Information

According to a survey, more than 90 percent of the business owners or the financial personnel in the enterprises who are responsible for paying electricity bills have never paid any attention to the specific contents on the electricity bill, but only pay the electricity fee just in the amount which is indicated on the electricity bill. However, on an electricity bill of a small amount, a fact has been hidden, which the owners of the enterprise can not be ignored!

In the electricity bill of an industrial enterprise, there will be a column of "Fee of adjusted electricity" (some places are called "adjusted electricity fee", and this is different from place to place). This is a kind of penalty which is charged by power supply company in the case that the power factor of the enterprise does not meet the specified standard in the process of using electricity! It will be possible for an enterprise to avoid this kind of penalty through improvement, transformation and upgrading of the reactive power capacitor compensation cabinet in its own distribution room!

The fee of adjusted electricity refers to the fact that the power supply company calculates the average power factor according to the active power and the reactive power which have been used by the customer for a period of time (such as one month or one year), and charged the related electricity fee accordingly.

Suppose an enterprise consumes 1.2 million kWh of electricity a year. The reactive power compensation power factor of the enterprise is 0.84 yuan per kWh, the monthly electricity charge is 80000 yuan, according to the charging standard of the power supply company, the power factor is 0.84, the adjusted electricity coefficient is 3%, the monthly fee of adjusted electricity will be 80000*3%=2400 yuan. The penalty for the reactive power in one year will be 2400*12=288002400 yuan. Perhaps some people may say, the fee of adjusted electricity is only more than 20,000, it doesn't matter. However, if the power consumption of the enterprise reaches 2 million kWh, 5 million kWh, 10 million kWh, 50 million kWh, and If the power factor is lower, it will be possible to have an idea about how much is the amount of the fee of adjusted electricity.

The electricity bill adjusted with the power factor which uses 0.90 as its standard value
Power factor	The electricity charge is decreased (%)	Power factor	The electricity charge is increased (%)	Power factor	The electricity charge is increased (%)
100	0.75	0.89	0.5	0.76	7
99	0.75	0.88	1	0.75	7.5
98	0.75	0.87	1.5	0.74	8
97	0.75	0.86	2	0.73	8.5
96	0.75	0.85	2.5	0.72	9
95	0.75	0.84	3	0.71	9.5
94	-0.6	0.83	3.5	0.7	10
93	-0.45	0.82	4	0.69	11
92	-0.3	0.81	4.5	0.68	12
91	-0.15	0.8	5	0.67	13
90	0	0.79	5.5	0.66	14
		0.78	6	0.65	15
		0.77	6.5	0.64	17
With regard to the power factor with a value from 0.64 and below, the electricity bill is increased by 2% for every reduction of 0.01 in the power factor.

So those business owners may have have a question to ask, what is the cause of the "fee of adjusted electricity "? The writer summed up the reasons according to the information of the customer obtained from the websites and telephone consultations. The reasons can be basically divided into the following categories:

1. No reactive power capacitor compensation cabinet has been provided: The industrial enterprise has the distribution room which is under its own management. For some business owners, in order to save costs, their distribution room is not equipped with the reactive power capacitor compensation cabinet.

2. The reactive power capacitor compensation cabinet has the problem of overcompensation or undercompensation: In the distribution room of some enterprises, the reactive power capacitor compensation cabinet has been provided. However there will also be the electricity fee penalties. This is because, at the beginning of the design, the power design institute did not take into account the increase and decrease in the number of the electricity consuming equipment in the later stage of the enterprise. So the corresponding capacity of the reactive power capacitor compensation cabinet is too large or too small, and the accuracy of the compensation control system is low, and so on.

3. The technical faults with the reactive power capacitor compensation cabinet: The enterprise has failed to slect the correct switching mode of the reactive power capacitor compensation cabinet according to the situation of the electricity consuming equipment of the enterprise; the capacity of the reactive power capacitor compensation cabinet is graded in a rough manner; the power factor is not up to standard due to factors such as the voltage and current harmonic, reactive compensation sensitivity, etc are not considered. Therefore the fee of adjusted electricity has occurred.

There are so many problems in the distribution room of the enterprise, then what are the solutions for them?

The main work for the enterprise to do is to looks for professionals to check the actual electricity consumption data of the enterprise, and formulate the relevant scheme for transformation and upgrading of the reactive power capacitor compensation cabinet on the basis of their own actual production situation.

DELITER will create a dedicated scheme of the reactive power capacitor compensation cabinet for the enterprises on the basis of their own conditions. In this way the power factor will be improved and the power quality will be optimized, cand your problem with the electricity fee penalty will be completely solved!

Why should reactive power compensation be carried out? What is the principle and form of reactive power compensation?

1、 Why should reactive power compensation be carried out? Reactive power is by no means useless power. In the AC power supply system, inductance and capacitance are essential loads, such as ferromagnetic loads such as motors and transformers. If there is no excitation of inductive reactive power, the equipment cannot work normally. For example, the line itself that transmits power at a fixed distance is a capacitive load. As long as it is transmitting power, it will be equivalent to the capacitor working. In other words, in the AC power supply system, the existence of reactive power is of great significance to the transmission and exchange of energy, which is indispensable, or the exchange system without reactive power can not work normally.
