[0002] A substation is a power equipment in the power system that transforms voltage, receives and distributes electric energy, controls the flow direction of electricity, and regulates voltage, and has important uses. During the use of the substation, due to problems such as electrical equipment failures and aging and short-circuiting of lines, fires are extremely likely to occur.

At present, an automatic fire extinguishing system is mainly installed in the substation. When a fire occurs, the fire extinguishing system is automatically activated to achieve rapid fire extinguishing. The currently used automatic fire extinguishing system cannot detect fires in a timely manner. Only when a fire occurs can it respond, and the response speed is slow, and timely actions and feedback cannot be carried out. Summary of the Invention

The risk type includes a safe state, a warning state, and a dangerous state, and the location of the risk abnormal equipment in the substation is analyzed, the risk abnormal equipment information is output, and the location of the risk abnormal equipment is used as a risk abnormal point; A risk warning step. When the risk type is the warning state, according to the risk abnormal point information and historical adjustment information, a warning adjustment strategy is used to adjust the pipeline pressure of the fire-fighting equipment and the water level of the pressure dividing pool; A fire extinguishing step.

When the risk type is in the warning state or the dangerous state, the electrical equipment includes fire-fighting equipment and electrical equipment. Calculate the current loads of the fire-fighting equipment and the electrical equipment respectively, and compare them with the main power supply load. Through the backup power startup algorithm, analyze whether the main power supply load meets the current load of the fire-fighting equipment. If not, start the backup power supply.

[0013] Preferably, the warning adjustment strategy includes a pipeline adjustment step and a voltage-dividing pool adjustment step. The pipeline adjustment step is used to obtain the pipeline pressure corresponding to the risk abnormal point, and a pressure threshold is preset.

The voltage-dividing pool adjustment step obtains the water levels of all voltage-dividing pools in the substation, and according to the position of the risk abnormal point, the priority ranking strategy ranks the voltage-dividing pools in priority order. According to the water level of the voltage-dividing pool and the priority order, the water in the voltage-dividing pool with a lower priority is transported to the voltage-dividing pool with a higher priority to realize the water level adjustment in the voltage-dividing pool.

[0014] Preferably, the priority ranking strategy includes an information acquisition step, which acquires the water levels of each voltage-dividing pool and the positions of the corresponding fire-fighting equipment and risk abnormal points of each voltage-dividing pool; a priority acquisition step, which divides the response levels according to the positions of the fire-fighting equipment corresponding to the voltage-dividing pool and the risk abnormal points. The response levels include a startup level, a standby level, and a supply level. The priority ranking is in turn the startup level, the standby level, and the supply level. According to the water level in the voltage-dividing pool from high to low, the voltage-dividing pools in the standby level are ranked in priority order, and according to the water level in the voltage-dividing pool from low to high, the voltage-dividing pools in the supply level are ranked in priority order.

When the water level of the voltage-dividing pool in the supply level changes, the priority of the voltage-dividing pool in the supply level is re-ranked, and a supply threshold is set.

When the risk type is the dangerous state, according to the location of the risk abnormal point, it monitors the state of the risk abnormal point and outputs a fire extinguishing instruction through fire analysis; A load management module. When the risk type is the warning state or the dangerous state, the electrical equipment includes fire-fighting equipment and electrical equipment. It calculates the current loads of the fire-fighting equipment and the electrical equipment respectively, compares them with the main power supply load, and analyzes whether the main power supply load meets the current load of the fire-fighting equipment through a backup power supply start strategy. If not, the backup power supply is started.

