Detailed Description
The invention is described in further detail below in connection with fig. 1-5.
The embodiment of the invention discloses a VR-based power inspection method. The execution main body is a control system, and three modes can be achieved by adding a parallel circuit in the power transmission line and selecting the parallel circuit through a change-over switch: the original power transmission line transmits power alone; the original power transmission line and the parallel circuit jointly transmit power; the original power transmission line does not transmit power, and the parallel circuit transmits power.
Referring to fig. 1, the embodiment of the present invention at least includes steps S10 to S40.
S10, detecting the load of the power grid in real time, and adjusting the generated energy.
The power grid load is also called as electric load, and is the sum of electric power taken by electric equipment to the power grid at one moment, and the power grid load is continuously changed along with time.
Specifically, the system detects the power grid load in real time, adjusts the power generation amount of the generator set according to the power grid load, and accordingly supplies power to electric equipment, and keeps the situation that the power grid does not generate excessive power under the condition that the interference of other commands is avoided.
And S20, if the detected power grid load is larger than a preset standard value, starting the standby power line to split the load.
The standby power line is selected through the change-over switch and is connected with the power transmission line in parallel, and the standard value is set by the power plant according to the local power consumption condition.
Specifically, when the system detects that the power grid load is larger than a preset standard value, the system switches the standby line according to the change-over switch to jointly transmit power, so that load distribution is performed on the power transmission line, and further the current density in the line is reduced, so that the line loss in power line transmission is reduced.
And S30, if the power grid load is detected to be smaller than the preset minimum value, the generator set is turned off and the standby electric quantity is started.
The minimum value is set by the power plant according to the energy storage capacity of the standby electric quantity and the local electricity consumption wave situation. In this embodiment, the spare electric power is the stored electric power of the pumped storage power station.
Specifically, when the system detects that the power grid load is smaller than the minimum value, the power grid load is indicated to be close to the trough of the local power consumption, the standby power is enough to supply power to the power consumption equipment, the system closes the generator set and supplies power by using the standby power, and therefore the operation of the generator set when the load of the generator set is lower is reduced, and the working efficiency of the generator set is improved. It should be understood that the generator set cannot be completely shut down, and the shutdown of the generator set in the present invention allows the generator to idle, thereby achieving minimum operating efficiency, rather than completely shutting down the generator.
And S40, calculating the line loss rate according to a preset line loss formula, and if the line loss rate is detected to be larger than a preset threshold value, replacing the power transmission line.
The line loss formula is as follows: (electricity generation amount-electricity consumption amount)/(electricity generation amount). Line loss rate is a measure of the loss of power in a power transmission line. The threshold is derived from the line loss rate test of the power plant under normal conditions.
Specifically, the system calculates the line loss rate of the power transmission line according to the line loss formula, if the line loss rate is detected to be larger than the threshold value, the system replaces the corresponding power transmission line according to the change-over switch, and uses the parallel standby line to perform power transmission, so that the line loss in the power transmission is reduced, the power production cost is further reduced, and the power production benefit is improved.

The power database is set in advance by the power plant according to the power grid framework, and comprises information such as the position of each power transmission line, the power transmission line corresponding to the change-over switch and the like. The transmission line refers to a power transmission line in which a circuit load is larger than a preset value. The preset value is set by the power plant according to the power transmission capability of the power transmission line.
Specifically, after the system detects that the power grid load is greater than a preset value, the system detects circuit loads of all transmission lines in the power grid, searches for the transmission lines with the circuit loads greater than the preset value, then searches for a change-over switch corresponding to the transmission circuit in the power database, and turns on the change-over switch, so that the transmission line and the standby circuit are connected in parallel, further, load distribution is carried out on the transmission line, current density in the transmission line is reduced, and loss of power in the transmission line is reduced.
In some embodiments, referring to fig. 3, step S30 specifically includes steps S301 to S302.
S301, if the power grid load is detected to be smaller than the minimum value, the generator set is turned off;
s302, starting the pumped storage power station, closing the pumped storage power station and starting the generator set according to the power grid load until the power consumption of the storage power station is finished or the power grid load is detected to be not smaller than the minimum value.
Specifically, when the system detects that the power grid load is smaller than the minimum value, the system indicates that the power consumption requirement is small at the moment, the system turns off the generator set and turns on the pumped storage power station until the electric quantity of the pumped storage power station is used up or the power grid load is detected to be not smaller than the minimum value, the system turns off the pumped storage power station and turns on the generator set according to the power grid load to generate electricity, so that the generated energy of wave crests and wave troughs of the power grid is regulated through the pumped storage power station, the difference value of the generated energy of wave crests and wave troughs is reduced, and the running efficiency of the generator is increased.
In some embodiments, considering the problem of storing energy in the pumped-storage power station, for storing energy in the pumped-storage power station, the corresponding processing steps are as follows: if the power grid load is detected to be in the preset energy storage interval, starting all the generator sets to generate full load power; storing the residual electric quantity in a pumped storage power station; and adjusting the generated energy according to the load of the power grid until the energy storage of the pumped storage power station reaches the upper limit.
The energy-storable section is set by the power plant according to local electricity consumption wave crest and wave trough conditions and the full-load power generation power of the generator, and the energy-storable section is generally set to be close to the wave trough.
Through adopting above-mentioned technical scheme, when detecting that the electric wire netting load is in the energy storage interval of predetermineeing, the system opens all generating sets and carries out full load electricity generation to increase generating efficiency of generating set, the system stores the electric quantity that the electric wire netting is unused, in the surplus electric quantity to the pumped storage power station promptly, until the energy storage of pumped storage power station reaches the upper limit, opens generating set according to the electric wire netting load and generates electricity, thereby increase generating efficiency of generating set, and then be convenient for carry out energy storage to the pumped storage power station, so that the generated energy of the crest trough of electric wire netting is adjusted to the pumped storage power station.

s403, searching a power transmission line with the line loss rate larger than a threshold value;
s404, searching a standby switch corresponding to the power transmission line in a preset power database;
s405, turning on a standby switch to replace the power transmission line.
The electricity selling quantity is the electricity consumption quantity of the electric equipment at the current moment. The backup switch is a change-over switch for switching a circuit connected in parallel with the power transmission line.
Specifically, the system detects the generated energy and the sold electric quantity of the power grid, the system subtracts the sold electric quantity from the generated energy and divides the calculated electric quantity to obtain the line loss rate, if the line loss rate of the power grid is larger than a threshold value, the system calculates the line loss rate of each section of line in the power grid, then the system searches a standby switch corresponding to the power transmission line in the power database, and the system opens the standby switch, so that the power transmission line is replaced, and the replacement of the power transmission line with overlarge line loss is facilitated, so that the loss of current transmitted in the circuit is reduced.
In some embodiments, considering the problem of searching for a line with an excessively high line loss rate, in order to quickly search for a line with an excessively high line loss, the corresponding processing steps are as follows: detecting the power generation amount and the sales amount of a preset primary circuit, and calculating the line loss rate of the primary circuit according to a line loss formula; searching a secondary circuit corresponding to the primary circuit with the line loss rate larger than the threshold value in a preset line database; calculating the line loss rate of the secondary circuit, and searching a tertiary circuit corresponding to the secondary circuit with the line loss rate larger than the threshold value in the line database; and searching a standby switch corresponding to the tertiary circuit with the line loss rate larger than the threshold value in the power database.
