Description

Technical Field

[0001] The present invention relates to a method and system for automatic point-to-point acceptance of a new energy centralized control system and a substation communication gateway, belonging to the technical field of data processing. Background Art

[0002] The substation communication gateway is an important hub device that connects the equipment in the new energy substation and the new energy centralized control system. It obtains the signal of the equipment in the new energy substation and sends the signal to the new energy centralized control system.

[0003] With the advancement of new power systems, new energy centralized control systems are constantly being built, expanded, and renovated. New energy substations and new energy centralized control systems need to be manually verified point by point repeatedly. The point-to-point work is redundant and requires a lot of manpower and time. Before point-to-point, it is necessary to clearly check the information and make a point table; during point-to-point, the new energy centralized control master station and the debugging personnel at the new energy substation end contact by phone to manually check the data received by the new energy centralized control master station with the actual data of the new energy substation. The substation debugging personnel also need to use debugging tools to manipulate the opening and closing of switches and knife switches and the addition of voltage and current. Especially for new energy wind turbines, inverters, junction boxes, battery stacks of energy storage power stations and other equipment, the signal scale is particularly large, and a single substation can even reach hundreds of thousands of points. At the same time, the equipment that is generating electricity and running does not have the conditions for power outage point-to-point, which has led to the delay in point-to-point work. In the actual project implementation, construction and commissioning are heavily dependent on the substation monitoring system manufacturers, and the construction, supervision, and owner units lack rigorous acceptance and control methods. The early commissioning tasks are actually relatively rough and are transferred to the subsequent stages. These problems cause the new energy centralized control automation operation and maintenance personnel to face tight time, heavy tasks, and insufficient carrying capacity in their work, which may cause the information access and commissioning work to be unable to be completed on time, thus affecting the overall project commissioning plan. Summary of the invention

[0021] A method for automatic point-to-point acceptance of a new energy centralized control system and a substation communication gateway comprises the following steps:

[0022] S1. The new energy centralized control master station sends a message to the substation communication gateway to summon the substation's full data point table. The substation sends the full data point table of the entire station to the master station. The master station analyzes the full data point table sent by the substation and selects the full data point table according to the needs of the master station. The master station sends the selected point table to the substation;

[0023] S2. The substation confirms the received point table, confirms that the point table sent by the master station is included in the full data point table of the substation, and returns the confirmation result to the master station. The master station determines the confirmation result. If the confirmation result is correct, the set value information is added to the confirmed point table to form an operating data point table.

[0024] S3. The master station sends a call command to the substation according to the generated operation data point table, and accepts the telesignaling, telemetering, telepulse and digital quantity information sent by the substation according to the operation data point table.

[0025] Furthermore, in step S3, the acceptance of remote signaling, remote measurement, and remote pulse information includes:

[0026] The master station sends the start command to the substation according to the generated operation data telesignal point table. The substation generates position changes point by point according to the point table sequence. The position change mode is close first and then open.

When the "set value" and "sent value" of the same point number are completely consistent, the acceptance is considered to be passed. Otherwise, the acceptance is considered to have failed.

[0027] The master station sends the start command to the slave station according to the generated operation data telemetry point table. The slave station sets the floating point telemetry value according to the point table sequence and sends it to the master station. The master station analyzes the telemetry value sent by the slave station and updates it to the master station database. The master station compares the operation data telemetry point table with the master station database telemetry information. The operation data telemetry point table contains the point number, description, and set value, and the database telemetry information contains the point number, description, and sent value. When the "set value" and "sent value" of the same point number are completely consistent, it is considered that the acceptance has passed, otherwise it is considered that the acceptance has failed.

[0028] The master station sends the start command to the slave station according to the generated operating data remote pulse point table. The slave station sets the integer remote pulse value according to the point table order and sends it to the master station. The master station parses the remote pulse value sent by the slave station and updates it to the master station database. The master station compares the operating data remote pulse point table with the remote pulse information in the master station database.

When the "set value" and "upload value" of the same point number are exactly the same, the acceptance is considered to have passed. In other cases, the acceptance is considered to have failed.

[0029] Furthermore, in step S3, the acceptance of the digital quantity includes:

[0030] The master station converts the digital quantity into the first telesignal name according to the generated digital quantity point table of the operating data, and sends the start command to the substation at the same time. The substation sets the integer digital quantity value according to the point table order and sends it to the master station. The master station parses the digital quantity value sent by the substation and converts it into the second telesignal name. The master station compares the digital quantity point table of the operating data with the digital quantity information of the master station database, wherein the digital quantity point table of the operating data contains the point number, description, and set value telesignal name, and the set value telesignal name is the first telesignal name, and the digital quantity information of the database contains the point number, description, and uploaded value telesignal name, and the uploaded value telesignal name is the second telesignal name. When the "set value telesignal name" and the "uploaded value telesignal name" of the same point number are exactly the same, it is considered that the acceptance has passed, otherwise it is considered that the acceptance has failed

By setting an automatic point-to-point acceptance function module on the centralized control master station side, an automatic point-to-point system is formed between the master station and the substation, and the communication gateway automatically accesses the self-defined point-to-point system. According to the communication interaction between the master station and the substation, the manual import of the point table is abandoned, and the operation data point table can be automatically generated to ensure the accuracy of the description; the master station uses the generated remote signaling, remote measurement, remote pulse, and digital quantity operation data point table as the basis to compare the consistency between the substation sent value and the master station display value, and the acceptance of the master station system and the substation's communication gateway constitute a closed-loop acceptance system, realizing automatic point-to-point acceptance of remote signaling, remote measurement, remote pulse, and digital quantity, and realizing rapid acceptance.
