The operating environment of the high-voltage switch room is greatly affected by the climate. When the external environment is severely humid, the environment in the switch room will also deteriorate due to severe moisture erosion, and condensation is very likely to occur, causing the insulation level of electrical equipment to decrease, resulting in frequent discharges, and even worse, explosions, which seriously threaten the safety of personnel and equipment and greatly increase the economic cost of power system operation.

[0056] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0057] See also Figure 1 The embodiment of the present application provides a switch room humidity monitoring method based on a centralized control system and an online monitoring device, comprising the following steps:

[0058] Step 1, acquiring multi-source collected data at the station end, wherein the collected data is collected by various sensors and detectors at the station end and transmitted to the substation centralized control system, and the collected data includes the operating status information and environmental data of the main and auxiliary equipment collected by various sensors and detectors at the station end;

[0059] Step 2, obtaining the temperature and humidity data inside the switch room, the temperature and humidity data outside the switch room, and the startup and operation status of the air conditioner, dehumidifier, and fan;

[0060] Step 3: Based on the joint analysis of indoor temperature and humidity data and outdoor temperature and humidity data, determine the startup and operation control strategy for the air conditioner, dehumidifier and fan, so that the temperature and humidity in the switch room are in the best state;

[0061] Step 4: When the temperature and humidity data in the switch room are abnormal, an early warning message is issued.

[0062] As the construction of substation centralized control system is gradually advanced, various sensors and detectors are deployed at the station end, collecting a large amount of main and auxiliary equipment operating status information and environmental data, and all data are uploaded to the centralized control platform. How to use this data to further realize the refined control and management of equipment and environment, and ensure the smooth, efficient and safe operation of all equipment, is a new issue we face.

[0063] In summer, it is hot and rainy, the air humidity is high, and the equipment runs at high load, which can easily cause equipment failure and affect the operation of the power grid. The switch room and the equipment in the secondary equipment room are sensitive to the ambient temperature and humidity. The traditional solution is to turn on the air conditioner for cooling when the indoor temperature is high, and turn on the air conditioner and dehumidifier for dehumidification when the humidity is high, and turn on the fan at the same time to speed up the indoor and outdoor air circulation. However, if it rains outside or the weather is hot and humid, the outdoor humidity is even higher, and turning on the fan may cause the indoor humidity to increase further. The embodiment of the present application provides a method for accurately judging a large amount of equipment operation status information and environmental data based on the substation centralized control system, and accurately and efficiently regulating and monitoring the switch room temperature and humidity.

[0064] In one implementation, in the above step 3, based on the joint analysis of indoor temperature and humidity data and outdoor temperature and humidity data, the startup and operation control strategy for the air conditioner, dehumidifier and fan is determined, including:

[0065] Step 31, obtaining the current indoor temperature, when the indoor temperature belongs to one of the second data range, the third data range, and the fourth data range, maintaining the current air conditioning operation state, the second data range, the third data range, and the fourth data range increase in sequence and do not intersect;

[0066] Step 32, when the indoor temperature is within the second data range and shows a downward trend, until it drops to the lower limit of the second data range, the air conditioner is started to turn on the heating mode, until the indoor temperature rises to the upper limit of the second data range, and the air conditioner heating mode is turned off; when the indoor temperature is within the second data range and shows an upward trend, until the indoor temperature rises to the upper limit of the second data range, the air conditioner heating mode is turned off;

[0067] Step 33, when the indoor temperature belongs to the fourth data range and shows an upward trend, the air conditioning cooling mode is started until it rises to the upper limit of the fourth data range, and the air conditioning cooling mode is turned off until the indoor temperature drops to the lower limit of the fourth data range; when the indoor temperature belongs to the fourth data range and shows a downward trend, the air conditioning cooling mode is turned off until the indoor temperature drops to the lower limit of the fourth data range.

