Recently residents of Shanghai and other places exposed the installation of smart meters after the electricity bill soared, questioning the quality of electricity meters and power companies from doing a good job. In fact, this phenomenon has long been antecedent in countries such as Britain and the US: Installing a smart meter does not necessarily mean a drop in electricity bills. It does not have the intelligence to be able to actively save electricity. At the current stage, it is just an optimization of people's electricity habits. Tools, and the full use of knowledge in order to ensure the success of the promotion of smart meters, the Chinese power companies lack common sense of use, but simple and ruthless "a peace of mind", but it should be energy-efficient smart meters as electricity developers.
First, the smart meter should be a good thing Compared with the old-fashioned meter, smart meter has a high measurement accuracy, smart deduction, electricity prices real-time query, power memory, meter reading time freeze, balance alarm, remote transmission of information and other features, can be maximized Avoid human errors and effectively prevent electricity theft.
Smart meter is the development direction of future smart grid terminal Smart meter is actually a metering device launched to realize the national smart grid, and is an important part of the system construction. The so-called smart grid is the intelligence of the grid, also known as "grid 2.0." It is based on an integrated, high-speed two-way communication network. It uses advanced sensing and measurement technologies to achieve the goals of safe, reliable and cost-effective power grids, and is characterized by information, digitization, automation, and interaction. The construction of “electricity information acquisition system†is the basis for achieving full collection of energy information, full coverage, and full prepayment. It is an important part of the construction of a smart grid, and eliminates the misuse and misuse of electricity in the original manual transcription. Missing copying and meter reading are not timely and other issues.
Smart meter is good: you can check the power at any time. The benefits of smart meters are many in publicity: This new type of smart meter allows power users not to go outside to find the meter to check the power, but can directly check the electricity bill, alarm, and history through the LCD display on the meter. With electricity, real-time electricity prices and power supply curves, and other information, to understand their own power usage at different times, turn off certain electrical appliances when the peak of electricity is used, set electricity consumption plans according to their own needs, and save electricity during budgeting. It can also automatically read the meter remotely by the computer, which will greatly improve the accuracy and work efficiency of meter reading, effectively avoid the error of manual meter reading, and can remotely analyze the meter data, help the power supply company to grasp the customer power consumption information, and obtain the on-site failure at the first time. And abnormal conditions, convenient and timely repair, reduce power outage time.
Second, why smart meter is not intelligent In theory, smart meters can really reduce people's power expenses, so that electricity consumption is more reasonable. However, due to the occasional technical defects of the meter, people lack the common sense of using smart meters in most cases, and the lack of service to consumers by the power companies, many consumers are overwhelmed with smart meters. Since mid-February, netizens in Shanghai and other places have repeatedly stated that the replacement of smart meters has led to a doubling of electricity charges. Behind the surge in electricity bills, there is a shadow of the replacement of smart meters, which is also an issue that cannot be avoided when smart meters are promoted abroad.
The United States has received a large number of complaints: smart meters so that the electricity bill soared The "New York Times" has reported that an American Army soldier came home after serving, found that since the installation of a smart meter, the cost of electricity in January higher than a month. Although he has already saved electricity, he still believes that the electricity bill is still rising. He believes that the smart meter has exploited it as "perfect." The issue of "increase in electricity bills for smart meters" has triggered the nationwide discussion in the United States. In 2010, major U.S. power companies installed approximately 2 million smart meters in the United States. Since then, the nightmares of the major power companies have begun. Various complaints have flooded into the country. In some states, workers have even received class actions from the masses. The main content of the complaint is "The new meter increases the power consumption." In 2009, in order to modernize the U.S. power grid, the Obama administration took out 3.4 billion U.S. dollars from federal stimulus funds, and part of the expenditure was spent on installing smart meters. However, it did not expect the outcome to be the case.
Meter quality: no quality problems and no "dirty"
After the installation of smart meters in China caused a surge in residential electricity consumption that caused the electricity tariff to double, the electricity company’s examination of the electricity meter in response to questions from the public indicated that most electric meters did not have quality problems. However, for the reason why smart meters do not save power, U.S. power companies gave an investigation and analysis: The U.S. federal government ordered an independent consulting firm to conduct a thorough investigation. In September 2010, an analysis report released by the company pointed out: In most cases, the accuracy of smart meters is not a problem, which is consistent with the power company's statement. In the analysis of the complaints one by one, it was found that most of the complaints were caused by heat wave transits, changes in personal habits, or the fact that old electricity meters were aging and the electricity bills were too low. At the same time, the report pointed out that the power companies have done extremely poorly in directing consumers to use smart meters and solve consumer distress.