[0020] The beneficial effects of the present invention: During the use of the substation, the electrical equipment in the substation is detected, the risk value of each electrical equipment is calculated, and the risk type of the electrical equipment is divided according to the risk value, including a safe state, a warning state, and a dangerous state. When it is in the safe state, it means that the equipment is operating normally. When it is in the warning state, the equipment may be abnormal and a fire may occur. When it is in the dangerous state, it means that a fire has occurred; For the risk abnormal equipment in the warning state, the corresponding fire-fighting equipment is warned, the pressure of the corresponding fixed pipeline and the water level of the pressure dividing pool are adjusted to achieve warning, ensuring that the fire-fighting equipment can respond in time and extinguish the fire in time when a fire occurs, and avoiding the spread of the fire; For risk-abnormal devices in a dangerous state, corresponding fire extinguishing measures are taken.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] The following further details the embodiments of the present invention in conjunction with the accompanying drawings: The substation fire layout control method includes Data collection step, which is used to obtain the device information of the electrical equipment in the substation. The device information includes device parameters and operation parameters, and is also used to obtain environmental parameters. The device parameters include basic information such as device type, model, location, etc. The operation parameters include electrical parameters such as current and voltage. The environmental parameters include temperature, humidity, gas concentration, smoke concentration, etc.; Risk assessment step, which obtains the environmental parameters, device parameters, and operation parameters in the data collection step, and after processing according to the environmental parameters, device parameters, and operation parameters, calculates the risk of the electrical equipment through a risk assessment algorithm to obtain a risk value. The risk assessment algorithm can obtain the risk value of each electrical equipment through the risk matrix assessment algorithm. The risk assessment algorithm quantifies the probability of fire occurrence based on the current data and historical data to obtain the possibility, and quantifies the severity of the consequences based on the hazards caused by the fire. The hazards include casualties, property losses, fire spread, etc., and obtains the risk value through the possibility and severity of the hazard time. The higher the risk value, the greater the possibility of fire occurrence; According to the actual standards and historical data of the substation, several risk threshold ranges are preset. The risk threshold ranges include the thresholds for the safe state, warning state, and dangerous state. By comparing the risk value with the preset several risk threshold ranges, the risk type is output. The risk type includes the safe state, warning state, and dangerous state. Analyze the location of the risk abnormal equipment in the substation, output the risk abnormal equipment information, and use the location of the risk abnormal equipment as the risk abnormal point. According to the layout and equipment information of the substation, analyze the location of the risk abnormal equipment in the substation, determine the risk abnormal point, and record and output the data such as the name, model, location, and risk type of the risk abnormal equipment for subsequent processing and maintenance; Risk warning step, when the risk type is the warning state, according to the risk abnormal point information and historical adjustment information, use the warning adjustment strategy to adjust the pipeline pressure of the fire protection equipment and the water level of the pressure dividing pool; when the risk type is the warning state, automatically start the warning adjustment strategy according to the risk abnormal point information and historical adjustment information, and according to the warning adjustment strategy, automatically increase the pipeline pressure of the fire protection equipment and the water level of the pressure dividing pool. Through warning adjustment, pre-adjust the pipeline pressure of the fire protection equipment and the water level of the pressure dividing pool to ensure that when the current device risk value increases, the fire protection equipment can respond in time and take measures against the risk abnormal equipment in time to avoid the spread of fire; The warning adjustment strategy includes a pipeline adjustment step and a pressure dividing pool adjustment step, Pipeline adjustment steps are used to obtain the pipeline pressure corresponding to the risk abnormal point, and a pressure threshold is preset. The pipeline pressure is compared with the pressure threshold. If the pipeline pressure is less than the pressure threshold, the pipeline pressure is adjusted; obtain the pipeline pressure data of the fire-fighting equipment corresponding to the risk abnormal point, and according to the safety operation standard of the fire-fighting equipment, preset a reasonable pressure threshold. When the pipeline pressure is greater than the pressure threshold, the fire-fighting equipment can be immediately started to shorten the response time. Compare the real-time management pressure with the preset pressure threshold. If the pipeline pressure is less than the pressure threshold, increase the pipeline pressure through an adjustment device such as a booster pump to ensure that the pipeline pressure of the fire-fighting equipment corresponding to the risk abnormal point meets the usage requirements and can respond in time during the fire extinguishing process to shorten the reaction time; Voltage-dividing pool adjustment steps: obtain the water levels of all voltage-dividing pools in the substation, and perform priority ranking on the voltage-dividing pools according to the position of the risk abnormal point and the priority ranking strategy. According to the water levels of the voltage-dividing pools and the priority order, transport the water in the voltage-dividing pool with a lower priority to the voltage-dividing pool with a higher priority to achieve the adjustment of the water level in the voltage-dividing pool; obtain the water level data of all voltage-dividing pools in the substation in real time, and according to the position of the risk abnormal point, the layout of the substation, the distribution of equipment, the degree of urgency, etc., specify a priority ranking strategy to perform priority ranking on the voltage-dividing pools to ensure that the voltage-dividing pool with a higher priority can be replenished with water first in case of emergency; according to the water level and priority order of the voltage-dividing pool, use adjustment equipment such as water pumps to transport the water in the voltage-dividing pool with a lower priority to the voltage-dividing pool with a higher priority to achieve the dynamic adjustment of the water level in the voltage-dividing pool and ensure that the fire-fighting equipment has sufficient water supply pressure in case of emergency.

