification, starting to perform feeder automation test, applying to the RTI runtime support environment for a runtime window, so that the time window of the RTI runtime support environment starts to run.

[0054] In view of the problems existing in the prior art, the application proposes a collaborative promotion means for FA testing based on a high-level architecture (HLA) and an agent (Agent) to improve the reliability of FA testing and realize orderly and collaborative promotion of the dynamic process of FA testing.

[0055] The application first establishes an HLA / Agent-based FA testing framework based on the principles of HLA and Agent; then, based on the HLA time management service, analyzes a time management strategy and a message passing mechanism suitable for the collaborative promotion of FA testing, and in combination with a test master station electrical quantity injection time window, proposes an FA testing collaborative promotion strategy. It should be noted that the test master station electrical quantity injection time window is a key problem of FA testing, and is the brain commanding the orderly promotion of FA testing according to each section. The time constraint passed by each node is the key to the success or failure of FA testing. Please refer to FIG. 2 for a schematic diagram of the test master station electrical quantity injection time window.

[0056] I. FA field test system framework

[0057] The FA field test system framework mainly consists of a test master station, a communication network, a test instrument, a virtual relay protection device, a virtual power distribution terminal and a field power distribution terminal. Please refer to FIG. 3 for a diagram of the FA test system framework.

[0058] In FIG. 3, the test master station is the command center of FA testing and should at least have: (1) a 10kV primary equipment power distribution network framework to be built, with the ability of power distribution network power flow calculation and short-circuit calculation, to generate voltage and current electrical quantity effective values of each time sequence of FA; (2) the test master station sends the electrical quantity effective values of each node of the framework to the test instrument, and receives the simulated circuit breaker position information of the test instrument; (3) a virtual power distribution terminal module with "three remote" and FA functions of the physical power distribution terminal; (4) a virtual protection device module with at least current protection I~II, zero sequence current protection and reclosing functions. The test instrument should have the function of receiving the electrical quantity effective value information of the test master station and converting it into continuous analog waveform to inject into the field power distribution terminal.

[0059] II. HLA / Agent principles

[0060] HLA is a general high-level architecture in the field of modeling and simulation, which consists of a simulation federation and a plurality of federation members. The simulation federation refers to a hybrid simulation system composed of multiple different simulation platforms, and the federation member refers to a simulation program running in the simulation federation. The interface standard of HLA is realized by RTI, which defines time management services including time management strategies and message passing mechanisms to ensure the correctness of the collaborative promotion among the federation members. Please refer to FIG. 4 for a basic structure diagram of HLA.

[0061] Agent is an intelligent entity that can perceive the environment and act on it, with autonomy, reactivity, and interactivity. The basic idea is to divide the research object into multiple Agents according to different functions, each Agent contains specific functions, by studying the specific functions of individual system, and then obtaining the macro behavior of the system, which can clearly reflect the coupling relationship between the functions of the FA test elements, and improve the efficiency of the cooperation between the modules in the test master station and the test instrument. Please refer to Figure 5 for the basic structure of Agent.

[0062] The main structure of Agent can be divided into three types: reactive, deliberative and hybrid. Reactive Agent can quickly respond when the conditions set by itself are met, with fast response speed, but without reasoning ability; deliberative Agent can reason and respond according to external models, so its response speed is slower. Hybrid Agent integrates the advantages of the first two, it can both reason and respond quickly. The choice of Agent main structure should be based on the functional requirements of the device or software. For example, the simulation Agent of the test master station needs to perform power flow calculation or short circuit calculation on the voltage and current at each circuit breaker, load switch and sectionalizing switch node in the distribution network, involving the calculation and reasoning of its own data, so it is appropriate to use a deliberative structure; while for the analog output interface Agent of the test instrument, since it only receives voltage and current analog waveform data and forwards them, there is no reasoning process, so a reactive structure can be used.

