Description

Technical Field

[0001] The invention relates to a power regulation characteristic modeling and system of an electrolytic zinc load, belonging to the technical field of electrolytic zinc load modeling. Background Art

[0002] Since renewable energy generation is random and volatile, it poses a huge challenge to the frequency stability of the power grid, and also gradually increases the requirements for the flexible regulation capability of the power system. It is obviously insufficient to rely solely on the regulation resources on the power generation side to maintain the stability of the system frequency. It is urgent to tap more load-side adjustable resources to participate in the power grid power regulation to jointly maintain the stability of the power system. High-energy loads have the advantages of large regulation capacity and high regulation flexibility and have gradually become a research hotspot. At present, there have been some studies on typical high-energy loads such as electrolytic aluminum loads and polysilicon loads at home and abroad. However, the current research on high-energy loads at home and abroad is limited to several typical high-energy loads. In fact, if we can tap the regulation potential of more typical high-energy loads and guide them to participate in the public rate regulation of the power grid, it will greatly alleviate the regulation pressure of the power grid.

[0003] As a typical high-energy-consuming load, electrolytic zinc load accounts for a high proportion in some coastal provinces with rich lead and zinc ore resources. However, due to the particularity and complexity of the production process of electrolytic zinc load, there is currently no research on the power regulation characteristics of electrolytic zinc load.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] It should be understood that the step numbers used in this document are only for convenience of description and are not intended to limit the order in which the steps are executed.

[0070] It should be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0071] The terms “include” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0072] The term "and / or" means and includes any and all possible combinations of one or more of the associated listed items.

[0073] Embodiment 1:

[0074] In order to solve the problem of unclear power regulation characteristics of high-energy-consuming electrolytic zinc load, a power regulation characteristic modeling method of electrolytic zinc load is proposed. Based on the production process of electrolytic zinc load, its power adjustable links are analyzed, and the power characteristics of the adjustable production equipment are modeled. Thus, the power regulation model of electrolytic zinc load is obtained to assist the research on high-energy-consuming load participating in power grid power regulation.

[0075] See also Figure 1 This embodiment provides a method for modeling power regulation characteristics of electrolytic zinc load, comprising the following steps:

[0076] S100, analyzing the process flow of electrolytic zinc load to determine the process flow of electrolytic zinc load;

[0077] S200, analyzing the process flow of the determined electrolytic zinc load, and determining the power adjustable link and corresponding power adjustable equipment in each process flow;

[0078] S300: Analyze the adjustable parameters of the corresponding power and perform power regulation characteristic modeling.

[0079] As a preferred implementation of this embodiment, the process flow for determining the electrolytic zinc load includes:

[0080] The production of electrolytic zinc load is a multi-process production process that requires cooperation among various production links.

[0081] The first step is the raw material preparation and pretreatment process. First, the zinc ore needs to be broken into smaller particles using crushing equipment to facilitate subsequent grinding and flotation. Then, the crushed zinc ore is further ground using grinding equipment to improve the flotation effect. The zinc-containing minerals and gangue minerals are separated by bubbles using re-selection equipment to increase the zinc content of the zinc ore. Subsequent links all rely on the raw materials provided by the pretreatment link.

[0082] The second step is the acid leaching process, in which the zinc ore is placed in an acid leaching tank containing a sulfuric acid solution for an acid leaching reaction; then a stirring device is used to stir the solution during the acid leaching process to promote the reaction; finally, a filtering device is used to separate the acid leaching solution from the solid residue to obtain a solution containing zinc ions.

[0083] The third step is the electrolysis process, in which an electrolyte containing zinc ions is passed into the electrolytic cell, and then a current of several hundred or even thousands of amperes is passed through it to reduce metallic zinc on the cathode plate through electrolysis.

