Power intelligent control management system and power service integration solution

◆ Line loss
When a user enterprise is building a new project, in order to pursue the timeliness of production, it is often easy to ignore the cost-effectiveness of the high-voltage substation and distribution line construction, and it will blindly pursue the start of construction. As long as it can meet the general production needs, it will be used. Hidden dangers are buried in the safe use of the equipment. The normal range of the line loss value is: line loss value ≤5%. The SL-ZPL-1000 electric energy saving intelligent control management system collects loop measurement data online, calculates it through the background, and compares. Generate reports and store them in the cloud server at the same time, promptly remind users to check through the mobile phone, and at the same time find problems, solve problems, and ensure that enterprises use electricity and save energy.
◆ Causes of Line Loss
The line loss is generally caused by the following reasons: the transmission line is old and the wire diameter is too small to meet the maximum requirements for voltage and current to pass; the production load of the enterprise has soared, and the original wire load was too large.
◆ Consequences of Line Loss
The most direct loss caused by excessive line loss is the increase in the cost of electricity used by the company, the huge increase in electricity costs, and severe line loss will accelerate the life of the wire and drastically reduce the cost of the company. It will even cause a fire and burn the electrical equipment. Production interruption caused huge economic losses.

◆ Power factor
In the process of using electricity, user companies often have low power factor due to the seasonality of production, the time difference when the load is turned on, or even the mismatch of the load. The normal range of power factor value is: cos∮≥0.9.
◆ Consequences of low power factor
● Power supply department fines
● The line loss of the power network has increased significantly, and the output capacity of electrical equipment has decreased, resulting in abnormal production.
● Increase in electricity expenses

◆ Transformer over-temperature does not match transformer load
The user company had problems when designing the transformer capacity at the beginning, or problems caused by adjusting the load after the production volume increased.
◆ Results of mismatch between transformer overtemperature and transformer load
● Big Mara trolley will increase its damage and decrease its power factor.
● Small horse-drawn carts will increase the damage and reduce the life of the transformer. If the temperature exceeds the upper limit of 10 degrees, the life will be reduced by half.
● Electricity costs of enterprises increase, and production is not safe.
◆ Transformer over-temperature and transformer load mismatch solution
SL-ZPL-1000 power energy saving intelligent control management system will find out that the transformer over-temperature and the transformer load do not match during the self-inspection process, it will remind the user company to reduce the basic electricity cost by expanding or reducing the transformer, and ensure the most Optimal economic operation interval, maximize efficiency, and eliminate potential safety hazards.
◆ Three-phase unbalance
Due to improper electrician operation and unscientific wiring of electrical equipment, the user company's load on one phase is too large, and the load on each phase (air conditioner, water heater, computer lighting, etc.) is unbalanced, and three-phase imbalance will occur.
◆ Three-phase unbalanced consequences
● The output power of electrical equipment such as three-phase motors decreases, the motor overheats, the transformer working capacity decreases, and there is a large amount of neutral current in the circuit.
● A large amount of wire loss is caused, and the switch is easy to burn.
● Increase in electricity expenses
◆ Three-phase unbalanced solution

Through background modeling and analysis, it promptly reminded the user company, issued an early warning signal, let the company adjust, and provided energy saving Based on this, at the same time avoid electrical fires caused by three-phase imbalance, ensure the normal use of electrical equipment, and escort the safe and continuous production of enterprises.
◆ Serious harmonics <br /> In the production process, users use a lot of equipment (computers, inverters, electric arc furnaces, UPS power supplies) that change the common frequency, or the power is too large, causing a lot of harmonics.
◆ Harmonic consequences
● Capacitor equipment is overheated and burned, and the terminal is accelerated to oxidize, resulting in poor contact.
● The meter reading is inaccurate, and the relay malfunctions.
● Reduce power factor, increase line loss, change loss, etc.
● Electrical equipment is too noisy, vibration, electromagnetic pollution.

◆ Unscientific or missing electricity management
The user company does not have an automatic monitoring system or an electrician. At the same time, it is unscientific in power management. There is even “running, running, leaking, dripping” or stealing electricity or human waste.
◆ Consequences:
● The motor is idling (up to 60% -70% reactive power consumption). The transformer is no-load or too low load (reactive power is 3 times of full load).
● Each household's electricity monitoring in the living area, the school monitors the electricity consumption of the student dormitory.
● Electricity expenses increased.
● Pay more for electricity and increase production costs.
◆ Unscientific electricity management or missing solutions