[0026] The priority ranking strategy includes Information acquisition steps: obtain the water levels of each voltage-dividing pool, and obtain the positions of the fire-fighting equipment corresponding to each voltage-dividing pool and the risk abnormal point. Obtain the water level data of all voltage-dividing pools in the substation in real time, and obtain the position information of the fire-fighting equipment corresponding to each voltage-dividing pool to determine the position information of the risk abnormal point and the relative distance between the risk abnormal point and the fire-fighting equipment; Priority acquisition step: According to the fire-fighting equipment corresponding to the pressure-dividing pool and the location of the risk abnormal point, the response levels are divided. The response levels include the start level, the standby level, and the supply level. The priority order is the start level, the standby level, and the supply level in sequence. According to the positional relationship between the fire-fighting equipment corresponding to the pressure-dividing pool and the risk abnormal point, the pressure-dividing pool is divided into different response levels. The response levels include the start level, the standby level, and the supply level. Among them, the start level has the highest priority. The pressure-dividing pool of the response level is directly associated with the fire-fighting equipment directly associated with the risk abnormal point. The standby level is the second priority and is the pressure-dividing pool corresponding to the fire-fighting equipment closer to the discovered abnormal point. When the risk value of the risk abnormal point is relatively high, the pressure-dividing pool within the standby level can also supply water to start its corresponding fire-fighting equipment. The supply level is the lowest priority and supplies water to the pressure-dividing pool within the start level when necessary. According to the water level in the pressure-dividing pool from high to low, the pressure-dividing pools within the standby level are sorted by priority. Within the standby level, the pressure-dividing pools are sorted by priority according to the water level from high to low, ensuring that during use, the pressure-dividing pool with a higher water level can respond in a timely manner. And according to the water level in the pressure-dividing pool from low to high, the pressure-dividing pools within the supply level are sorted by priority. Within the supply level, the pressure-dividing pools are sorted by priority according to the water level from low to high, ensuring that when using the pressure-dividing pool within the supply level to supply water to the pressure-dividing pool within the start level, the pressure-dividing pool with a higher water level is preferentially selected, ensuring that there is water in all pressure-dividing pools, without affecting the normal operation, and providing sufficient water for the pressure-dividing pool within the start level.

[0027] Priority adjustment step: During the process of adjusting the water level of the pressure-dividing pool, the water level of the pressure-dividing pool is collected in real time. When the water level of the pressure-dividing pool within the supply level changes, the priority of the pressure-dividing pools within the supply level is re-sorted. And a supply threshold is set. When the water level in the pressure-dividing pool is lower than the supply threshold, the current pressure-dividing pool exits the priority sorting. During the process of adjusting the water level of the pressure-dividing pool, the water levels of each pressure-dividing pool are collected in real time to better monitor the water levels of the pressure-dividing pools. When the water level of the pressure-dividing pool within the supply level changes, either decreases due to water supply or increases due to water replenishment, the priority of the pressure-dividing pools within the supply level is re-sorted according to the latest water level data. A supply threshold is set for each pressure-dividing pool. When the water level in the pressure-dividing pool is lower than the supply threshold, it exits the priority sorting. While ensuring that the water supply pool meets its own use requirements, it supplies water to the pressure-dividing pool within the start level. According to the real-time water level data and the priority sorting results, the water flow between the pressure-dividing pools is dynamically adjusted to ensure that sufficient water can be provided to the fire-fighting equipment near the risk abnormal point preferentially in case of emergency.