[0084] As a preferred implementation of this embodiment, the determining of the corresponding power adjustable device in each process flow includes:

[0085] The first link involves crushing equipment, grinding equipment and flotation equipment. Crushing equipment generally uses jaw crushers, cone crushers, etc. In actual applications, the width of the discharge port can be changed by replacing lining plates of different thicknesses or adjusting the position of the crushing cone, thereby adjusting the crusher power. The production equipment in this link is adjustable production equipment; grinding equipment generally uses ball mills, and the power it consumes depends on its speed. The speed can be reduced by increasing the grinding medium to reduce power consumption, or the speed can be increased by installing a frequency converter, etc., which will increase power consumption and is a power-adjustable device; flotation equipment generally uses a flotation machine, which is generally equipped with a frequency converter. The output frequency of the frequency converter can be changed to change the speed of the motor, thereby adjusting its power, and is a power-adjustable device.

[0086] The second link involves the acid leaching tank, stirring equipment and filtering equipment; the power of the acid leaching link is not adjustable; the stirring equipment generally uses a mixer equipped with a frequency converter, which can change the motor speed by adjusting the output frequency of the frequency converter, thereby achieving power adjustment; the filtering equipment generally uses a filter, and adjusting the pressure of the filter can change its filtering speed, thereby achieving power adjustment, which is a power adjustable device;

[0087] The third link, the electrolytic cell, is the core equipment in the electrolytic zinc load production process. Since the electrolytic cell has a certain heat storage capacity, short-term power adjustment will not have a significant impact on its production. That is, the electrolytic cell is also a power-adjustable device.

[0088] As a preferred implementation of this embodiment, the steps of analyzing the adjustable parameters of the corresponding power adjustable and modeling the power regulation characteristics include:

[0089] Model the power regulation characteristics of crushing, grinding and flotation equipment in the raw material preparation and pretreatment process, including:

[0090] The power of the crushing equipment is proportional to the width of the discharge opening, so its power characteristics can be expressed as:

[0091] P set1 ∝W set1 ;

[0092] In order to keep the crushing equipment in the best working condition, its power needs to be controlled within a certain range. In order to ensure the crushing efficiency and equipment life as well as the safe operation of the entire production line, the discharge opening width of the crushing equipment should meet the following constraints:

[0093] W set1min ≤W set1 ≤W set1max ;

[0094] Among them, Pset1 is the power of the crushing equipment, W set1 is the width of the discharge opening, W set1min and W set1max They represent the minimum and maximum values ​​of the width of the crushing equipment discharge opening under the production safety constraint;

[0095] The power consumed by the grinding equipment is proportional to its speed, and its power characteristics can be expressed as:

[0096] P set2 ∝v set2 ;

[0097] However, it should be noted that the speed adjustment should be carried out within the design range of the grinding equipment to avoid damage to the equipment. The speed should meet the following constraints:

[0098] v set2min ≤v set2 ≤v set2max ;

[0099] Among them, P set2 is the power of the grinding equipment, v set2 is the rotation speed of the grinding equipment, v set2min and v se t2 max They represent the minimum and maximum values ​​of the grinding equipment speed under the production safety constraints respectively;

[0100] The flotation machine equipped with a frequency converter can change the speed of the motor by changing the output frequency of its frequency converter, thereby adjusting its power. The power characteristics of the flotation equipment can be expressed as:

[0101] P set3 ∝f set3 ;

[0102] The subsequent stages of the electrolytic zinc load process rely on the raw materials provided by the pretreatment stage. Therefore, if the power of the flotation equipment in this stage is too low, too little zinc ore will be produced, which will have a greater impact on the subsequent production stages. Therefore, the frequency adjustment amount of the flotation equipment is subject to production safety constraints, as shown below:

[0103] f set3min ≤f set3 ≤f set3max ;

[0104] Among them, P set3 Indicates the power of the flotation equipment, f set3 is the output frequency of the flotation device, f set3min and f set3max They respectively represent the minimum and maximum values ​​of the inverter output frequency of the flotation equipment under the production safety constraints.

