power systems loss

How billing timing difference affects systems loss data? Billing timing differences can have an impact on power system loss data, especially if the data is being used for analysis or performance monitoring purposes. This is because billing data is typically collected at different times than system loss data, and these differences can affect the accuracy and reliability of the data. One potential issue is that billing data is often collected on a monthly or quarterly basis, whereas system loss data may be recorded at a higher frequency, such as every 15 minutes or hourly. This means that the billing data may not accurately reflect changes in power consumption or losses that occur on a more granular time scale. Another potential issue is that billing data is usually based on customer meter readings, which are affected by a range of factors, such as meter accuracy, measurement errors, and tampering. This can result in inaccuracies in the billing data, which can in turn affect the accuracy...

PRESENTATION ON POWER DISTRIBUTION SYSTEM LOSSES BY TAO HONG Presented by Tao Hong, Ph.D., lecture at ABB, FL, April, 2011 This is a very good presentation prepared by Tao Hong.

Authored by: MARINA YUSOFF*, ASNAWI BUSRAH*, MALIK MOHAMAD*, MAU TENG AU** Abstract: - This paper presents an approach to estimate technical losses in utility’s distribution network based on feeder’s load profile and characteristics, such as such as length, peak demand to installed capacity ratio, and load distribution profile. The developed methodology is implemented in spread sheets format, which is simple and user friendly. It requires minimum set of input data, while giving reasonably accurate results. The approach is tested on a real TNB distribution network and the results are reasonably accurate. Additionally, the spread sheet developed based on the methodology could also be used to perform various energy auditing exercises.

BREAKING DOWN SYSTEM’S LOSS COMPONENTS TUTORIALS How Electric Utilities Compute for the overall system’s loss value? We have discussed in our previous topics the main components in computing for the system’s loss of a typical electric utility namely the Purchased, Sold and Company use kilowatt-hours. The main principle behind the determination of system’s loss revolves mainly in the amount of unaccounted kilowatt-hour loss in comparison to the total kilowatt-hour purchased. Electric Utilities system’s loss differs from one another due to the reason that each utility possesses a unique network of electrical system. Some may have a dense loading profile while others may have relatively scattered loads. The usual reason why some utilities have higher line loss can be explained by the presence of over-extended lines just in order to serve customers in the remote area. Most electric utilities/cooperatives are supplied with electricity from more than one source to ensure rel...

ADMINISTRATIVE LOSS What is an administrative loss? Widely accepted fact is that losses is just those technical and non-technical ones. However, some electric utilities shall we say electric cooperatives that includes Administrative loss. The Administrative Loss is the component of Distribution System Losses that accounts for the electric Energy used by the Distribution Utility in the proper operation of the Distribution System. This shall include the electric Energy consumption of connected essential electrical loads in the following facilities, subject to the approval by the country's regulatory commission. Distribution Substations; Offices of the Distribution Utility; Warehouses and Workshops of the Distribution Utility; Other essential electrical loads of the Distribution Utility. Administrative losses is simply the energy consumption of any infrastructure, substations, or anything that is deemed necessary for the operation of the utility. Administrative Loss Adm...

How to determine the electric utility's overall power system's loss? Solving for an Electric Utility's Overall system's loss can be easier than you can think of. Distribution Utilities computes their over all Percent System's loss  in a very simple manner. The result of this computation serves as a signal on how the company is doing with respect to minimizing their energy losses and how are they performing.
