[0087] Reference Figure 1 - Figure 4 As shown, a method for intelligent management and control of power generation safety based on power system construction in an embodiment of the present invention includes:

[0088] Acquiring power generation system information, wherein the power generation system information includes power generation area information, electrical area information, and functional area information;

[0089] According to the power generation system information, the power generation system parameter information is acquired, wherein the power generation system parameter information includes the power generation system temperature information, the power generation system vibration information, the power generation system electrical information and the power generation system pressure information;

[0090] According to the power generation system parameter information, the power generation system status is evaluated to obtain the power generation system regional safety index;

[0091] According to the regional safety index of the power generation system, the power generation area, electrical area and functional area are further divided to obtain regional classification information;

[0092] Specifically, different regions are divided according to the regional safety index of the power generation system to obtain regional classification information, including:

[0093] Acquiring environmental information, wherein the environmental information includes environmental temperature information, environmental humidity information, and environmental pressure information;

[0094] Obtaining regional basic safety factor based on environmental information, power generation system parameter information and power generation system standard parameter information;

[0095] Acquiring environmental meteorological data according to the environmental information, wherein the environmental meteorological data includes meteorological type information and meteorological intensity information;

[0096] Obtain the regional safety index of the power generation system based on the regional basic safety factor and environmental meteorological data;

[0097] Based on the power generation safety control requirements, a first threshold value of the power generation system regional safety index and a second threshold value of the power generation system regional safety index are obtained;

[0098] According to the power generation system regional safety index, the first threshold of the power generation system regional safety index and the second threshold of the power generation system regional safety index, the region is divided to obtain regional classification information, wherein the regional classification information includes warning region information, buffer region information and safety region information;

[0099] Among them, the calculation formula of regional foundation safety factor is:

[0100]

[0101] Where Q is the regional basic safety factor, α is the regional function influence coefficient, T is the power generation system temperature, T0 is the power generation system standard temperature, T1 is the ambient temperature, P is the power generation system pressure, P1 is the ambient pressure, μ i is the safety impact factor of the i-th electrical index of the power generation system, A i is the value of the i-th electrical index of the power generation system, a iis the standard value of the ith electrical index of the power generation system, D is the basic safety index of the power generation system, and n is the total number of electrical indicators of the electrical system.

[0102] In this scheme, the regional basic safety factor is obtained through environmental information, power generation system parameter information and power generation system standard parameter information. Through the regional basic safety factor, the safety status of different areas of the power generation system can be evaluated, which is convenient for the subsequent division of the area and improves the efficiency of power generation control.

[0103] It is understandable that the electrical indicators of the power generation system, such as current, voltage, power, etc., often reflect the working condition of the entire system. By analyzing the electrical data, an accurate assessment of the status of the power generation system can be achieved.

[0104] Control power generation safety based on regional classification information;

[0105] Specifically, power generation safety is managed and controlled based on regional classification information, including:

[0106] Based on the power generation safety control requirements, a first threshold value of the power generation system regional safety index and a second threshold value of the power generation system regional safety index are obtained;

[0107] Acquiring regional classification information according to the regional safety index of the power generation system, the first threshold of the regional safety index of the power generation system, and the second threshold of the regional safety index of the power generation system;

[0108] According to the regional classification information, restrict the access of personnel and equipment in different areas;

[0109] If the power generation system regional safety index is higher than the first threshold of the power generation system regional safety index, the current location is in the warning area;

[0110] If the power generation system regional safety index is lower than the first power generation system regional safety index threshold and higher than the second power generation system regional safety index threshold, the current position is located in the buffer area;

[0111] If the power generation system regional safety index is lower than the second threshold value of the power generation system regional safety index, the current location is in a safe area;

[0112] The calculation formula of the regional safety index of the power generation system is:

[0113]

[0114] Where E is the regional security index of the power generation system, β j is the intensity of the i-th weather, ρ j is the safety impact coefficient of the ith weather type, L is the distance between the current location and the center of the region to which it belongs, and Z(β j, τ) is the safety impact coefficient of the regional center distance, where β j ≥β j0 ,but If β j <β j0 , then Z(β j , τ) = τ, β j0 is the intensity threshold of the i-th weather type, and m is the total number of environmental meteorological types.

[0115] In this scheme, regional classification information is obtained through the regional safety index of the power generation system. According to the regional classification information, access restrictions are imposed on personnel and equipment in different areas. The power generation system divides the area affected by the entire power generation system into power generation area, electrical area and functional area according to different functional units. The safety conditions of different locations in different areas are different. Through the regional safety index of the power generation system, the first threshold of the regional safety index of the power generation system and the second threshold of the regional safety index of the power generation system, the power generation area, electrical area and functional area are further divided to form warning areas, buffer areas and safety areas. Different areas are set with different regional permissions and equipment permissions to achieve the management and control of power generation safety.

[0116] It is understandable that weather type and intensity have a higher impact on power generation safety. For example, in rainy weather, the impact of moderate rain and heavy rain on power generation safety is not the same as the impact of light rain on power generation safety.