[0068] It can be understood that when the indoor temperature belongs to one of the second data range, the third data range, and the fourth data range, the current air-conditioning operating state is maintained, and the current air-conditioning operating state may be: the process of the air-conditioning being turned on to increase the indoor temperature from the lower limit of the second data range to the upper limit of the second data range, the process of the air-conditioning being turned on to decrease the indoor temperature from the upper limit of the fourth data range to the lower limit of the fourth data range, the process of the air-conditioning not being turned on to allow the indoor temperature to float within the second data range, and the process of the air-conditioning not being turned on to allow the indoor temperature to float within the third data range or the fourth data range.

[0069] In one embodiment, in the above step 3, based on the joint analysis of indoor temperature and humidity data and outdoor temperature and humidity data, the startup and operation control strategy for the air conditioner, dehumidifier and fan is determined, including:

[0070] Step 34, obtaining current indoor relative humidity data, when the indoor relative humidity does not exceed the upper limit of the sixth data range, maintaining the current dehumidification equipment operation state, the dehumidification equipment includes a dehumidifier, an air conditioner in a dehumidification mode, and a fan, and the operation state includes starting and not starting;

[0071] Step 35, when the indoor relative humidity exceeds the upper limit of the sixth data range, start the dehumidification equipment to dehumidify, and turn off the dehumidification equipment when the indoor relative humidity drops to the lower limit of the sixth data range.

[0072] It can be understood that when the indoor relative humidity does not exceed the upper limit of the sixth data range, the current operating state of the dehumidification equipment is maintained. The current operating state of the dehumidification equipment includes: the dehumidification equipment is started to make the indoor relative humidity decrease from the upper limit of the sixth data range to the lower limit of the sixth data range, and the dehumidification equipment is not started to make the indoor relative humidity fluctuate within a range less than the upper limit of the sixth data range.

[0073] In one embodiment, in the above step 3, based on the joint analysis of indoor temperature and humidity data and outdoor temperature and humidity data, the startup and operation control strategy for the air conditioner, dehumidifier and fan is determined, including:

[0074] Step 351, the step obtains the indoor temperature, the first indoor relative humidity, the outdoor temperature, the first outdoor relative humidity, the indoor target stable temperature, and the indoor target relative humidity under the current operation strategy;

[0075] Step 352, calculating a preset indoor dehumidification total amount according to the indoor space volume, the current indoor first relative humidity, and the indoor target relative humidity;

[0076] Step 353, obtaining the dehumidification speed of the dehumidifier, the air conditioner in the dehumidification mode, and the fan at different working powers, wherein the dehumidification speed of the fan is determined based on the air volume per unit time*(outdoor second relative humidity-current indoor first relative humidity), wherein the outdoor second relative humidity represents the humidity of the outdoor air at the indoor target stable temperature after it is introduced into the room;

[0077] Step 354, adaptively optimize the startup operating time and working power parameters of the dehumidifier, air conditioner in dehumidification mode, and fan, and determine the optimal dehumidification equipment operation control parameters to ensure that the actual dehumidification total amount meets the preset indoor dehumidification total amount, the duration of the dehumidification process meets the preset duration requirement, and the total operating power consumption of the dehumidification equipment is minimized, wherein the product of the dehumidification speed of a single device and the operating time represents the dehumidification capacity of a single device.

[0078] In the present application, the operating time and working power parameters of the dehumidifier, the air conditioner in the dehumidification mode, and the fan are adaptively determined to complete the dehumidification within the preset time while minimizing the power consumption of the dehumidification equipment, thereby improving the efficiency of the dehumidification control process.

