Introduction To Line Fittings What Is Statistical Line Loss?

Introduction to Line Fittings What is statistical line loss?

Statistical line loss is calculated based on the reading of the energy meter, that is, the difference between the power supply and the power sales. This calculation method is called the residual method in statistics. Its accuracy depends on the accuracy of the metering system for measuring the power supply and the power sales, as well as the scientific and reasonable transcription and statistical system for the customer's power sales.

Fuse Link What are the calculation contents of line loss statistics?

(1) Line loss rate and power factor of 35kV and above transmission lines and substation interconnection lines.

(2) Line loss rate and power factor of 10kV distribution lines.

(3) Lossy line loss rate, comprehensive line loss rate and power factor of each substation.

(4) Substation busbar power imbalance rate.

(5) Substation main transformer power loss.

(6) Metering meter line loss rate and power factor of dedicated lines that are not at the property boundary.

(7) Line loss rate of urban and rural low-voltage substations.

(8) Network loss rate and power factor of each voltage level (such as 500, 330, 220, 110, 35kV, etc.).

(9) Comprehensive line loss rate and power factor of the whole company.

(10) Completion of line loss indicators.

Introduction to line fittings What are the basic requirements for line loss statistics?

(1) Use modern means to realize the automatic generation of line loss rate and reduce human intervention.

(2) Enterprises with conditions should realize online calculation of line loss rate.

(3) Calculate line loss by voltage, line and substation.

(4) Basic data (such as power supply and power sales) must be accurate and true.

(5) The calculated line loss rate and power factor data are accurate.

(6) For changes in meters or transformers, meter abnormalities, etc., the power should be replenished and refunded in time.
