1. Instruct the management and power management department to calculate the line loss theory and compare it with the actual situation to obtain a more reasonable line loss indicator. The indicator will be released to the grassroots departments in the annual, quarterly and monthly months and included in the economic responsibility system. . In addition, the user's meter reading rate, voltage pass rate, permittivity availability rate, capacitor input rate and energy-saving activities should be assessed for small line loss indicators, and rewards and penalties should be clearly defined to mobilize employee management enthusiasm.
2. Reactive power management In addition to normal power factor assessment, for some users only care about whether the power factor is greater than 0.9, and do not pay attention to reactive power reversal, selectively use large power, power factor close to 1. The user installs a two-way reactive energy meter; according to the characteristics of the load power, select the appropriate capacitor switching basis.
3. Harmonic management With the increase of nonlinear power load in the power grid, such as rectifier equipment, electric melting equipment, electric locomotives, energy-saving appliances, fluorescent lamps, televisions, computers, etc., harmonic pollution in power distribution systems is becoming increasingly serious. Harmonics not only reduce the power factor of the system, but also generate thermal effects in equipment and lines, resulting in power loss. Therefore, the electricity management department should detect the presence of harmonics and the degree of pollution of the system, so that there are counts and harmonic suppression measures should be taken when necessary.
4. Measurement and management of correct energy measurement is not only the basis for reducing line loss, but also the basis for assessing technical and economic indicators. The meter should be regularly checked and verified, and the magnification should be adjusted in time to reduce the comprehensive error of the energy metering device. For the energy meter of the key parts, the advanced all-electricity meter should be used as much as possible, and the collection system should be promoted as much as possible.
5. Statistical analysis of the division, fragmentation, and voltage level for line loss statistics, regular analysis of line loss status, analysis of problems in voltage and reactive work, and improvement measures to ensure the completion of line loss indicators. Do a good job of monthly and annual line loss rate curves, master the system active, reactive power flow, power factor, voltage and line loss, etc., to provide basis for meeting next year's load growth, improving power quality, system economic operation and developing damage reduction measures.
