Embodiment 1

[0097] Such as figure 1 As shown, a method for researching and judging the operating status of a substation based on the control cloud includes the following steps:

[0098] Step1: Read the equipment ledger data from the control cloud platform to obtain substation information and equipment information in the substation;

[0099] Step2: According to the equipment information in the substation, generate the topology connection model of the substation equipment;

[0100] Step3: Use the substation equipment topology connection model to obtain the provincial telemetry data sent by the provincial power supply company and the municipal telemetry data sent by the municipal power supply company;

[0101] Step4: Based on the connection relationship between the provincial telemetry data and the municipal telemetry data and the equipment in the substation, construct the operation status evaluation model, generate and display the evaluation report on whether the operation status is normal...

Embodiment 2

[0104] Embodiment 2: The difference between embodiment 2 and embodiment 1 is only that: the process of verifying the bus voltage balance model is described in detail.

[0105] 1. First, the remote signaling data of the circuit breaker sent to the control cloud by the municipal power supply company is used to judge the bus voltage balance verification model:

[0106] A reads the remote signaling data of the circuit breaker connected to the bus that is sent to the control cloud by the municipal power supply company,

[0107] Read the voltage data of the bus ab line sent to the control cloud by the municipal power supply company, and record it as Uc; read the rated voltage value of the bus bar as Ue, and take the bus voltage connected to the bus bar as Uc1, Uc2...

[0108] Ucn; the unit is kilovolts (kV). make

[0109]

[0110] Among them, B c is the running status of the data bus for ground adjustment, n is the number of circuit breakers connected to the bus, Yn is the rem...

Embodiment 3

[0160] Embodiment 3: The difference between embodiment 3 and embodiment 1 is only that: the process of calibrating the transformer apparent power model is described in detail.

[0161] 1. For 2-winding transformers:

[0162] 1. Read the remote signal value of the circuit breaker connected to the high-voltage side winding sent by the municipal power supply company to the control cloud from the control cloud database, denoted as Ych, and read the remote signal value of the circuit breaker connected to the low-voltage side winding as Ycl,

[0163] T c =Y ch +Y cl (10)

[0164] where T c It is the running status of the ground data transformer.

[0165] 2. Read the high-voltage side current, active power and reactive power sent to the regulating cloud by the municipal power supply company from the regulation cloud database and record them as Ich, Pch and Qch respectively, and record the low-voltage side current, active power and reactive power as Icl and reac...

Abstract

The invention discloses a transformer substation operation state research and judgment method based on regulation and control cloud and belongs to the technical field of power transfer automation. The method comprises the following steps of step 1, reading equipment ledger data from a regulation and control cloud platform, and obtaining the information of a transformer substation and the information of equipment in the transformer substation; step 2, generating a transformer substation equipment topological connection model according to the equipment information in the transformer substation; step 3, acquiring provincial telemetry data uploaded by a provincial power supply company and municipal telemetry data uploaded by a municipal power supply company by utilizing the transformer substation equipment topological connection model; and step 4, constructing an operation state evaluation model based on the connection relationship between the provincial telemetry data and the municipal telemetry data and the equipment in the transformer substation, and generating and displaying an evaluation report about whether the operation state is normal or not. According to the method, a problem that misjudgment, missed judgment and misjudgment are likely to occur in a traditional research and judgment mode is solved, the bus voltage balance verification model, the transformer apparent power verification model and the alternating current line current verification model are creatively provided, and research and judgment accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power mobilization automation, and in particular relates to a method for researching and judging the operating state of a substation based on a control cloud. Background technique [0002] There are multiple sets of data acquisition terminals on the substation site, which collect data independently and send them to the management systems of the two-level management agencies. For example, the substation in Hefei area will use different equipment to obtain data and send them to Hefei Electric Power Company and Anhui Electric Power Company respectively. . The data in the two systems do not communicate with each other. The Anhui provincial company and the Hefei city company will respectively adopt the traditional data inspection method to study and judge the data of the substation and obtain a conclusion on whether the substation is operating normally. The data values ​​received by different managem...
