Embodiment 1

[0046] refer to figure 1 , is a flow chart of the control method for automatically detecting and adjusting load provided in Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation of detecting the load capacity running in the power supply line and adjusting the load of the power supply line. The method can be executed by a control device that automatically detects and adjusts loads, and the device can be implemented in the form of software and / or hardware, configured to be executed in a computer. The steps of this method are as follows:

[0047] Step S110: collecting electrical parameters of all electrical loads in the line.

[0048] As mentioned above, a line is a circuit composed of a power supply and a load connected to both ends of the power supply to consume electric energy, and can refer to a civilian or commercial power supply circuit. The load is an electronic component connected to both ends of the power suppl...

Embodiment 2

[0066] Embodiment 2 of the present invention also provides a control method for automatically detecting and adjusting loads. The difference between this method and Embodiment 1 is that it does not adjust according to the priority order of electric loads, but according to the current power loads running on the line. Make adjustments. The method includes:

[0067] Step S210, collecting electrical parameters of all electrical loads in the line.

[0068] As mentioned above, the process of collecting the electrical parameters of the electrical loads in the line has been described in detail in Embodiment 1, and will not be repeated here.

[0069] Preferably, the electrical parameters of the electrical load include current parameters and voltage parameters. Here, it is necessary to collect the current parameter and voltage parameter of each electric load.

[0070] Preferably, the preset rated capacity is the average value of the maximum load values ​​of all loads in the line. Her...

Embodiment 3

[0087] Such as figure 2 As shown, a control method for automatic detection and adjustment of load, including:

[0088] Step S300: Collect electrical parameters of all electrical loads in the line.

[0089] The collection module of the control device collects electrical parameters, and the electrical parameters include current parameters and voltage parameters.

[0090] Step S301: Calculate the total capacity of all electric loads on the line according to the collected current parameters and voltage parameters.

[0091] In this step S301, while calculating the total capacity of electric loads, it is also necessary to calculate the total capacity of all loads in the line, so that the sum of the total capacities of all loads is set as the safety threshold, and the average of the total capacities of all loads The value is set to the nominal capacity.

[0092]Step S302: Determine whether the total capacity of the electric load in the current period exceeds the preset rated capa...

Abstract

The invention discloses a control method and device for automatically detecting and adjusting loads. The control method comprises the steps that electric parameters of all the electricity loads in a circuit are collected; the total capacity of all the electricity loads is calculated according to the electric parameters of the collected electricity loads; whether the total capacity of the electricity loads exceeds a preset rated capacity or not is detected; all the electricity loads are adjusted when it is detected that the total capacity of the electricity loads exceeds the preset rated capacity. According to the control method and device, the personalized requirements of clients can be satisfied, and meanwhile peak staggering operation of all the loads can be achieved to the maximum degree; a load circuit can be automatically adjusted according to the rated capacity value of a system, so the automatic adjusting function of the circuit loads is achieved, and economy of the capacity of power distribution protection equipment is improved.

Description

technical field [0001] The invention relates to a power supply control system, in particular to a control method and device for automatically detecting and adjusting loads. Background technique [0002] With the rapid development of the economy, the power consumption of the primary, secondary and tertiary industries has increased year by year, especially the residential power consumption has increased sharply year by year, and the contradiction between power supply and demand has become more prominent. In some areas, electricity has become the main constraint on economic development. The power load gap is large, and the peak-to-valley difference increases. When the load rate decreases, the utilization rate of power generation equipment will be low, the coal consumption rate for power generation will increase greatly, and the cost of power production will increase. Power load is an important parameter in the power system, which refers to the power consumed by all electrical...
