Abstract

The present invention discloses a method, system, storage and computing device for synchronously uploading power data. By classifying and analyzing the telemetry data forwarded from a substation to a master station, the telemetry data is divided into power telemetry, current telemetry and other telemetry according to the measurement type. The power telemetry includes active power telemetry and reactive power telemetry. Further, according to the association relationship between the power telemetry and the bus, the power telemetry and current telemetry are classified according to multiple bus telemetry. The system subscribes to the real-time value of the power telemetry. When the power telemetry changes, the active power and reactive power vector values of the time section are scanned, and the validity of their vector sum is judged according to logical conditions such as amplitude and quality. When the validity logic check passes or the system sending timeout time threshold is reached, the system sends the power telemetry of the current section to the master station. It solves the problem that the bus power data received by the master station is unbalanced due to reasons such as power grid load fluctuations, sampling performance differences between measurement and control devices, and communication performance differences.

Description

Technical Field

[0001] The present invention relates to a method, system, storage and computing device for synchronously uploading power data, belonging to the technical field of substation automation systems. Background Art

[0002] The monitoring of substation power by the dispatching master station is an important part of evaluating the operation of the power grid and the load situation, and plays a crucial role in power grid dispatching. However, due to reasons such as power grid load fluctuations, sampling performance differences between measurement and control devices, and communication performance differences, there is a certain time difference in the telemetry data upload between different measurement and control devices. By analyzing the operation of actual measurement and control devices in multiple substations, when multiple measurement and control devices collect data simultaneously, the time difference in data upload between measurement and control devices is mostly between 300 ms and 600 ms. If the power flow fluctuation speed of the substation is fast and the span is large, there is a high probability that the bus power vector value will exceed the limit at a certain moment. If the system uploads the power data of this time section to the master station at this time, it will cause the bus power data received by the master station to exceed the limit or be unbalanced.

[0003] In domestic substations, after years of digital construction, high-performance gateway devices have basically been configured, with abundant data access, storage, computing and forwarding capabilities. They collect data from all substation equipment, including measurement and control devices, and perform real-time processing, and have the ability to perform data analysis from the perspective of the entire substation. The communication between the substation and the master station uses a gateway device, and most of the communication uses the IEC60870-5-104 standard.

[0004] In view of the above analysis, the synchronization optimization of the uploaded data can be further carried out in the system, which solves the problem of unbalanced bus power data received by the master station due to reasons such as power grid load fluctuations, sampling performance differences between measurement and control devices, and communication performance differences.

[0015] According to the association relationship between the power telemetry points, current telemetry points and the bus, classify the power telemetry points and current telemetry points by bus.

[0016] Further, the telemetry points for which the system forwards telemetry data are divided into power telemetry points, current telemetry points, and other telemetry points, expressed as:

[0017] K = {W, A, O} where K: the set of all system-forwarded telemetry points, W: the set of power telemetry points, A: the set of current telemetry points, O: the set of other telemetry points.

[0018] Among them, the power telemetry point is a measurement model that describes the active power and reactive power characteristics of the interval connected to the bus in the substation.

[0019] In some embodiments, the classification of the power telemetry points and current telemetry points by bus includes:

[0040] The present invention will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0041] Embodiment 1

[0042] First, a method for synchronous upload of power data is provided, including:

[0043] Obtain real-time data of power remote measurement points; the types of power remote measurement points are divided into active power remote measurement points and reactive power remote measurement points;

[0044] In response to a change in the real-time data of a power remote measurement point, according to whether this power remote measurement point is an active power remote measurement point or a reactive power remote measurement point; perform a section scan on the real-time data of all active power remote measurement points or reactive power remote measurement points of the same type corresponding to the busbar to which this power remote measurement point belongs, obtain the real-time data of the section power remote measurement points, and calculate the vector sum of the real-time data of the section power remote measurement points;

[0045] Perform validity logic verification on the vector sum of the real-time data of the cross-section power remote measurement points and all the real-time data of the power remote measurement points participating in the vector calculation;