[0079] See also Figure 2 In one embodiment, before the above step 354, before adaptively optimizing the operation time and working power parameters of the dehumidifier, the air conditioner in the dehumidification mode, and the fan, it also includes analyzing whether the current outdoor humidity meets the conditions for starting the fan, including:

[0080] Step 35401, based on the current indoor and outdoor temperature and relative humidity data, determine the indoor and outdoor dew point temperatures;

[0081] Step 35402, calculating the outdoor second relative humidity after the outdoor air is introduced into the room according to the outdoor dew point temperature and the indoor target stable temperature; it can be understood that after the outdoor air is introduced into the room, the relative humidity of the air will change due to the change in the temperature of the air;

[0082] Step 35403, if the second outdoor relative humidity is less than the target indoor relative humidity range, turn on the fan;

[0083] Step 35404: If the current relative humidity indoors> the second relative humidity outdoors> the target relative humidity range indoors, turn on the fan until the relative humidity indoors drops to the second relative humidity outdoors, and then turn off the fan;

[0084] Step 35405: If the second outdoor relative humidity is greater than the current indoor relative humidity, the fan will not be turned on.

[0085] In the embodiment of the present application, the change in relative humidity after the outdoor air is introduced into the room is taken into account, and the second relative humidity of the outdoor air is calculated. Considering that the introduction of outdoor air into the room is conducive to the reduction of the indoor relative humidity, it can be considered to turn on the fan, that is, when the indoor dehumidification is needed, the fan can be turned on or not according to the scene requirements while turning on the dehumidifier; of course, if after the above analysis, the second relative humidity outdoors is greater than the current relative humidity indoors, when the indoor dehumidification is needed, dehumidification is performed by turning on the dehumidifier but the fan cannot be turned on.

[0086] In one embodiment, the above step 354, adaptively optimizing the startup operation time and working power parameters of the dehumidifier, the air conditioner in the dehumidification mode, and the fan, includes:

[0087] Step 35411, record the indoor space volume as V1, the current indoor first relative humidity a1, the indoor target relative humidity a2, the preset indoor dehumidification total amount W1; the preset dehumidification time is T, and the dehumidification speed of the dehumidifier, the air conditioner in the dehumidification mode, and the fan at the corresponding working power are recorded as V P1 、V P2 、V P3 ;

[0088] Step 35412, using the particle swarm algorithm to optimize the six parameters of the dehumidifier, the air conditioner in the dehumidification mode, the start-up operation time and the working power of the fan; the power is recorded as P1, P2, P3, and the operation time is recorded as t1, t2, t3; The actual dehumidification amount W2 = V P1 *t1+V P2 *t2+V P3 *t3=W1; total operating power consumption of dehumidification equipment P=P1*t1+P2*t2+P3*t3;

[0089] Step 35413, in the iterative optimization process, the total operating power consumption P of the dehumidification equipment is minimized as the target optimization function;

[0090] Step 35414, until the iteration termination condition is reached, the optimal dehumidification equipment operation control parameters are obtained.

[0091] In the embodiment of the present application, the working power of a single dehumidification device is designed to remain unchanged during the entire startup operation, and the corresponding t1, t2, and t3 durations are operated at the same working power. It can be understood that when it is determined that the fan does not meet the start-up conditions, the fan's operating time and working power parameters are both 0.

[0092] In another embodiment, the above step 354, adaptively optimizing the startup operation time and working power parameters of the dehumidifier, the air conditioner in the dehumidification mode, and the fan, includes:

[0093] Step 35421, record the indoor space volume as V1, the current indoor first relative humidity a1, the indoor target relative humidity a2, the preset indoor dehumidification total amount W1; the preset dehumidification time is T, and the dehumidification speed of the dehumidifier, the air conditioner in the dehumidification mode, and the fan at the corresponding working power is recorded as V P1 、V P2 、V P3 ;

