Problems solved by technology

In recent years, compared with the ever-increasing pressure of distribution network production and operation, distribution network automation operation monitoring management is relatively lagging behind, as shown in: management methods are still extensive; operation and maintenance points are extensive, manpower and material resources are insufficient; necessary safety technical equipment is lacking Many unfavorable factors, such as no information on faults or delayed feedback, have resulted in high and frequent faults in the distribution network, especially distribution transformers, frequent damage to equipment and facilities, difficult accident handling, long cycle, and a large number of customers affected by faults. wide
The problems in the distribution network directly affect the image of power supply companies, affect the harmonious relationship between suppliers and users, and cause economic losses and negative social impacts that cannot be ignored

Embodiment

[0022] Example: see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 .

[0023] The method for real-time control of transformer load, the steps are:

[0024] a. The voltage detection device and the current detection device collect the power consumption data of the secondary side of the transformer;

[0025] b. The temperature collection and transmission module collects line temperature and transformer top oil temperature, and the environmental monitoring device detects the temperature, humidity and wind speed of the environment;

[0026] c. The controller calculates the average oil temperature based on the data detected in steps A and B, the average oil temperature and the data of the heating time manually input to obtain the thermal resistance, and the heat capacity is obtained by manually inputting the oil weight and device weight parameters of the transformer;

[0027] d. The controller obtains the thermal circuit model through the obtained thermal resistance...

Abstract

The invention discloses a transformer load real-time control method comprising the following steps: electricity consumption data of the secondary side of a transformer, the temperature of a circuit, and the top oil temperature of the transformer are acquired; an environment monitoring device detects the environment temperature, humidity and wind speed; and the temperature difference of the transformer winding, the hot spot and the line oil is worked out through a thermal circuit model, and a two-dimensional figure is generated. According to the transformer load real-time control method of the invention, the transformer load real-time control technology is researched and improved by taking into consideration multiple factors including transformer running state, load and environment, warning is carried out for transformer defects, and the transformer load improving ability and duration are comprehensively considered to achieve the goal of fine and intelligent transformer load running management.

Description

Technical field: [0001] The invention relates to a control system, in particular to a method for real-time control of transformer load. Background technique: [0002] With the continuous development of the domestic economy, the electricity consumption of residents and enterprises is increasing day by day. In order to solve the contradiction between supply and demand, a large number of equipment upgrades have been done for power transformation and transmission. In recent years, compared with the ever-increasing pressure of distribution network production and operation, distribution network automation operation monitoring management is relatively lagging behind. The specific manifestations are: the management methods are still extensive; the operation and maintenance points are wide and the manpower and material resources are insufficient; the necessary safety technical equipment is lacking. There are many unfavorable factors such as no information or delayed feedback on fault...
