Problems solved by technology

[0005] However, with the expansion and development of the power grid, the number of substations is increasing day by day, and the workload of substation staff entering the high-voltage room is huge
Faced with the rapid increase in the number of AVC operations, but with limited scheduling and monitoring personnel, the existing technical means of manual switching and blocking can no longer meet the real-time and intelligent needs of on-site operation management.

Embodiment 1

[0047] Such as figure 1 As shown, a method for automatically deactivating the AVC when a person enters the hyperbaric room comprises the following steps:

[0048]S1. Set a normally open infrared sensor switch in the high pressure room to detect whether people have entered,

[0049] S2. Upload the infrared sensor switch value output by the infrared sensor switch to the master station device through the switch value transmission link,

[0050] S3. Associate the infrared sensor switching value received by the master station device as a SCADA protection signal, and send the infrared sensor switching value together with the SCADA protection signal to the AVC protection logic, and set the trigger priority level of the infrared sensor switch value to the highest (Such as figure 2 shown);

[0051] S4. The output of the AVC protection logic is used as the output of the input AVC state quantity or the exit AVC state quantity of the master station device, and is transmitted to the AV...

Embodiment 2

[0060] Such as figure 1 As shown, a system for automatically deactivating AVC when a person enters a hyperbaric room includes:

[0061] Located in the high-voltage room, it is used to generate the infrared sensor switching value according to whether the person enters the normally open infrared sensor switch,

[0062] The switch value transmission link used to transmit the infrared sensor switch value to the master station device;

[0063] The master station device for inputting or exiting the AVC state quantity to the AVC switch cabinet according to the infrared sensor switch quantity output;

[0064] AVC switchgear used to perform input or exit actions according to the input or output status;

[0065] When the infrared sensor switch does not detect people, it outputs the switch value of the open state, which is represented by 0.

[0066] When the infrared sensor switch detects a person, it outputs the switch value of the closed state, which is represented by 1;

[0067] W...

Abstract

The invention discloses a method and a system for automatically stopping AVC (Automatic Voltage Control) when a person enters a high-voltage chamber. The system comprises a normally-open infrared induction switch which is positioned in the high-voltage chamber and is used for generating an infrared induction switching value according to whether the person enters the high-voltage chamber, and a switching value transmission link which is used for transmitting the infrared induction switching value to a main station device, the main station device which is used for outputting the AVC input statequantity or the AVC exit state quantity to the AVC switch cabinet according to the infrared induction switching value, and the AVC switch cabinet which is used for performing an input action or an output action according to the input or output state quantity; when the infrared induction switch does not detect a person, the infrared induction switch outputs a switching value in an on state, the switching value is expressed by 0; when the infrared induction switch detects a person, the infrared induction switch outputs a switching value in an off state, and the switching value is expressed by 1;the main station device outputs an input AVC state quantity when acquiring an on-state switching value, and outputs an exit AVC state quantity when acquiring an off-state switching value.

Description

technical field [0001] The invention relates to the field of AVC switching on and off control, and mainly relates to a method and a system for automatically deactivating an AVC when a person enters a high-pressure room. Background technique [0002] AVC (Automatic Voltage Control) system refers to the online optimization calculation through real-time monitoring of reactive power / voltage conditions of the whole network under normal operating conditions, and through adjusting and controlling the reactive power output of the power grid, the on-load tap changer tap gear Position and compensation equipment switching status, to meet the optimal reactive power flow operation under the grid security constraints, to achieve the purpose of high voltage and minimum network loss. [0003] According to the requirements: "Whoever enters the power distribution room and capacitor room must temporarily exit the AVC switchgear system of the station and prohibit remote and local operation (inc...
