Description

Technical Field

[0001] The present invention belongs to the field of electrical automation, and in particular relates to an adjustable load verification method and system for a large commercial complex. Background Art

[0002] With the development of economy and technology and the improvement of people's living standards, electricity has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, ensuring the stable and reliable supply of electricity has become one of the most important tasks of the power system.

[0003] In the real-time operation and control process of the power system, adjustable load is an important part of the power system. Due to the uncertainty of the power system load, adjustable load has become an important means of regulation of the power system. At present, the power system generally requires that the proportion of adjustable load is 5% of the maximum load of the power grid.

[0004] In response to the above requirements, the power system needs to conduct detailed investigation and verification of the adjustable load during normal operation to ensure that the adjustable load reaches the requirement of 5% of the maximum load of the power grid. However, the current verification method for adjustable loads still relies on the data entry of theoretical values ​​in advance; this is undoubtedly inconsistent with the precise control requirements of today's power grid. At the same time, the capacity of the adjustable load is heavily dependent on theoretical data. The inaccuracy of the theoretical data may cause the power grid to have insufficient adjustable load capacity when performing load adjustment, which will seriously affect the safe and stable operation of the power grid. Summary of the invention

[0005] One of the purposes of the present invention is to provide an adjustable load verification method for a large commercial complex that is highly reliable, practical, accurate and stable.

[0016] The preliminary verification of the load data obtained in step S1 described in step S2 specifically includes the following steps:

[0018] If the load data is directly obtained from a large commercial complex to be verified, the load data is pre-checked using the following rules:

[0062] S1. Obtain the load data of the large commercial complex to be verified from the power grid; specifically, the steps include:

[0063] If the database of the power grid contains the adjustable load data of the large commercial complex to be verified, the adjustable load data of the large commercial complex to be verified is directly obtained from the database of the power grid;

[0066] If the load data is the adjustable resource data of a large commercial complex to be verified obtained from the power grid’s database, no preliminary verification is performed;

[0067] If the load data is directly obtained from a large commercial complex to be verified, the load data is pre-checked using the following rules:

[0072] R1. If the user response capacity is greater than the user maximum load, the verification fails;

[0073] R2. If the user response capacity is greater than the user's maximum capacity, the verification fails;

[0074] R3. If the device response capacity is greater than the device rated power, the verification fails;

[0075] R4. If the device verification fails under the user, the user verification fails;

[0076] R5. If the user response capacity is not equal to the sum of the response capacities of all devices under the user, the verification fails;

[0077] S4. Verify the industry rules for the proofread data obtained in step S2; specifically, the following steps are included:

[0078] a. Obtain user information of the large commercial complex to be verified: User information includes central air conditioning system load and VRV air conditioning adjustable load;

[0079] The annual energy consumption peak of large commercial complexes is mainly concentrated in the summer, generally from June to September, with air conditioning load accounting for the largest proportion, which can reach more than 50%. Its lighting load is relatively stable, usually accounting for about 20%. The power load mainly comes from elevators, water pumps, etc., with a load share of about 15%, and the cold storage refrigeration load is about 10%. The public area of ​​the commercial complex is the main controllable area, and the controllable equipment is generally air conditioning equipment, lighting equipment, kitchen cold storage, etc.;

[0080] b. If the user information of a large commercial complex to be verified is the central air-conditioning system load, the following formula is used to determine the user's adjustable load capacity ΔP:

[0081] ΔP=ΔP t +ΔP a +ΔP w +ΔP v +ΔP f +ΔP c +ΔP d

[0082] Where:

[0083] Global Temperature Control:

[0084] Control mode: change operating parameters; Control object: central air conditioning system;

[0085] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 1-2h;