[0028] Fire extinguishing steps: When the risk type is in a dangerous state, based on the location of the risk anomaly point, monitor the status of the risk anomaly point, and output a fire extinguishing instruction through fire ignition analysis; when it is detected that the risk type is in a dangerous state, that is, a fire has occurred, monitor based on the location of the risk anomaly point and the turntable, and output a specific fire extinguishing instruction through fire ignition analysis; The fire ignition analysis includes sub-steps for determining the degree of fire. Obtain the thermal imaging image in the substation, and based on the location of the risk anomaly point, determine the corresponding image to be analyzed. According to the image to be analyzed, determine the location of the fire point, the equipment on fire, and the fire temperature, calculate and obtain the fire parameters, and based on the fire parameters, retrieve the corresponding fire extinguishing sequence from the fire extinguishing database. The fire extinguishing sequence is preset with corresponding fire extinguishing instructions, and the fire extinguishing instructions include the spraying angle, spraying time, and spraying volume; The system obtains the thermal imaging data in the substation, which can intuitively display the temperature distribution of each electrical equipment, quickly locate the fire point and potential fire points. According to the location of the risk point, select the corresponding image to be analyzed from the thermal imaging image, analyze the image to be analyzed, determine the specific location of the fire point, the information of the equipment on fire, and the fire temperature. Based on the information of the fire point, calculate a series of fire parameters, such as the fire area, the speed of fire spread, etc. According to the calculated fire parameters, retrieve the corresponding fire extinguishing sequence from the fire extinguishing database. The fire extinguishing sequence is set with fire extinguishing instructions for different fire situations, and the fire extinguishing instructions include the spraying angle, spraying time, and spraying volume, etc.

[0029] It also includes a fire extinguishing adjustment step. According to the fire parameters, index in the historical fire table to obtain a fire situation with a relatively high similarity, and obtain the corresponding historical fire parameters and historical fire extinguishing instructions, and use an adjustment algorithm to adjust and output the fire extinguishing instructions; To further improve the accuracy of fire extinguishing, adopt the fire extinguishing adjustment step to adjust the fire extinguishing instructions. According to the current fire parameters, index in the historical fire table to obtain a historical fire situation with a relatively high similarity, and use the historical fire situation with a relatively high similarity for reference; According to the indexed historical fire situation, obtain the corresponding historical fire extinguishing instructions, and use the adjustment algorithm to adjust the current fire extinguishing instructions to ensure that the fire extinguishing instructions can be more in line with the actual needs of the current fire situation based on the actual situation of the substation, and output the adjusted fire extinguishing instructions to the fire fighting equipment for specific fire extinguishing operations; Through the fire extinguishing adjustment step, the accuracy and efficiency of fire extinguishing can be further improved, and the threat of fire to the safety of the substation equipment and personnel can be reduced.

[0030] The adjustment algorithm includes:

[0031]

[0032]

[0033]

[0034] where R is the adjustment parameter, F(x) is the function of the ignition point position, x is the coordinate of the ignition point position, G(y) represents the function of the ignition degree, y is the ignition degree value, H(z) is the ignition device, and z is the type of the ignition device. is the injection angle function. is the injection angle value. is the injection volume function. is the injection volume, T(t) is the injection time function, t is the injection time, L(m) is the function of the historical ignition parameter, K(m) is the function of the historical fire extinguishing instruction, and m is the number of historical data. are the adjusted injection angle, injection volume, and injection time respectively.

