1.1 Electricity System
The electricity system refers to the energy balance system, such as the internal use of the self-designed Xili process equipment 1.2 The boundary of the electricity system
The boundary of the electricity system is the boundary of the electricity system. When the electricity source is suitable, it is the boundary of the electricity system. The user's payment letter should be based on the object of the electricity prohibition and the same standard to be achieved. Research and determine. The part outside the boundary is outside the boundary.
1.3 Electric energy balance
Electric energy balance is the whole process of supplying electric energy [disk], establishing the effective energy [and the balance relationship between the head-turning electric energy [A]] within the boundary of the power consumption system determined by the vehicle!
According to the law of energy calculation, the balance relationship of the power consumption system is: its supply electric energy [(W: = effective electric energy E) + loss related energy ((F) electric energy impact model (as shown in Figure 1)

3 Principles of electric energy balance
In order to ensure the efficiency and reliability of the power system, when conducting power consultation, the following classic rules a are followed, and the law of constant energy is followed;
, there are major standards and current classifications of experts:
. For the construction of the power system of this type, the boundary of the potential system must be inspected and the object must be properly considered to achieve the expected balance. 4 Methods of energy balance 4.1 Direct measure method Through the positive supply unit [to allow the effective energy utilization rate, 4.3 Inter-exploration method Through the actual loss of the network energy products according to the table 1. Calculate the remaining energy utilization. 5 Determination of electric energy) .1 Determination of electric energy +: The ratio of the share to the meter method is required, and the simple power method is also called the periodic power method for measurement. 5.2 Test conditions 5.2.1 The system composition is positive, 5.2, 2 The use of Sichuan belt-shaped company does not allow the expected specifications. 5.2. [The system of this type can be measured in detail, with the expected retention or this beautiful power system. .2. Still changing! Niu system, on the child, the test week made a number of periods. .2. Test piece, test stock get the number of periods, according to the implementation conditions to reduce CB8222-7

Each service center component shall supply the final power in the form of a share of the total power supply to each branch of the power system: the power supply of the power system (power research). Through
Figure 4 and Figure 5, the content and steps of the power balance of the enterprise equipment are summarized. a.