[0105] As a preferred implementation of this embodiment, the steps of analyzing the adjustable parameters of the corresponding power adjustable and modeling the power regulation characteristics include:

[0106] The power regulation characteristics of the stirring equipment and filtering equipment in the acid leaching process are modeled, where:

[0107] A mixer equipped with a frequency converter can change the speed of the motor by adjusting the output frequency of the frequency converter, thereby adjusting the power. Frequency conversion speed regulation has the advantages of a wide speed regulation range and high speed regulation accuracy. It can flexibly adjust the power according to different process requirements. The power characteristics of the mixing equipment can be expressed as:

[0108] P set4 ∝f set4 ;

[0109] To avoid equipment damage or poor production results due to over-adjustment, the output power adjustment of the inverter of the mixing equipment should be controlled within the production safety range:

[0110] f set4min ≤f set4 ≤f set4max ;

[0111] Among them, P set4 is the power of the stirring equipment, f set4 is the output frequency of the stirring device, f set4min and fset4max They respectively represent the minimum and maximum values ​​of the inverter output frequency of the mixing equipment under the production safety constraints;

[0112] The power consumption of the filtration equipment can be adjusted by adjusting the pressure of the filtration equipment to change its filtration speed, thereby achieving power adjustment. Its power regulation characteristics can be expressed as:

[0113] P set5 ∝F set5 ;

[0114] However, it should be noted that the filter cylinder pressure needs to be controlled within a safe range. Too high filter cylinder pressure will damage the filter bag and protective net. Therefore, the pressure of the filter equipment needs to meet the following constraints:

[0115] F set5min ≤F set5 ≤F set5max ;

[0116] Among them, P set5 is the power of the filtering equipment, F set5 is the pressure of the filtration equipment, F set5min and F set5max They respectively represent the minimum and maximum values ​​of the filter equipment pressure under the production safety constraints.

[0117] As a preferred implementation of this embodiment, the steps of analyzing the adjustable parameters of the corresponding power adjustable and modeling the power regulation characteristics include:

[0118] The power regulation characteristics of the electrolytic cell in the electrolysis process are modeled, and the electrolytic cell is equivalent to a resistor and back electromotive force. The equivalent circuit diagram is attached. Figure 2 As shown. The power consumption of the electrolyzer is related to the magnitude of the DC side current, and the power coupling characteristics are as follows:

[0119]

[0120]

[0121] Among them, P set6 is the power of the electrolytic cell, U B is the voltage of the electrolytic cell, I d is the current of the electrolytic cell, R is the equivalent resistance of the electrolytic cell, E is the back electromotive force of the electrolytic cell, U CH is the bus voltage on the high-voltage side of the load, U CL is the bus voltage on the low-voltage side of the load, k is the transformation ratio of the step-down transformer in the electrolytic zinc plant, U SR is the voltage drop of the saturated reactor; when adjusting the power of the electrolytic zinc load, the equivalent resistance R and back electromotive force E of the electrolytic cell and the bus voltage U on the high-voltage side of the load can be CHAs a constant, the saturated reactor voltage drop U SR To change the current I through the electrolytic cell d Thereby changing the power consumption P of the electrolytic cell set6 ;

[0122] The electrolytic process of electrolytic zinc requires that the electrolyte in the electrolytic cell be maintained within a certain temperature range. If the temperature is too high, the equipment may be damaged, and if the temperature is too low, the success rate of the electrolytic reaction will be affected. Therefore, when adjusting the voltage drop of the saturated reactor, production safety constraints must also be met:

[0123] U SRmin ≤U SR ≤U SRmax ;

[0124] Among them, U SRmin and U SRmax They respectively represent the minimum and maximum voltages to which the saturated reactor can be adjusted while satisfying production safety constraints.

[0125] The above power-adjustable equipment can complete the adjustment on a time scale of seconds, and involves multiple key process flows such as raw material pretreatment, acid leaching treatment, and electrolysis. Therefore, the above electrolytic zinc load power control model has great reference significance for high-energy-consuming industrial loads.