[0063] III. FA test collaborative promotion framework

[0064] Please refer to Figure 6 for the overall architecture of the FA test system based on HLA / Agent, which is composed of test master station federation members, test instrument federation members and field distribution terminal. Each federation member is composed of multiple Agents, and the information exchange between the test master station and the test instrument is realized under the optical fiber or wireless communication wide area network, and the collaborative promotion of each element of FA test is realized under the support of RTI interface, to achieve the established FA test goal.

[0065] The test master station federation member includes:

[0066] (1) Simulation Agent: with power flow calculation and short circuit calculation functions for distribution network, responsible for generating the effective value of voltage and current at each node of the distribution network; with distribution network topology change function, receiving analog circuit breaker position change information and changing the distribution network topology; with FA logic correctness determination function, mainly responsible for determining the switch action information fed back from the field distribution terminal to the master station, if it meets the established FA logic, the topology will be changed and the next test will continue, otherwise the test will be stopped.

[0067] (2) Virtual relay protection Agent: with functions of current protection I~II, zero sequence current protection and secondary reclosing; Virtual distribution terminal Agent: with functions of "three remote" and FA of physical distribution terminal.

[0068] (3) FA test time sequence section control Agent: according to FA test flow, it is divided into multiple FA test time sequence sections, and FA test is carried out according to the time sequence section.

[0069] (4) RTI interface and RTI runtime support environment: according to the time management service of RTI runtime support environment, it is orderly promoted according to the established time window of FA test master station electrical quantity injection.

[0070] Test instrument federation members include:

[0071] (1) Waveform generation Agent: responsible for receiving test master station voltage and current effective value information, and generating continuous voltage and current analog waveform.

[0072] (2) Analog circuit breaker Agent: responsible for receiving switch quantity information of field distribution terminal, and simulating field switch action as an analog circuit breaker.

[0073] (3) Interface Agent: on the one hand, it continuously outputs waveform to the distribution terminal, and on the other hand, it receives switch quantity of the distribution terminal. Communication between Agents is realized by KQML to support cooperative work between simulation entity Agents. KQML message follows the following syntax format:

[0074] (ask-all / / operation name;

[0075] :sender Agent sending the message;

[0076] :receiver Agent receiving the message;

[0077] :content specific content of the message expressed by the communication primitive;

[0078] :language name of the language used in the content parameter field;

[0079] :ontology name of the term definition set in the content parameter field)

[0080] The time management service of RTI runtime support environment is the key to realize the cooperative promotion of FA test. Therefore, first, the test master station and test instrument are connected to the RTI runtime support environment through the RTI interface. Please refer to FIG. 7 for a schematic diagram of various RTI interface functions.

[0081] Four, FA test cooperative promotion strategy based on HLA

[0082] 4.1 Time management strategy

[0083] In the voltage time type FA test, the effective value injection time window of the electrical quantity of the test master station, the network delay between the test master station and the tester, the processing time of each element, the closing time limit (X time limit) with pressure on one side, the locking time limit (Y time limit), the reclosing time and other time factors are the key to the success of the FA test promotion. Therefore, the time management service in HLA is introduced to ensure the cooperation and promotion of each element in the FA test. Time management mainly includes three aspects of time management strategy of federal members, message passing mechanism and logical time promotion.

[0084] The time management strategy of federal members in HLA describes the relationship between the logical time promotion of federal members and other federal members, which is divided into time control and time limited, as shown in the following table 1.

[0085] Table 1 Time management strategy type and meaning

[0086] In the process of FA test promotion, the test master station injects voltage and current electrical quantity to each tester according to the electrical quantity injection time window, which affects the operation of each tester. However, the test master station is not affected by the tester federal member due to the control of the test master station time window, so the test master station federal member adopts only "time control" mode; The tester needs to receive the voltage and current effective value of the test master station to generate continuous analog quantity waveform output to the field distribution terminal, so the tester is affected by the voltage and current effective value injection of the test master station. However, the test master station has set the injection point of electrical quantity, so the processing time of the tester does not affect the time promotion of the test master station, and the tester is "time limited".