Energy efficiency is ineffective: meter intelligence only stays “more sensitive†The intelligence of China's current smart meters only stays at an initial stage, and the reason for the increase in electricity bills is that it is more sensitive and any small current will make the meter turn. Previously, the traditional meter used in China was usually an “inductive meter†with a disk rotating with the power consumption. The disc was supported by the bearing. As time goes by, the bearing gradually ages and friction increases, and the rotation speed slows. Previously, the cost paid was less than the actual use of electricity. Since the smart meter can accurately measure the power consumption, the result is that “electricity fees have risen.†On the other hand, smart meters currently cannot actively help save household electricity. It is more like using a precise method to remind consumers to pay attention to the consumption of electricity at any time. Therefore, not only electricity meters but also people's electricity habits are replaced. A change in the electric power company's work in this regard is not optimistic, resulting in the residents' misunderstandings of this kind of meter, and did not play a "energy saving" role.
Third, smart meter how to save electricity smart meter and smart grid combination, in theory, is indeed an effective way to save energy: Analysis of a non-profit electrical institute in California predicts that if you can really use smart meters to build a nationwide intelligence The electricity grid, by 2030, will reduce electricity consumption throughout the United States by more than 4%, which means that it will save consumers and electricity companies $20.4 billion — but these forecasts must be based on the universal acceptance of smart metering by consumers. basically.
The time difference between smart electricity meters with good electricity consumption can more accurately distinguish the time span of household electricity consumption. Today, when the ladder electricity price is implemented, the price of electricity during peak hours is more than double the price of electricity during leisure hours. Since the smart meter can display the power consumption of households in the meter, residents can make good use of the “peaks and valleys†period of electricity consumption, reduce the amount of electricity during the peak period of electricity consumption, and put some of the use of electrical equipment at the bottom. For example, at the peak time (8 am to 10 pm), the electricity price is 6 cents/degree, and at the bottom of the grid, the electricity price is 3 to 1, and residents can calculate that “afternoon pot soup is more expensive than washing clothes at nightâ€. The reality, all the electricity that is unrelated to time, wait until late at night and weekends, this includes all the activities related to laundry ironing, most of the baking, some soup stew and so on.
Electricity meter urges to develop power-saving habits As mentioned earlier, smart meters are more sensitive than conventional meters, and any subtle electric currents are recorded. The Chinese family did not pay attention to some details about the use of electricity. For example, after turning off the TV or computer, the power switch on the screen is still on, or the computer is in the standby state, and various chargers are still plugged in to the power supply. Although the amount is small, it will also be recorded, not to mention that many Chinese families are not used to cutting off the power of small appliances, so the accumulated power is not small. Once there was a family in Canada that had caused an increase in electricity consumption due to the use of smart meters, it had bought an instrument to measure the amount of electricity used by various appliances. As a result, one day's follow-up discovered that an ordinary electric kettle is a large consumer of electricity. Therefore, letting more people use “smart†power is the function of smart meters, otherwise electricity bills will only soar.
The power company should use scientific knowledge from a science institute of a non-profit organization in California and predict that if it can really use a smart meter to build a smart grid that covers the entire United States, the electricity consumption of the entire US will be reduced by more than 4% by 2030. This also means that It can save consumers and power companies $20.4 billion. However, these predictions must be based on consumers' full acceptance of smart metering. The reality in China is that the installation of a smart meter is only a power outage notice issued by the power company. It does not provide in-depth guidance on how to use the smart meter to achieve the purpose of energy conservation. It is also difficult to escape the question of electricity charges.
Conclusion: The smart meter is not an energy-saving tool that can be used effectively. It plays a role in the current stage to make people change their habit of using electricity and optimize the way of using electricity. China's electric power companies have simply and crudely installed and not universally used the guideline, which inevitably leads to smart electric meters becoming image engineering and gold mining tools.
