[0002] In recent years, with the rapid development of social economy, the demand for social electricity consumption has increased rapidly, resulting in a large number of power distribution facilities. The capacity of power distribution facilities is usually determined according to the maximum load of the actual equipment in the running cycle, which is a transient value at a certain time section. However, in the actual system operation, the time period when the load reaches the peak value is very small, resulting in long-term light load of power distribution facilities. Therefore, improving the utilization rate of power distribution facilities and ensuring the reliability of power supply are crucial for power distribution facility enterprises to improve their operating level and power supply capacity.

[0025] like Figure 1 As shown, the present invention provides a technical solution: a method for calculating and optimizing the utilization rate of facility power distribution, comprising the following steps:

[0026] S1: Obtain parameters of power distribution facilities;

[0027] The parameters of the power distribution facilities include rated voltage, rated current, rated frequency, rated capacity, etc.

[0028] S2: Obtain overloaded lines and overloaded lines in the region according to the line load rate of the power distribution facilities;

[0029] The load rate calculation formula of the power distribution facilities is as follows:

[0030] Load rate = average load in a certain period (e.g. one month, one week) ÷ maximum load in the period;

[0031] Average load = system power in a certain period ÷ operating hours in the period;

[0032] S3: Then analyze the reasons that can affect the energy efficiency of the power distribution facilities according to the overloaded lines and overloaded lines;

[0033] The reasons that can affect the energy efficiency of the power distribution facilities according to the overloaded lines and overloaded lines include voltage three-phase imbalance, current three-phase imbalance, high or low load rate, overload, etc.

[0034] S4: Remind the customer in a visual way;

[0035] The visual way includes color visualization, graphical visualization and conceptual visualization;

[0036] Color visualization: the strength and detail of the target value are expressed through the depth of color, which is a common method of data visualization planning. Customers can see which part of the target data value is more prominent at a glance.

[0037] Graphical visualization: when planning targets and data, using graphics with corresponding actual meaning to present together will make the data chart more vividly displayed, making it easier for customers to understand the theme expressed by the chart;

[0038] Conceptual visualization: when converting general target data into simple and familiar data, users can more easily understand the meaning expressed by the chart;

[0039] S5: Then combine the capacity / need data declared in the marketing basic file to calculate the transformer load rate for the customer, and according to the electricity data, calculate the power distribution facility utilization rate index;

[0040] The power distribution facility utilization rate index is divided into "high" for more than 90%, "medium+" for more than 60% and less than 90%, "medium-" for more than 30% and less than 60%, and "low" for less than 30%.

[0041] The power distribution facility utilization rate is the ratio of the actual maximum load of the transformer to its rated capacity.

[0043] Optimization recommendations include reducing peak valley difference, demand side management technical measures, optimization of reactive power compensation;

[0044] Reduce peak valley difference: load factor refers to the ratio between the average load and the maximum load. The load curve can accurately reflect the load rate, if the load rate is higher, it means that the load curve is more flat, and the power utilization rate is higher. Therefore, try to reduce the use of electricity in peak, reduce the fill valley to make the load curve more stable, effectively improve the load rate, so that the utilization rate of equipment is improved;

[0045] Demand side management technical measures: DSM technology mainly aims at people's living habits and production technology characteristics in a certain period of time to improve the technology, at present, energy saving and management timing and a certain use of electrical equipment to high energy consumption ultimately changed the user's electricity usage habits; improve the efficiency of user side power consumption, this behavior with the help of advanced energy-saving equipment and technology, while its ultimate goal is also to be able to save the expenditure of electric energy;

[0046] Optimization of reactive power compensation: if the lack of reactive power line will lead to the increase of current, the optimization can make the current decrease, at the same time improve the stability and utilization rate of power distribution network.

[0047] The power distribution facility utilization rate calculation optimization method includes the following steps when used: obtaining the parameters of the power distribution facility; according to the line load rate of the power distribution facility, the heavy load line and the overload line in the region are obtained; then the reasons affecting the energy efficiency of the power distribution facility are analyzed according to the heavy load line and the overload line; the reasons are reminded to the customer in a visual way; then combined with the capacity / need data declared in the marketing basic file, the transformer load rate is calculated for the customer, according to the power consumption data, the power distribution facility utilization rate index is calculated; finally, through the power distribution facility utilization rate index to give the corresponding energy efficiency optimization recommendations.