[0087] 4.2 Message passing mechanism

[0088] The message passing mechanism of HLA includes two aspects: one is the message transmission mode; The second is the message passing sequence. Among them, the message transmission mode is divided into "reliable" and "best effort" two kinds, the former adopts TCP / IP protocol, has retransmission mechanism, that is, when a message passing fails, it will be transmitted again, which can effectively guarantee the reliability of information transmission, but usually needs to increase the transmission delay. The latter adopts UDP / IP protocol, does not have retransmission mechanism, so its transmission reliability is poor, but can effectively reduce the transmission delay. The time window constraint condition of the effective value injection of electrical quantity in the process of FA test involves high time delay requirement, and for reliability, the reliability of information transmission can be improved by setting messages and heartbeats in the test master station, so the "best effort" mode is more suitable.

[0089] HLA supports two message passing orders: receiving order (RO) and time stamp order (TSO). RO is the way with minimum delay, RTI creates a queue for each federation member and passes messages to the member in FIFO order. This way is used in the case where the requirement for transmission delay is higher than the requirement for causality; TSO is the way to guarantee message causality, RTI will ensure that all messages delivered to the member are in time stamp order, i.e. the received messages are stored in the queue until it is confirmed that there is no smaller time stamp message to arrive, and then these messages are forwarded to the member.

[0090] If the system requires causality higher than the delay requirement, TSO is used for transmission to ensure the correctness of the causality logic in the system; if the system requires delay higher than the causality requirement, RO is used for transmission to improve transmission speed. There are many time factors involved in the FA test process, such as one side of the pressure delay closing time limit (X time limit), lockout determination time limit (Y time limit), residual voltage lockout discrimination time limit (Z time limit), contact switch delay closing time limit (XL time limit) and reclosing time limit. As long as the electrical quantity injection time window constraint condition proposed in this paper is met, the orderly progress of FA test can be guaranteed, therefore, the "RO" way with the smallest delay is needed to be used to better adapt to the FA test master electrical quantity effective value injection time window and ensure the orderly collaborative progress of FA test.

[0091] 4.3 FA test collaborative progress strategy based on HLA

[0092] Please refer to Figure 8 for the FA test collaborative progress strategy based on HLA. First, the pre-test preparation work is carried out, the test master and test instrument federation members apply for registration of electrical quantity effective value injection time window to RTI runtime support environment through registerFederationSynchronizationPoint() function, and RTI will return synchronizationPointRegistrationSuceeded() function to inform each federation member of the success of time window registration. Then the FA test can be started, the test master applies for runtime window to RTI runtime support environment through nextEventRequest() function, after the runtime window starts, when a certain injection point is reached, RTI runtime support environment sends timeAdvanceGrant() function to inform the test master federation member to allow injection, the test master starts effective value injection immediately, and so on, until the FA test is completed.

[0093] 4.4 FA test collaborative progress process based on HLA

[0094] During the FA test process, due to the influence of continuous and discrete events such as test master station voltage and current electrical quantity injection, optical fiber or wireless communication network delay, test instrument processing, power distribution terminal processing, protection device processing, and important time factors such as one-side voltage delay closing time limit (X time limit) and locking determination time limit (Y time limit) existing in the test process, it may cause the FA test to advance incorrectly, and even fail. Therefore, based on the powerful time advance function of HLA, combined with the effective value injection time window of the test master station electrical quantity, the orderly advancement of the FA test is ensured. Please refer to FIG. 9 for the specific advancement process diagram of the FA test.

[0095] The advancement process is as follows:

[0096] (1) The test master station applies for registration of the electrical quantity injection time window to the RTI runtime support environment, and the RTI informs the test master station that the time window registration is successful. The FA test starts, and the test master station applies for a runtime window to the RTI runtime support environment. The time window starts running.

[0097] (2) The test master station builds a measured power distribution network framework. Through power flow calculation and short-circuit calculation, the voltage effective value and current effective value of each node in the power distribution network framework under different fault handling sections of the feeder automation system are obtained.