[0035] It also includes a power management step. When the risk type is judged to be in the warning state and a risk threshold is preset, when the risk value is greater than the risk threshold, the power supply of the risk abnormal device is cut off. There is a preset risk threshold, and the risk threshold is used to judge whether the current risk reaches the level that requires power supply cut-off. When it is detected that the risk type is in the warning state, the risk value is obtained and compared with the preset risk threshold. If the risk value is greater than the risk threshold, the power supply of the risk abnormal device is automatically cut off to prevent the occurrence of a fire caused by electrical failures or other reasons. When the risk type is in the dangerous state, the ignition parameters in the ignition degree determination step are obtained, and according to the ignition comparison table, the fire level is obtained, and the corresponding power cut-off measures are obtained according to the fire level. When the risk transition is judged to be in the dangerous state, the ignition parameters are obtained, and according to the ignition parameters, the fire level is determined by referring to the ignition comparison table. The ignition comparison table is a table related to the equipment. According to different ranges of the ignition parameters, the fire is divided into different levels, and the fire levels include minor fire, moderate fire, and severe fire. According to the determined fire level, the corresponding power cut-off strategy is obtained from the power cut-off measure database. When a minor fire occurs, only the power supply of the risk abnormal device needs to be cut off. When a moderate fire occurs, the fire may spread, and the power supply of the electrical equipment within a certain range of the risk abnormal point needs to be cut off. When a severe fire occurs, that is, the fire cannot be controlled in time, all the power supplies in the substation are cut off. According to the actual fire situation, the risk abnormal type and the fire level can be accurately judged, and corresponding measures can be taken in time to ensure the normal operation of the substation as much as possible while ensuring safety.

[0036] Load management steps. When the risk type is in the warning state or the dangerous state, the electrical equipment includes fire-fighting equipment and electrical equipment. Calculate the current loads of the fire-fighting equipment and the electrical equipment respectively, and compare them with the main power supply load. Through the backup power startup algorithm, analyze whether the main power supply load can meet the current load of the fire-fighting equipment. If not, start the backup power. When the risk type is in the warning state, calculate the current loads of the fire-fighting equipment and the electrical equipment respectively. The current load of the fire-fighting equipment is based on factors such as the operating power and operating time of the equipment. The calculation of the electrical equipment involves parameters such as the load rate of the transformer and the current of the line. Compare the calculated current loads of the fire-fighting equipment and the electrical equipment with the load of the main power supply to evaluate whether the main power supply can meet the power demands of all current equipment. If the main power supply load cannot meet the current load of the fire-fighting equipment, then start the backup power startup algorithm to analyze whether to start the backup power supply. If the analysis result of the backup power startup algorithm shows that the backup power supply needs to be started, then automatically start the backup power supply. When the risk type is in the dangerous state, it is necessary to consider the potential impact of the fire on the power load, reallocate the power load according to the backup power startup algorithm, give priority to ensuring the power supply of the fire-fighting equipment, and at the same time minimize the load of the electrical equipment. When the main power supply cannot meet the power demands of the fire-fighting equipment, immediately switch to the backup power supply to ensure that the fire-fighting equipment can continue to operate during emergencies such as fires and provide support for fire extinguishing work.

H(x) represents the backup power reference value; There is a preset backup power threshold. When the backup power reference value is greater than the backup power threshold, then start the backup power supply. Otherwise, there is no need to start the backup power supply.

The data acquisition step is used to obtain the equipment information of the electrical equipment in the substation. The equipment information includes equipment parameters and operating parameters, and is also used to obtain environmental parameters; A risk assessment module calculates a risk value through a risk assessment algorithm based on environmental parameters, equipment parameters, operating parameters, etc., compares the risk value with a number of preset risk threshold ranges, outputs a risk type according to the comparison result. The risk types include a safe state, a warning state, and a dangerous state, analyzes the location of the risk-abnormal equipment in the substation, outputs risk-abnormal equipment information, and uses the location of the risk-abnormal equipment as a risk-abnormal point; A risk warning module, when the risk type is in a warning state, retrieves an adjustment sequence from a fire database according to the risk-abnormal point information.