[0094] Step 35422, assuming that the working power of each dehumidifier is different in different time periods during the entire dehumidification startup operation process, and the operating time at different working powers is different, use an intelligent optimization algorithm to optimize the working time and working power of multiple parameters of the dehumidifier, the air conditioner in the dehumidification mode, and the fan at different working powers during the entire dehumidification process; the operating time periods of a single dehumidifier are t1i, t2j, and t3k respectively; the working power of a single dehumidifier in the corresponding operating time period is recorded as P1i, P2j, and P3k, which respectively represent the working power of the dehumidifier in the i-th working time period of its entire dehumidification process, the working power of the dehumidifier air conditioner in the j-th working time period of its entire dehumidification process, and the working power of the fan in the k-th working time period of its entire dehumidification process; the total operating time of a single dehumidifier is recorded as t1, t2, and t3, i represents the i-th working time period of the dehumidifier during the entire working time, and the working power in the same working time period remains unchanged; j represents the jth working period of the dehumidifier air conditioner during the entire working time, and the working power in the same working period remains unchanged; k represents the kth working time period of the fan during the entire working time, and the working power in the same working time period remains unchanged; V P1i V represents the dehumidification speed of the dehumidifier at the working power of P1i in the i-th working period; P2j V represents the dehumidification speed of the air conditioner in dehumidification mode at the working power of P2j in the jth working period; P3k represents the dehumidification speed of the fan at the working power of P3k in the kth working period; Actual dehumidification amount Total operating power consumption of the dehumidification equipment

[0095] In the iterative optimization process, the total operating power consumption P of the dehumidification equipment is minimized and the total operating time of a single dehumidification equipment is maximized as the objective optimization function;

[0096] Until the iteration termination condition is reached, the optimal dehumidification equipment operation control parameters are obtained.

[0097] In the embodiment of the present application, the working power of each device in the entire dehumidification process is designed to be switched according to different time periods. Under the condition that the preset dehumidification process duration requirement is met and the total operating power consumption P of the dehumidification equipment is minimized, the operating time of a single device is extended as much as possible. It can be understood that in this case, the dehumidification speed of the entire dehumidification process is controlled to ensure that the dehumidification speed is slow, the working power of a single device is small, and the impact of the heat generated by the dehumidification equipment on the indoor temperature and the impact on the loss of the dehumidification equipment are reduced. Furthermore, in the present application, during the entire dehumidification process, according to the real-time monitored indoor relative humidity change process, the PID control algorithm can be used to optimize the indoor relative humidity change trend, thereby determining the dehumidification demand in the real-time unit time period according to the PID control amount, and then according to the dehumidification demand in the real-time unit time period, the intelligent optimization algorithm is used to optimize the working power parameters of the dehumidifier, air conditioner in dehumidification mode, and fan in the real-time unit time period during the entire dehumidification process, thereby obtaining different working power parameters of different equipment in different time periods. In combination with the PID control algorithm, the values ​​of i, j, and k are the same, and i, j, and k in the above formula can all be represented by any one of i or j or k. For example, if i, j, and k in the above formula are all represented by i, it represents the i-th time period in the entire dehumidification process, and the corresponding working power of different equipment in the i-th time period in the entire dehumidification process can be obtained, and then the corresponding working power of different equipment in different time periods in the entire dehumidification process can be obtained.

[0098] It can be understood that when it is determined that the fan does not meet the start-up conditions, the operating time and working power parameters of the fan are both 0.

[0099] In one embodiment, the second data range is 10°C to 18°C, the third data range is 18°C ​​to 20°C, and the fourth data range is 20°C to 25°C; the sixth data range is 50% to 65%; when the temperature and humidity reach the threshold at the same time, the humidity is responded to first.

[0100] In the embodiment of the present application, a temperature and humidity sensor is set to be linked with the air conditioner, dehumidifier and fan for control, and then the upper and lower limit thresholds are set for the device to realize automatic control according to the environmental change data. The system is designed with a control interface, and the operator can adjust the upper and lower limit values ​​of temperature and humidity as needed, which is convenient for operation. At the same time, it automatically distinguishes between summer and winter modes to deal with the problem that the air conditioner cannot start dehumidification when the temperature is too low in winter. Specifically for fan control, multiple temperature and humidity sensor data are collected indoors and outdoors at the same time. When the indoor humidity exceeds the threshold, the indoor and outdoor humidity values ​​are compared through an algorithm to analyze whether to start the fan. By starting the fan, a large amount of outdoor dry air is introduced to quickly reduce the indoor air humidity of the switch.
