[0002] The environment control system of an electrical system refers to an auxiliary system that creates and maintains a suitable operating environment for electrical equipment or electrical rooms through temperature and humidity adjustment, air purification, and air distribution, etc. The core function of the system is to ensure that the equipment works reliably and safely under stable temperature and humidity and cleanliness conditions, effectively prevent environmental factors such as overheating, condensation, dust, and corrosive gases from causing insulation deterioration, failure, and even safety accidents of electrical equipment, thereby prolonging the service life of the equipment, improving the operation stability, and reducing the maintenance cost.
[0003] The existing electrical system environment, such as a data center, has a control strategy that aims to maintain a set interval. In actual operation, when the environmental parameters approach the set threshold, although the system can intervene when detecting abnormal parameters, the electrical equipment is usually sensitive to environmental changes, and the target parameters have reached a critical state when the system takes measures. The environmental control system often intervenes too late, and the electrical equipment may be damaged, even leading to more serious risk accidents. The environmental control system is often passive in adjusting the environmental parameters of the electrical system, and its response time cannot meet the demand for rapid adjustment.

[0087] D2=(ZXi(t0)+di,ZXi(t0)+2di,……,ZXi(t1));
[0088] D3=(ZXi(t1)+di,ZXi(t1)+2di,……,ZXi(t1)+b×di);
[0089] Where i is each element in the execution vector ZX, and a and b are the critical coefficients when the slope of the respiratory entropy and the change acceleration reach the preset threshold;

Control the parameters of the execution vector ZX in the control area marked as abnormal, select only one parameter as the variable parameter each time, and the absolute value of the parameter value increment of the variable parameter is di, where i is the parameter number of the execution vector ZX;
[0091] After changing the output value of the variable parameter, the load parameter, the actuator parameter and the environment parameter in the control area with the abnormal flag are collected and preprocessed, the respiratory entropy curve of the load parameter, the actuator parameter and the environment parameter is drawn, the slope curve is calculated by the first-order difference, and the change acceleration curve is calculated by the second-order difference, and the slope curve and the change acceleration curve are defined as the control group;

[0103] By collecting the load parameters, actuator parameters and environmental parameters of the electrical system, the breathing entropy of the environmental control system is calculated to reflect the efficiency of the system operation. When the operation efficiency is abnormal, based on the multi-level protection of the expensive equipment in the electrical system, the sensitivity of the environmental parameters is lower than that of the fan wall and power distribution unit which are low-cost and large-number devices. According to the control area division of the actuator distribution, the execution parameter test of the control area is carried out. Through gradient test and real-time analysis, the change trend of the system parameters can be accurately identified, so as to judge which parameters will affect the system operation.

Control the execution vector ZX parameters in the abnormal marked control area as a variable, only one parameter is selected as a variable parameter each time, and the absolute value of the increment of the parameter value of the variable parameter is di, where i is the parameter number of the execution vector ZX; After changing the output value of the variable parameter, the load parameters, actuator parameters and environment parameters in the abnormal marked control area are collected and preprocessed, the respiratory entropy curve of the load parameters, actuator parameters and environment parameters is drawn, and the slope curve is calculated by first-order difference, and the change acceleration curve is calculated by second-order difference. The slope curve and the change acceleration curve are defined as the control group; The current value of the slope curve at t0+t2 in the control group is obtained, the absolute value of the difference between the current value and the termination parameter is calculated and recorded, so as to obtain the slope difference value sequence; The current value of the change acceleration curve at t0+t2 in the control group is obtained, the absolute value of the difference between the current value and the termination parameter is calculated and recorded, so as to obtain the change acceleration difference value sequence; Wherein, the t2 is the time point when the slope curve of the respiratory entropy is less than the preset threshold after changing the parameters of the execution vector ZX; The gradient test is performed on each parameter of the execution vector ZX, and the slope difference value sequence set and the change acceleration difference value sequence set are obtained; S503. Analyze the slope difference value sequence set, calculate the absolute value of the difference between two adjacent elements in the slope difference value sequence set, mark it as the increment difference value, find the parameter value of the first element before the first increment difference value greater than the preset difference value according to the test gradient sorting of S501, and define the parameter value as the executable margin of the parameter. It represents the maximum value that the execution parameter can output when the system is safely running, that is, the executable margin; Wherein, the preset difference value is obtained by the operator based on historical data analysis; The analysis of the change acceleration difference value sequence set finds the first change acceleration difference value greater than the preset change acceleration difference value of the previous parameter value, defines the parameter value as a warning value, and calculates the ratio of the actual value of the parameter to the warning value , ∈ (0, 1] wherein the The closer to 1, the greater the probability that the environmental control system will have an accident. The closer it is to 0, the more stable the environmental control system is; Wherein, the preset change acceleration difference value is obtained by the operator based on historical data analysis; S504. The operation and maintenance personnel constrain the actual output value of the parameter according to the executable margin of the parameter corresponding to the execution vector ZX in S503, and the constraint condition is as follows: setting the actual maximum output value of the parameter in the execution vector ZX as 60% of the executable margin of the parameter. By setting a pre-warning proportion threshold of the parameters of the execution vector ZX When ≥ Immediately investigate the related equipment in the corresponding control area.