[0117] According to the power generation system parameter information, determine whether the power generation system state is abnormal. If not, record the power generation system parameter information and environmental meteorological data, and obtain the power generation system historical parameter information and historical environmental meteorological data;

[0118] Specifically, judging whether the power generation system state is abnormal based on the power generation system parameter information includes:

[0119] Acquiring regional basic safety factor information, wherein the regional basic safety factor information includes a power generation area basic safety factor, an electrical area basic safety factor, and a functional area basic safety factor;

[0120] Acquire abnormal parameter information of the power generation system according to the power generation system parameter information and the power generation system standard parameter information;

[0121] Obtain the power generation system safety risk index based on the power generation system abnormal parameter information and regional basic safety factor information;

[0122] Based on the power generation safety management and control requirements, obtain the power generation system safety risk index threshold;

[0123] According to the power generation system safety risk index and the power generation system safety risk index threshold, it is judged whether the power generation system state is abnormal. If the power generation system safety risk index is lower than the power generation system safety risk index threshold, the power generation system state is normal; if the power generation system safety risk index is higher than the power generation system safety risk index threshold, the power generation system state is abnormal;

[0124] Among them, the calculation formula of the power generation system safety risk index is:

[0125]

[0126] Where R is the power generation system safety risk index, μ i is the safety impact factor of the i-th electrical index of the power generation system, A i is the value of the i-th electrical index of the power generation system, a i is the standard value of the i-th electrical index of the power generation system, Q1 is the regional basic safety factor of the power generation area, Q2 is the regional basic safety factor of the electrical area, Q3 is the regional basic safety factor of the functional area, and n is the total number of electrical indicators of the electrical system.

[0127] In this solution, the abnormal parameter information of the power generation system is obtained through the power generation system parameter information and the standard parameter information of the power generation system. The safety risk index of the power generation system is obtained based on the abnormal parameter information of the power generation system and the regional basic safety factor information. By quickly identifying problems and issuing alarms, it helps operators respond quickly and minimize the impact of accidents.

[0128] Match the historical parameter information of the power generation system and the historical environmental meteorological data with the date as the matching tag to obtain the historical data set of the power generation system;

[0129] Based on the construction of power system, obtain the standard parameter information of power generation system;

[0130] Obtain power generation system operation and maintenance information based on power generation system historical data sets and power generation system standard parameter information;

[0131] Specifically, based on the historical data set of the power generation system and the standard parameter information of the power generation system, the power generation system operation and maintenance information is obtained, including:

[0132] According to the historical data set of the power generation system and the standard parameter information of the power generation system, the historical difference data of the power generation system is obtained;

[0133] Obtain basic operation and maintenance frequency information based on historical difference data of the power generation system;

[0134] Obtain historical regional basic safety factors based on historical data sets of power generation systems;

[0135] Obtain the operation and maintenance frequency correction factor based on the historical difference data of the power generation system and the historical regional basic safety factor;

[0136] Obtaining power generation system operation and maintenance information based on basic operation and maintenance frequency information and operation and maintenance frequency correction coefficient;

[0137] Among them, the operation and maintenance frequency of the power generation system is specifically:

[0138]

[0139] Where, f is the operation and maintenance frequency of the power generation system, k is the operation and maintenance frequency correction coefficient, f1 is the basic operation and maintenance frequency, A i is the value of the i-th electrical index of the power generation system, a i is the standard value of the i-th electrical indicator of the power generation system, f0 is the standard operation and maintenance frequency of the power generation system, Q1 is the regional basic safety factor of the power generation area, Q2 is the regional basic safety factor of the electrical area, Q3 is the regional basic safety factor of the functional area, σ is the variance of Q1, Q2 and Q3, and n is the total number of electrical indicators of the electrical system.

[0140] In this scheme, the basic operation and maintenance frequency information is obtained through the historical difference data of the power generation system, and the operation and maintenance frequency correction coefficient is obtained according to the historical difference data of the power generation system and the historical regional basic safety factor. The operation and maintenance information of the power generation system is obtained according to the basic operation and maintenance frequency information and the operation and maintenance frequency correction coefficient. The operation and maintenance strategy of the power generation system is adjusted through the basic operation and maintenance frequency information and the operation and maintenance frequency correction coefficient, thereby significantly reducing the risk of accidents and enhancing the safety and reliability of the power system.

[0141] It is understandable that in the actual power generation process, the power generation conditions are often changeable, and the power generation system cannot be maintained by setting a fixed operation and maintenance frequency.

[0142] Maintain the power generation system based on the power generation system operation and maintenance information.

[0143] Specifically, judging whether the power generation system state is abnormal based on the power generation system parameter information also includes:

[0144] If the power generation system status is abnormal, the power generation system safety risk index and the power generation system regional safety index are obtained;

[0145] According to the power generation system safety risk index and the power generation system regional safety index, the power generation system regional safety index under the power generation system abnormal state is obtained;

[0146] According to the regional safety index of the power generation system under the abnormal state of the power generation system, the regional classification information is adjusted to obtain the classification information of the abnormal power generation area;

[0147] Control power generation safety based on classification information of abnormal power generation areas;

[0148] Among them, the calculation formula of the regional safety index of the power generation system under abnormal state of the power generation system is:

[0149]

[0150] Where E' is the regional safety index of the power generation system under abnormal conditions, E is the regional safety index of the power generation system, R is the safety risk index of the power generation system, Q is the regional basic safety factor, and σ is the variance of the regional basic safety factors of the power generation area, electrical area, and functional area.

[0151] In this scheme, the power generation system regional safety index under abnormal power generation system status is obtained through the power generation system safety risk index and the power generation system regional safety index. According to the power generation system regional safety index under abnormal power generation system status, the regional classification information is adjusted to obtain the abnormal power generation regional classification information. According to the abnormal power generation regional classification information, the power generation safety is controlled.

[0152] It is understandable that abnormal power generation status often leads to reduced power generation safety, and the safety status of the power generation system area will also change accordingly. By analyzing the regional safety under abnormal power generation conditions, adjustments can be made to different regional ranges.