[0086] By increasing the indoor set temperature value of the terminal equipment control panel, the indoor temperature rises, resulting in an increase in the water temperature of the chilled water circulation system, an increase in the evaporation temperature of the chiller, a reduction in the work of the unit compressor, and a reduction in the unit power consumption. For every 1 degree Celsius adjustment in temperature, the electrical load changes by 7%; therefore, ΔP t is the global temperature control load capacity, and ΔP t =7%×P air ×ΔT,P air is the system power sum of all air conditioners in the large commercial complex to be verified, ΔT is the temperature adjustment;

[0087] Pre-cooling control:

[0088] Control mode: change the operation mode; Control object: chiller;

[0089] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 0.5-1h;

[0090] Increase the number of chillers started one hour or half an hour in advance by remote or local means, increase the cooling capacity of the chillers, and reserve cooling capacity in advance to ensure comfort and reduce the number of chillers started during response; therefore, ΔP a is the pre-cooling control load capacity, and ΔP a =δ1P m1 +P a , δ1 is the correction value, P m1 is the host operating power, P a Provides operating power for auxiliary equipment;

[0091] Adjusting the chilled water temperature:

[0092] Control mode: change operating parameters; Control object: chiller;

[0093] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 1-2h;

[0094] By increasing the chilled water temperature in the chiller control panel through remote or local control, the evaporation temperature of the unit is increased. By increasing the evaporation temperature, the external work of the unit compressor is reduced, and the power consumption of the unit is reduced; therefore, ΔP w To adjust the chilled water temperature load capacity, and ΔP w =ΔT'×δ2×P m , ΔT' is the temperature adjustment value, δ2 is the correction value, P m is the operating power of the centrifugal unit;

[0095] Restricting cold water valves:

[0096] Control mode: change operating parameters; Control object: chiller;

[0097] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 0.5-2h;

[0098] By adjusting the opening of the chilled water pipe supply valve in the indoor air supply device, the chilled water flow is reduced, resulting in a decrease in the chilled water flow on the evaporator side of the refrigeration unit, which reduces the work of the chiller compressor and reduces the power consumption of the chiller; therefore, ΔP v To limit the cold water valve load capacity, and V a To adjust the water flow, V r is the operating water flow, δ3 is the correction value, P m is the operating power of the centrifugal unit;

[0099] Fan / refrigeration (or cooling)-water pump / cooling tower frequency conversion control:

[0100] Control mode: change operating parameters; control object: fan / refrigeration (or cooling)-water pump / cooling tower;

[0101] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 0.5-1h;

[0102] By changing the motor output frequency, the motor power is reduced. By automatically or manually changing the motor frequency setting value of the fan / refrigeration (or cooling)-water pump / cooling tower equipment, the motor speed of the air supply equipment is reduced, the air supply of the air supply equipment is reduced, and the power consumption of the motor is reduced; therefore, ΔP fThe load capacity of the fan / refrigeration-water pump / cooling tower variable frequency control, and ΔP f =∑(1-(f1-f) 3 )×P b +δ4×P m , f1 is the limited frequency, f is the reference frequency, P b is the base load of the fan / refrigeration-water pump / cooling tower, δ4 is the correction value, P m is the operating power of the centrifugal unit;

[0103] Limiting cooling demand:

[0104] Control mode: change operating parameters; Control object: chiller;

[0105] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 0.5-1h;

[0106] By remote or local means, the percentage setting value of the rated current of the chiller is reduced to reduce the work done by the chiller compressor and reduce the power consumption of the unit; therefore, ΔP c To limit the cooling load capacity, and δ5 is the correction value, N1 is the host limit load value, N r Output value for host operation, P m is the operating power of the centrifugal unit;

[0107] Adjust the number of fans / cooling towers:

[0108] Control mode: change the operation mode; Control object: fan / cooling tower;

[0109] Control mode: direct control (rigid); Adjustment time: minutes; Response time: 0.5-1h;