[0046] In response to passing the validity logic verification, send the real-time data of the cross-section power remote measurement points to the master station in the same data frame, and record the current moment as T h ;

[0047] In response to the validity logic verification failing and the absolute value of the time difference between the current moment T c and T h being greater than the preset timeout △t, send the real-time data of the cross-section power remote measurement points to the master station in the same data frame, and record the current moment T h ;

[0048] In response to the validity logic verification failing and the absolute value of the time difference between the current moment T c and T h being less than or equal to the timeout △t, no processing is performed.

[0049] In some embodiments, as Figure 1 shown, a method for synchronously uploading power data includes the following steps:

[0050] Step 1: Divide the system-forwarded telemetry data into power remote measurement points, current remote measurement points, and other remote measurement point sets, and classify the power remote measurement points and current remote measurement point sets according to the busbars;

[0051] Step 2: Receive the power telemetry values in real time by subscription and monitor the changes in the real-time power telemetry values;

[0052] Step 3: When the system receives the real-time change data of the power remote measurement points, perform a cross-section scan on all the real-time data of the active power remote measurement points or reactive power remote measurement points under the busbar to which the power remote measurement point belongs and calculate their vector sum;

[0053] Step 4: Perform validity logic verification on the vector sum of the real-time data of the cross-section active power remote measurement points or reactive power remote measurement points and the real-time data of the power remote measurement points participating in the vector calculation;

[0054] Step 5: When the validity logic verification passes, the system sends the real-time data of the scanned active power remote measurement points or reactive power remote measurement points to the master station in the same data frame, and records the current moment as T h ;

[0055] Step 6: When the validity logic verification fails, if the current moment T c and T hIf the absolute value of the time difference is greater than the timeout period Δt, the active power telemetry data or reactive power telemetry data scanned by the system will also be sent to the master station in the same data frame, and the current time T will be recorded. h Otherwise, no processing will be performed.

[0056] The above method obtains the power telemetry set and current telemetry set classified by bus according to the bus association relationship and telemetry type, and receives the power telemetry value in real time through subscription. When the power telemetry value changes, the active power and reactive power vector values of the bus to which the power telemetry belongs under this section are obtained. According to logical conditions such as amplitude and quality, the validity of its vector sum is judged. When the validity logic check passes or the system transmission timeout time threshold is reached, the system will send the current section power telemetry to the master station. This effectively solves the problem of unbalanced bus power data received by the master station due to reasons such as power grid fluctuations, sampling performance differences, and communication performance differences between measurement and control devices, and avoids the situation where the master station power data is not refreshed during long-term power grid fluctuations.

[0057] When the subscribed power telemetry changes, obtain the active power and reactive power vector values of the bus to which the power telemetry belongs under this section. The scanning principle is as Figure 3 shown. At time T 1 , the active power telemetry P i1 changes. The system obtains all the active power telemetry of the bus to which P i1 belongs and scans its real-time value. The acquisition method is as follows:

[0058] When the system is initialized, the forwarded telemetry data is divided into power telemetry points, current telemetry points, and other telemetry points, expressed as K = {W, A, O} (K: set of all system forwarded telemetry points, W: set of power telemetry points, A: set of current telemetry points, O: set of other telemetry points). The power telemetry point described above is a measurement model that describes the active power and reactive power characteristics of the intervals connected to the bus in the substation.

[0059] According to the association relationship between the power telemetry point, current telemetry point and the bus, the power telemetry point and current telemetry point are classified according to the bus, expressed as W = {S i} (S i : represents the set of active power telemetry points and reactive power telemetry points corresponding to bus i in the substation), A = {I i} (I i : represents the set of current telemetry points corresponding to bus i in the substation), where S i = {P i1 , P i2 ... P in , Q i1 , Q i2 ,... Q in},I i ={I i1 ,I i2 ,...I in}}。

[0060] Thus, when the power telemetry P i1 changes, the system finds the set S i1 of bus power telemetries that contains P i , and obtains all the active power telemetry points or reactive power telemetry points of this bus under S i (here, taking the change of the active power telemetry point P i1 as an example, the active power telemetry points P i1 ~P in in the set are obtained; if it is the change of the reactive power measurement point, the reactive power telemetry points in the set are obtained).