[0098] Specifically, the test master station includes a power distribution network simulation platform. The power distribution network framework can be built, and the fault can be set. Combined with the power flow calculation and short-circuit calculation theoretical formula algorithm, the voltage and current effective values of each node under different fault handling sections of the FA are automatically generated through the simulation platform.

[0099] S2, send the voltage effective value and current effective value to the corresponding test instrument, so that the corresponding test instrument converts the voltage effective value into an analog voltage waveform and the current effective value into an analog current waveform after receiving the voltage effective value and current effective value, outputs the analog voltage waveform and analog current waveform to the corresponding field power distribution terminal, and returns the switch displacement information of the field power distribution terminal;

[0100] Preferably, sending the voltage effective value and current effective value to the corresponding test instrument comprises: when the RTI runtime support environment detects that the time window reaches the injection point, sending the voltage effective value and current effective value to the corresponding test instrument.

[0101] Preferably, the analog voltage waveform and the analog current waveform are output to the corresponding field power distribution terminal, and the switch position information of the field power distribution terminal is returned, including: outputting the analog voltage waveform and the analog current waveform to the corresponding field power distribution terminal, so that the corresponding field power distribution terminal acts according to the analog voltage waveform and the analog current waveform to generate a corresponding switch quantity; generating corresponding switch position information according to the switch quantity of the field power distribution terminal, and returning the switch position information to the test master station.

[0102] (3) The test master station injects the voltage and current effective value data into the tester:

[0103] The RTI runtime support environment monitors the time window to reach the first injection point, and then informs the test master station to allow the first injection. The test master station injects the voltage effective value and the current effective value into the tester, the virtual relay protection device and the virtual power distribution terminal, respectively, with field and virtual network delays.

[0104] (4) After the tester receives the data, the effective value is converted into an analog voltage and current waveform, which is continuously output to the field power distribution terminal:

[0105] For the field: the tester converts the effective value data into continuous voltage and current analog waveforms: the voltage effective value is converted into an analog voltage waveform, and the current effective value is converted into an analog current waveform; for the virtual device: the waveforms are simulated and generated inside the virtual protection and virtual power distribution terminal. Specifically, the tester itself contains a function module that expands the voltage and current effective value into a waveform, which can accept the effective value of the test master station and automatically generate an analog waveform output to the power distribution terminal.

[0106] For the field: the tester continuously injects the voltage and current analog waveforms into the field power distribution terminal. For the virtual device: the waveforms are simulated and injected inside the virtual device.

[0107] (5) After the field power distribution terminal receives the analog voltage and current waveforms, if it needs to act, it will return the switch quantity to the tester simulation circuit breaker; the virtual device starts the protection principle judgment and the FA principle judgment, and if it acts, it will return the switch quantity to the simulation circuit breaker in the virtual device.

[0108] Specifically, if the fault setting value is exceeded, the power distribution terminal will act (open), otherwise, if the power distribution terminal is continuously powered and meets the FA logic, it will be closed (specifically refer to the FA logic). After acting, the power distribution terminal will generate a switch quantity and return it to the tester simulation circuit breaker. The returned switch quantity can be understood as a signal "1" or "0", for example, "1" represents the switch closed, and "0" represents the switch open.

[0109] (6) For the field: the tester acts as a simulated circuit breaker; for the virtual device: simulate the circuit breaker action inside the virtual device.

[0110] For the field: the tester simulates the circuit breaker to return the switch position information to the test master station, with field network delay; for the virtual device: the virtual device returns the switch position information to the test master station, with virtual network delay.

[0111] Specifically, the tester as a simulated circuit breaker accepts signal "1" and responds to signal "1" to act. After the simulated circuit breaker acts, "switch position information" is generated, which can also be understood as "1" and "0", for example, "1" is the closed state of the switch, and "0" is the open state of the switch, which is sent back to the test master station, and the test master station acts according to the switch position information to simulate the power distribution network topology.
