Today I will talk about the measurement of industrial electricity. Many friends have asked this question in order to answer their questions. Speaking of measurement, I have to first introduce the principles of China's industrial electricity measurement methods. First of all, let’s talk about the electricity price of one-part system. The so-called price of one-part system means that there is a part of the electricity price, that is, the active electricity price, which means that you pay for how much electricity you use, regardless of time and capacity. The price remains unchanged, and the power supply bureau determines how much electricity is once. Let’s talk about the two-step electricity price. As the name suggests, electricity prices are composed of two parts. One is the active electricity price, which is the electricity used by your equipment, and the other is the capacity price, which is the capacity price of the transformer. Similar to Jiangsu, for example, one kilovolt-ampere charges 30 yuan, for example, a 315 transformer charges a monthly basic electricity bill of 9,450 yuan. Two-step electricity price, utility electricity price, divided into four electricity price gradients: peak, peak, flat, and valley. In different electricity time periods, electricity prices are different. According to their own conditions, the time periods are similar. Let's talk about the tips separately. The price of electricity, and the start of the peak electricity price is determined according to the local temperature. The specific conditions vary slightly from place to place. Finally, I would like to talk about the problem of overcapacity fines for transformers. Netizens have many questions about this issue. Speaking of over-capacity fines, first explain what is the maximum monthly demand, transformer terminal control equipment, and the distribution room of each transformer has this device. It communicates with the relevant departments of the Electric Power Bureau. Demand is useful work. That is, the control terminal collects the total power at this moment every 15 minutes, as the demand at this moment, and compares the demand values collected every 15 minutes in the month. The largest demand value is the monthly maximum demand. .
The Power Supply Bureau stipulates that the transformer capacity cannot exceed 15% of the transformer capacity. If it exceeds 15% of the transformer capacity, it will be fined. The fines vary slightly from place to place. A friend asked, the workshop cable was short-circuited, and the large current at the moment was just collected by the control terminal. The monthly maximum demand value is quite large. Will it face a fine for overcapacity? The power supply bureau can also consider this problem. The measures taken by different regions are different. For example, in Jiangsu, multiple point values are collected every 15 minutes, and then these multiple point values are averaged to calculate the average value. Demand value collected in 15 minutes. On the Henan side, if your transformer exceeds the capacity and exceeds the 15% of the specified value, the terminal will start to count the time. Add all the time of the transformer overcapacity within this month. If it exceeds 1 hour, it will be overcapacity. Fines, not exceeding 1 hour, are not considered excessive, no fines. There is also a charging method, which is based on demand. If your transformer is 500 kVA, but you have less electrical equipment, you can only use 200 kilowatts on weekdays. If you pay the basic electricity bill based on capacity , You have to pay a basic electricity bill of 15,000 yuan per month. If you calculate it, your electricity price per kilowatt-hour may be higher. To avoid this, you can apply for payment on demand and apply for a transformer capacity of 250 kVA. In this way, the basic electricity bill every month is much less. However, after you apply for payment on demand, you cannot exceed your application demand value, otherwise you will be fined. Application demand payment is divided into contract demand and non-contract demand. Contract demand cannot exceed your application demand. The non-contract demand can exceed the demand value you apply for, and the unit price of the basic electricity fee based on the demand is slightly higher than the basic electricity fee for the capacity. In Jiangsu, 30 yuan/kVA based on capacity and 40 yuan/kVA based on demand.
