Embodiment Construction

[0033] The invention relates to a control method of an electronic load regulator of a generator, which is suitable for the control of the electronic load regulator under the single-unit isolated network operation of the generator. Such as figure 1 As shown, the generator electronic load regulator control method includes the following steps:

[0034] Step S110: Acquiring measured frequencies and control parameters of multiple virtual water tanks in real time.

[0035] The multiple virtual water tanks are obtained by dividing the load resistance tanks, and the frequency of each virtual water tank is collected in real time, and the control parameters of the virtual water tanks refer to the frequency of use of a given voltage. The function of the load resistance box is to dissipate heat, to ensure that the excess electric energy is consumed through the conversion of heat energy, so as to achieve load balance. There are two loads in the load water resistance box of the generator....

Abstract

The invention relates to a control method and system for an electronic load regulator of a generator. The measured frequencies and control parameters of a plurality of virtual water tanks are respectively obtained in real time, and the deviation value of each virtual water tank is calculated according to the measured frequency and the received control frequency, and the deviation value of each virtual water tank is obtained according to the deviation Values ​​and control parameters are calculated to obtain the control step size of each virtual water tank. According to the control step of each virtual water tank, the total control step of the load resistance tank is calculated, and then the thyristor control step of the electronic load regulator is calculated and output, so as to realize the frequency stability adjustment of the three-phase current. Obtain the current value and frequency value of the three-phase current of the generator, and calculate and output the given value of the three-phase current of the generator according to the current value and frequency value of the three-phase current, which is used to control the three-phase current balance of the generator . The electronic load regulator is controlled through frequency balance and current balance to avoid three-phase imbalance due to load changes and improve the safety of the generator.

Description

technical field [0001] The invention relates to the technical field of generator sets, in particular to a control method and system for a generator electronic load regulator. Background technique [0002] With the rapid development of power grid technology, the overhead lines in some remote places transmit electricity from the power grid, which is very costly, and even the construction of elevated lines in these places is technically difficult and risky. Therefore, local water resources can be used for hydro turbine power generation, electronic loads can be used to adjust frequency, and a control device for frequency adjustment and harmonic control can be invented to solve the quality of electricity used by nearby residents. [0003] The electronic load regulator is used to maintain the constant frequency of the generating set, and switch the guide vanes through the electric operating mechanism to realize the turning on and off of the generating set. However, due to the lar...