[0110] By shutting down some fans / cooling towers, the number of fans / cooling towers in operation is reduced; therefore, ΔP d To adjust the fan / cooling tower load capacity, and ΔP d =n×P d +δ6×P m , n is the number of fans / cooling towers to be reduced, P d is the power of a single fan / cooling tower, δ6 is the correction value, P m is the operating power of the centrifugal unit;

[0111] b. If the user information of a large commercial complex to be verified is the VRV air conditioning adjustable load, the following formula is used to determine the adjustable load of each device in turn:

[0112] For temperature-regulated devices:

[0113] Control mode: direct control (flexible); Adjustment time: seconds; Response time: 1-2h;

[0114] When the temperature is adjusted by the remote control, the electrical load changes by 7% for every 1 degree Celsius adjustment of the air conditioner temperature;

[0115] Therefore, the following formula is used to determine the temperature control load capacity ΔP t1 :

[0116] ΔP t1 =7%×P air1 ×ΔT

[0117] Where P air1 is the system power sum of all temperature regulating devices, ΔT is the temperature adjustment;

[0118] For frequency regulated devices:

[0119] Control mode: direct control (flexible); Adjustment time: minutes; Response time: 0.5-1h;

[0120] Adjust the load by adjusting the compressor motor frequency;

[0121] Therefore, the following formula is used to determine the frequency control load capacity ΔP i1 :

[0122]

[0123] Where N i1 is the frequency conversion, N e1 is the rated frequency, P e1 is the rated load;

[0124] For decentralized air conditioning:

[0125] If the air conditioner is temperature controlled:

[0126] Control mode: direct control (flexible); Adjustment time: seconds; Response time: 0.5-2h;

[0127] The air conditioner temperature is adjusted by the remote control. For every 1 degree Celsius adjustment of the air conditioner temperature, the electrical load changes by 7%. Therefore, the following formula is used to determine the distributed air conditioner temperature adjustment load capacity.

[0128] ΔP t2 =7%×P air2 ×ΔT

[0129] Where P air2 is the system power and temperature control equipment of all decentralized air conditioners, ΔT is the temperature adjustment amount;

[0130] If the air conditioner is controlled by on / off:

[0131] Control mode: direct control (rigid); Adjustment time: seconds; Response time: 0.5-1h;

[0132] Turn off / on the air conditioner for a short period of time without affecting the user's comfort;

[0133] Therefore, the following formula is used to determine the load capacity ΔP1 of the decentralized air conditioner on / off control:

[0134]

[0135] Where m is the number of devices; P i1 The air conditioning power adjusted by the decentralized air conditioning on / off control, and if the air conditioning is turned off, P i1 =0, otherwise P i1 is the rated power of the air conditioner;

[0136] For lighting equipment:

[0137] Control mode: direct control (rigidity); Adjustment time: seconds; Response time: 0.5-2h;

[0138] According to different lighting needs of users, lighting load can be divided into uncontrollable necessary lighting and controllable unnecessary lighting. In order to ensure normal work and production of users, the method of split area control is generally adopted to turn off some lighting equipment to achieve the purpose of reducing lighting load.

[0139] Therefore, the following formula is used to determine the lighting equipment regulation load capacity ΔP decreased :

[0140] ΔP decreased =P lighting

[0141] Where P lighting The total power consumption of the lighting equipment that is turned off;

[0142] For cold storage:

[0143] Control mode: direct control (rigid); Adjustment time: seconds; Response time: 0.5-1h;

[0144] While ensuring the temperature of the cooled objects, the start-stop control is used to optimize the power consumption of the cold storage;

[0145] Therefore, the following formula is used to determine the cold storage equipment adjustment load capacity ΔP2:

[0146]

[0147] Where m2 is the number of devices; P i2 is the power of the cold storage, and if the cold storage is turned on, Pi2 =0, otherwise P i2 is the rated power of the air conditioner;

[0148] S5. Output the verification results obtained in step S3 and step S4 to complete the verification of the adjustable load of the large commercial complex.
