Roles and Responsibilities of SLDC- State Load Dispatch Center in India

As per section 33 of Electricity Act – 2003 (Central Act 36 of 2003), SLDC-State Load Dispatch centers performs:-

SLDC- State Load Dispatch Center suppose to carry out following functions or Roles and Responsibilities of State Load Dispatch Center.
Scheduling:

All Open Access users (excluding wind and mini hydel and generating stations having total capacity not less than 5 MW and up to 15 MW opting for injection under UI) that are connected to the Grid shall schedule and dispatch according to instructions given by SLDC. The methodology of scheduling shall be according to provisions of Gujarat State Grid Code and Clauses 26 and 44 of GERC Tariff Regulations.
Gaming:

SLDC should see that no gaming is done while declaring capacity by generators.
Energy Accounting:
A State Energy Account, for the billing and settlement of ‘Capacity Charge’, ‘Energy Charge’, ‘UI Charge’ and ‘Reactive Charge’ shall be prepared by the SLDC.
The SLDC shall be responsible for computation of actual net MWh injection of each generating station and actual net drawl of each beneficiary (Distribution Licensee / Open Access Consumer), 15 minute – wise, based on the above mentioned meter readings and for preparation of the State Energy Accounts.
SLDC shall periodically review the actual deviation from the dispatch and net drawl schedules being issued, to check whether any of the constituents are indulging in unfair gaming or collusion. In case any such practice is detected, the matter shall be reported to the Member Secretary, SPC for further investigation / action.
Commercial Settlement of Energy:
State pool accounts for (i) payments regarding unscheduled – interchanges (UI Account) and (ii) reactive energy exchanges (Reactive Energy Account), shall be prepared by the SLDC on a weekly basis and these shall be issued to all constituents by Wednesday of the Week following the next week for the seven-day period ending on the previous Sunday mid-night. Payment of UI charges and reactive energy charges shall have a high priority and the concerned constituents shall pay the indicated amounts within 7 (seven) days of the statement issued into a State UI pool account or a State Reactive Energy Account operated by the SLDC. The agencies who have to receive the money on account of UI charges or reactive energy charges would then be paid out from these pool accounts, within three (3) working days.
The SLDC shall table the complete statement of the State UI account and the State Reactive Energy account in the SPC’s Commercial Committee meeting, on a quarterly basis, for audit by the latter.

Right Of Way / Way Leave Clearance for various Electrical Power Transmission Line

Width of maximum right of way permitted as per forest conservation act ‘1980 and its subsequent amendment dated 25 th October, 1992, are as per Table 1.  Researches are being carried out for further optimizing the Right of Way. Guidelines of forest environmental rules shall be followed to avoid excessive tree cutting i.e. all the trees should be cut from root level in the 3 m corridor below each line conductor / earth wires.  In the balance corridor, trees branches are only to be lopped to attain the specified clearance as per Table 1. Table 1  – Guidelines for Right of Way as per forest conservations act 1980 and subsequent amendment dated 25 th October, 1992 Line voltage (kV) 66 110 132 220 400 500 HVDC 765 Row width (Meter) 18 22 27 35 52 52 85 Electrical clearance:   Electrical clearance while power lines crossing each other. In case of power line crossings, minimum clearance between lowest conductor of line and ground wire / top conductor of ...

What is CSD (Controlled Switching Device) in Electrical System

Definitions CSD (Controlled Switching Device): A device that is installed at the relay and control panel to overcome the transient behaviour of voltage and current during switching. This device synchronizes the switching of each pole of the circuit breaker according to the zero crossing of the corresponding phase. This device is also known as a phase synchronizing device, or PSD for short. Requirement When we switch off an online circuit breaker to disconnect an inductive load, we ideally want to interrupt the current of the system at the zero crossing of the current waveform. However, this is practically impossible to achieve. In a normal circuit breaker, the current interruption may occur near the zero crossing point, but not exactly at it. Since the load is inductive, this sudden interruption of current causes a high rate of change of current (di/dt), which results in a high transient voltage in the system. In low or medium voltage power systems, this transient voltage during circui...
