Keywords:four quadrant, energy saving, green and environmental protection, safe and comfortable

1. Preface

A building in Wuxi City adopts six elevator group control with high elevator usage frequency and frequent braking, the original inverter brake adopts the energy dissipation resistance with huge heat and energy consumption. In order to reduce energy consumption, now we conduct the energy-saving transformation to a lift, the original system will be replaced by EC300 four quadrant whole machine to achieve energy-saving effect.

2. Configuration and description before the transformation:
Elevator load 1350KG, speed 2.5m / s motor power 23.2KW, frequency power table 30KW, 30 layers 30 stations
The original system is the elevator controller + inverter + brake resistor
The usage place is an office building.

We all know that most of the elevators used in our country are traction elevators, the elevator car is on the one side and the balanced counterpoise is on the another side of the elevator. When the elevator is descending (or rising), braking is needed to keep the uniform or decelerate running. In the process, a large number of mechanical energy is changed into electrical energy via the motor, and it consumes the power in the form of heat energy via the brake resistor, resulting in a serious waste. The brake resistor emits heat and has a certain impact on the machine room temperature, it often needs to install air conditioning and ventilation equipment for the heat dissipation, which has increased more extra cost, following is the illustration of braking state.

Figure 2.1 the total weight of elevator car and people is less than the elevator counterpoise

Figure 2.2 the total weight of elevator car and people is more than the elevator counterpoise

Figure 2.3 The host and control cabinet before the transformation.

3. Energy saving transformation program
The original system is all replaced by 30KW EC300 four quadrant intelligent whole machine, in the braking state of elevator, the power generated by motor is feedbacked to the power grid via the EC300 four quadrant feedback technology to achieve the purpose of energy saving, meanwhile the system external reactor, the feedback current harmonic<5%, to meet the green standards. As shown below:

Figure 3.1 the total weight of elevator car and people is less than the elevator counterpoise.

Figure 3.2 the total weight of elevator car and people is more than the elevator counterpoise.

Figure 3.3 The control cabinet after the transformation.

4. Feedback principle of EC300 four quadrant intelligent whole machine.

Inverting and rectification design principle of EC300 four quadrant intelligent whole machine EC300 rectifier part is IGBT six pulse control rectifier,in the electric state, after the bus is lifted to a certain degree, the energycan be feedbacked to the power grid to achieve the purpose of energy saving.

5. Energy - saving test methods and energy - saving ratestatistics
5.1 Adopted test equipment
1 set StandardelSDT871 bi - directional meter
5.2 Energy-saving rate calculation method
Energy-saving rate calculation method: power generation /(power consumption + power generation) * 100%
As shown in the following table on May 23, the measuredrate is calculated as follows:
The current cumulative generating capacity is 175.8
The current cumulative power consumption is 319.3
Saving rate:energy-saving rate calculation method: power generation / (power consumption +power generation) * 100% = 175.8 / (175.8 + 319.3) * 100% = 35.5%
5.3 Energy saving statistics

Statistical date	Parameter statistics
April 27th	power consumption	Power generation	Power saving rate of motor
April 28th	17.6	9.3	34.5%
May 9th	72.8	38.7	34.7%
May 23rd	319.3	175.8	35.5%

The elevator is put into use from April 28, 2016, the data statistics to May 23, we can see from the above data, the power generated by the motor after the usage of INVT EC300 products, the energy-saving rate can up to 35%.

The user of energy-saving electricity: the owners public lighting, fans, air conditioning, water pumps and other equipment, so the whole system is energy saving, that is in the same conditions, adopting four quadrant products can save more than 30% electricity per month for the owners. The energy saving is more pronounced in the following case

a.the higher floor the elevator is, the more frequent braking , the more energy saving;

b.the new installation of the elevator, the larger mechanical inertia, the more energy saving;

c.the longer the elevator is used, the greater friction is, the more energy saving;

d.the faster the elevator is, the more frequency brake, the more energy saving;

e.the more frequent the elevator is used, the more frequent brake, the more energy saving.

f.product highlights of EC300 four quadrant intelligent whole machine

1.More efficient energy saving

The driver uses the six-pulse controllable rectifier, which has the power supply feedback function. When the elevator control system is in the power generation state, the regenerative energy is fed back to the power grid via the energy feedback technology (without braking resistance, the braking heat loss is converted into electrical energy).

To achieve the purpose of energy conservation, power saving rate up to 30%, energy saving efficiency is relative to the elevator power, the whole elevator system, the elevator balance system and other aspects, the energy efficiency is better in the following circumstances.