[0061] Taking Figure 3 the actual situation shown as an example, at this time n = 6, at time T 1 the active power telemetry point P i1 changes, and the real-time value after the change is P 1 , but the real-time values of P i2 , P i3 , P i4 , P i5 , P i6 have not been refreshed to the system database yet. In the system database, the corresponding values of the latter are the P 2 , T 3 , T 4 , T 5 , T 6 refreshed at the previous time, P 2m , P 3m , P 4m , P 5m , P 6m .

[0062] Calculated according to the values in the database at this time, the active vector sum of bus i is:

[0063] TP i =P 1 +P 2m +P 3m +P 4m +P 5m +P 6m ;

[0064] If the power grid load fluctuates greatly at this time, it is easy to have the situation that TP i exceeds the maximum load of this bus or the bus power is unbalanced, resulting in misjudgment by the master station. Therefore, add the validity logic check for the bus power telemetry and its vector sum total addition value, and the check process is as Figure 2As shown in the figure, the verification policy is as follows:

[0065] 1) The magnitude of the collected current of the measurement and control devices for all intervals of the busbar is not zero, that is, I ij > 0 (j = 1 to n, representing the jth current remote measurement point of busbar i);

[0066] 2) The measurement data quality of the measurement and control devices for all intervals of the busbar is not invalid or replaced. The specific data quality conforms to the data quality definition defined in IEC 60870-5-104 standard;

[0067] 3) The magnitudes of the sum of active power vectors and the sum of reactive power vectors do not exceed the over-limit values, the active power limit value △P and the reactive power limit value △Q, that is, TP i < △P, TQ i < △Q;

[0068] The magnitude and quality of the busbar interval current are taken into consideration mainly because of some special situations. For example, the communication interruption of the measurement and control device and the maintenance of the measurement and control device do not meet the upload conditions, thus affecting the upload frequency.

[0069] When the validity logic verification passes, the system uploads the real-time data of the scanned active power remote measurement point or the real-time data of the reactive power remote measurement point to the master station in the same data frame, and records the current time as T h ;

[0070] When the validity logic verification fails, if the absolute value of the time difference between the current time T c and T h is greater than the timeout value △t, the system also uploads the scanned active power remote measurement data or reactive power remote measurement data to the master station in the same data frame, and records the current time T h ; If the absolute value of the time difference between the current time T c and T h is less than or equal to the timeout value △t, no processing is performed;

[0071] The above-mentioned active power remote measurement points, reactive power remote measurement points, current remote measurement points, other remote measurement points, the association relationship between remote measurement points and the busbar, the active vector sum limit value, the reactive vector sum limit value, the timeout value, etc. all have corresponding configuration items in the system.

[0080] A timeout judgment module: starts timing from the last time it passed the verification or when the module was just started. If the validity verification of the real-time data of the telemetry point in the scanned section within the timeout period fails, it calls the data uploading module to upload the real-time values of each telemetry at the current time section. Whenever the real-time value of the section telemetry is uploaded to the master station, the timeout judgment module starts timing again.

[0081] A data uploading module: when the validity verification of the telemetry scanned in a certain section passes, or when triggered by the timeout judgment module, the system uploads the most recently saved section telemetry to the master station in a continuous frame message. The message is a data message that meets the frame format defined by the IEC60870-5-104 standard.

[0082] The corresponding active power telemetry point, reactive power telemetry point, current telemetry point, other telemetry points, the association relationship between the telemetry point and the bus, the limit value of the active vector sum, the limit value of the reactive vector sum, and the timeout time all have corresponding configuration items in the system.
